A platinum refinery takes raw ore concentrate or recycled scrap — mostly spent catalytic converters — and turns it into metal that is at least 99.95% pure, the current industry purity standard for platinum group metals (PGMs) used in catalysts, electronics, and jewelry, per Specialty Metals. Platinum traded at $1,735.10/oz on August 18, 2026, per KITCO and JM Bullion (live chart here), and that price is exactly why refining economics matter: at over $1,700/oz, even a few percentage points of recovery efficiency determine whether a refining operation is profitable. This article walks through how to refine platinum from ore versus scrap, what recovery rates you can actually expect, what it costs, and how to find a refinery if you’re holding material that needs processing.

What a Platinum Refinery Actually Does

Refining is the last, and hardest, step in getting usable platinum: separating it from everything it’s mixed with — rock, iron, other platinum group metals, or the ceramic substrate of a catalytic converter — down to a purity level that industrial buyers will accept. A refinery is not a smelter and it’s not a mine; it’s the chemical-separation facility that sits between raw feedstock (ore concentrate or scrap) and a finished bar, sponge, or salt of platinum metal.

Two very different supply streams feed a platinum refinery, and which one you’re dealing with changes the whole process:

• Primary ore refining: Concentrate from platinum group metal (PGM) sulfide ore, mined from layered igneous intrusions. In the US, the only primary PGM byproduct source is the copper-nickel sulfide ore mined in Michigan’s Upper Peninsula — the USGS does not publish a separate recovery-yield figure for platinum from these operations, so if you need that number for a specific project, request it directly from the mine operator or from USGS’s Michigan district office.
• Secondary (recycled) refining: Spent catalytic converters, electronic scrap, and jewelry scrap. This is the faster-growing stream and the one most readers searching for a “platinum refinery” actually mean.

Refining Platinum From Ore

Ore-based refining starts long before any chemistry happens — it starts with concentrating low-grade rock into something worth smelting. Platinum group metal ores typically run at grades measured in single-digit grams per tonne, so the ore has to be crushed, milled, and floated to raise PGM content before smelting is even economical. From there:

1. Flotation concentration — sulfide ore is ground and floated to separate PGM-bearing sulfides from waste rock.
2. Pyrometallurgical smelting — the concentrate is smelted at high temperature to produce a PGM-rich matte, driving off iron and silicate rock as slag.
3. Converting — the matte is further processed to concentrate PGMs and remove base metals like nickel and copper, which are typically recovered separately as valuable byproducts.
4. Hydrometallurgical separation — the converter matte is dissolved (commonly in aqua regia or similar chloride-based leach systems), and individual PGMs — platinum, palladium, rhodium, iridium, ruthenium — are separated by selective precipitation, solvent extraction, and ion exchange.
5. Final refining and finishing — repeated purification cycles bring platinum to the 99.95%+ purity standard used across catalyst, electronics, and jewelry markets.

This is capital-intensive, slow, and geographically concentrated. The world’s primary PGM ore supply comes overwhelmingly from South Africa and Russia, not the US — the USGS 2026 Mineral Commodity Summary tracks US net import reliance and end-use purity standards for PGMs, but it does not publish a consolidated, facility-by-facility list of US refining capacity in tonnes per year. If you need current US throughput figures for a specific business case, USGS’s annual Platinum-Group Metals chapter is the place to start, and it’s worth checking each new edition since the data is compiled yearly, not continuously.

Refining Platinum From Catalytic Converters and Scrap

Most people who search “refine platinum” outside a mining or investment context are asking about recycling — specifically, catalytic converters. This is where the process is faster, cheaper per unit of output, and where most of the growth in the industry is happening.

The automotive catalytic converter recycling market is projected to grow at a 3.1% compound annual growth rate between 2025 and 2033, according to DataInsights Market’s automotive catalytic converter recycling report. Platinum and palladium recovery together account for more than 60% of the value generated by that market as of 2025, per the same source — the metal recovered from the honeycomb substrate inside a converter is worth far more than the steel canister around it.

Recovery rates from catalytic converter catalysts run 80–94% of contained platinum, depending on the process and feedstock condition, according to US Patent Database records on catalyst recovery methods (US Patent 5,160,711). That range matters if you’re evaluating a recycler’s quoted payout: a facility recovering near the top of that band is extracting meaningfully more value from the same converter than one at the bottom.

Automation is now standard practice in this segment. As of 2025, 68% of US recyclers used automated metal recovery systems rather than manual sorting and hand-processing, per DataInsights Market. Automated X-ray fluorescence (XRF) sorting and automated leach-and-precipitate lines are the two most common upgrades driving that number, since they cut both labor cost and the sampling error that comes with manually grading converters by eye.

Why Recovery Rate Varies by 14 Points

• Substrate condition: A converter that’s been through a fire or heavy road salt exposure loses recoverable metal to degradation.
• Process choice: Wet chemical leaching typically clears the higher end of the 80–94% band; older thermal-only processes cluster lower.
• Batch size and consistency: Automated XRF sorting (part of that 68% adoption figure) lets a facility blend batches for more predictable, higher-average recovery than hand-sorted lots.

Use the figures above to estimate what a batch of catalytic converters could be worth before you take it to a refiner — enter your own converter count, estimated platinum content, and the recovery rate your refiner quotes.

Assumptions: uses the 80–94% recovery band reported for catalytic converter catalysts (US Patent Database) and the platinum spot price you enter — refiners typically pay a percentage below spot to cover their own processing margin, palladium and rhodium content are not included, and this does not account for converter-grading fees or minimum-lot charges some refiners apply.

Step-by-Step: The Refining Process

Whether the feedstock is ore concentrate or catalytic converter scrap, the finishing chemistry converges on the same core sequence once you're past the initial concentration step:

Visual List: Key Stages of Platinum Refining

• 🔬 Concentration: Ore is floated to raise PGM content; scrap converters are crushed and the ceramic substrate is milled to expose the washcoat containing the metal.
• 🔥 Pyrometallurgical Smelting (ore route): Concentrate is smelted at high temperature, producing a PGM-rich matte and separating unwanted rock and iron.
• 💧 Hydrometallurgical Refining: The matte, or the milled catalyst powder, is dissolved — commonly via aqua regia or a chloride-based leach — and PGMs are selectively separated via precipitation, solvent extraction, and ion exchange.
• 🔄 Recovery From Spent Catalysts & Scrap: This route recovers 80–94% of contained platinum, per US Patent Database process data, generally using less energy and fewer reagents per unit of output than processing virgin ore from scratch.
• 📏 Finishing & Quality Control: Final steps bring the metal to the >99.95% purity standard, per Specialty Metals, and format it as sponge, ingot, or salt depending on the buyer's specification.

What Feeds a Platinum Refinery

• 🌋 Primary feedstock: Ore concentrates, sourced overwhelmingly from South Africa and Russia; the sole US byproduct source is Michigan's copper-nickel sulfide operations, with recovery yields not disclosed in USGS summaries.
• 🔁 Secondary feedstock: Spent catalytic converters (automotive and industrial), electronic scrap, and jewelry scrap.

Diversified feedstock is the operating strategy of choice for refiners heading into any given year: blending recycled material with ore concentrate reduces exposure to ore-grade volatility and to the geopolitical concentration of primary supply in two countries.

Purity Standards and Quality Control

The refining industry's current benchmark is >99.95% purity for finished platinum, per Specialty Metals — this is the threshold that qualifies metal for catalyst manufacture, electronics-grade components, and investment-grade bars. Getting there requires multiple purification cycles because PGMs are chemically similar to each other and hard to separate cleanly in a single pass.

• Surface area engineering: For catalyst applications, platinum must be formulated to maximize surface area, which is a separate specification from bulk purity and depends on the intended reaction (automotive exhaust vs. ammonia synthesis vs. petroleum reforming).
• Co-produced PGMs: Palladium, rhodium, iridium, and ruthenium come out of the same feedstock stream and are typically separated and sold individually rather than left blended with the platinum.

What's not publicly published: a per-kilogram environmental remediation cost for refining, or a state-by-state registry of US refining facilities and their permitted capacity. Neither USGS nor EPA maintains a consolidated public dataset on either point. If a specific number matters for your project — say, evaluating a refiner's environmental compliance cost structure — the direct path is to request it from the facility's environmental permit filings at the relevant state environmental agency, since permits (not the refiner's marketing material) carry the enforceable capacity and discharge figures.

Finding a Refinery Near You

If you're searching for a "refinery near me," the practical answer depends on what you're bringing in. Large-scale primary PGM refining in the US is concentrated among a small number of specialist precious-metals refiners — Elemetal is one of the largest, and its own site documents its recovery methods and domestic refining role (Elemetal's platinum refining page). Specialty Metals is another established US refiner publishing its environmental practices publicly (Specialty Metals' platinum refining standards).

For smaller quantities — a handful of catalytic converters, jewelry scrap, or lab residues — most transactions actually go through regional recyclers and brokers rather than directly to a primary refiner; those brokers then aggregate material and sell it upstream. Because there's no single public directory of every licensed platinum refining facility and its capacity, the reliable way to find and vet one is:

1. Ask directly for their quoted recovery rate and check it against the 80–94% published range.
2. Ask whether they use automated recovery/sorting systems — 68% of US recyclers now do, per DataInsights Market, and it correlates with more consistent payouts.
3. Check their state environmental permit status directly with the state agency, since neither USGS nor EPA consolidates this nationally.
4. Get a settlement sheet that itemizes platinum, palladium, and rhodium separately, priced against a stated spot reference date — not a single lump-sum "scrap value."

Refining Petroleum and Other Refinery Terms People Search

A few related searches are worth a direct answer even though they sit outside platinum refining proper. Refining petroleum is a fundamentally different industrial process — crude oil is separated by distillation and catalytic cracking into fuels and petrochemical feedstocks, and it happens at oil refineries, not metals refineries. The one genuine overlap between the two industries: platinum-based catalysts are used inside petroleum refining itself, in catalytic reforming units that boost octane in gasoline production, which is a separate application from the automotive catalytic converters discussed above. If you landed here looking for petroleum refinery capacity, throughput, or regulation, that's a distinct industry and a distinct set of data sources (EIA, not USGS).

Refining platinum and platinum refining as phrases both describe the same process detailed above — ore or scrap in, >99.95% pure metal out — and everything in this article's process-steps and recovery-rate sections applies directly to both.

Where Refined Platinum Ends Up in Agriculture and Industry

Refined platinum's largest single demand driver is emissions catalysis, and that reaches agriculture directly through diesel engines. Modern tractors, combines, and forestry equipment sold in the US carry platinum-group-metal catalytic converters to meet EPA nonroad diesel emissions standards, which is why the catalytic converter recycling stream discussed above is directly tied to the agricultural and construction equipment fleet, not just passenger cars.

Refined Platinum's Working Roles

• Emissions control: Diesel tractors, harvesters, and forestry vehicles use platinum-group-metal catalytic converters to filter NOx and particulates.
• Fertilizer and ammonia production: Platinum-based catalysts are used in ammonia synthesis (Haber-Bosch process) and downstream nitric acid production for fertilizer manufacture.
• Process sensors: Platinum resistance temperature sensors provide monitoring in fertilizer and chemical processing lines.
• Corrosion-resistant alloys: Platinum alloys extend equipment life in irrigation and chemical-handling components exposed to corrosive fertilizer solutions.

FAQs on Platinum Refineries and Refining

• Q: What purity does refined platinum need to reach?
  A: The current industry standard is above 99.95% purity, per Specialty Metals — this applies to platinum from both ore and recycled scrap routes.
• Q: How much platinum can actually be recovered from a catalytic converter?
  A: Recovery rates run 80–94% of contained platinum, according to US Patent Database records on catalyst recovery processes. Where a specific refiner falls in that range depends on their process technology and the converter's condition.
• Q: Is there a refinery near me that handles small quantities?
  A: There's no single public directory of licensed platinum refiners and their capacity, since USGS and EPA don't publish a consolidated registry. For small lots, most material moves through regional recyclers who aggregate and sell upstream to primary refiners like Elemetal or Specialty Metals; verify any local recycler's recovery rate and state environmental permit before transacting.
• Q: What's the difference between refining platinum and refining petroleum?
  A: They're unrelated industries. Petroleum refining separates crude oil into fuels via distillation and cracking; platinum refining separates PGM metal from ore or scrap via smelting and hydrometallurgy. The one link is that petroleum refineries use platinum-based catalysts in their own reforming units.
• Q: Where does the platinum price come from and how often does it change?
  A: Platinum trades continuously on global metals markets; KITCO and JM Bullion publish live spot pricing (KITCO's chart), which was $1,735.10/oz on August 18, 2026. Check that link directly rather than relying on any fixed number, since it moves daily.
• Q: Can satellite-based mineral detection reduce mining's environmental footprint upstream of refining?
  A: Yes — Farmonaut's methods enable target validation without disruptive ground surveys, trenches, or drill campaigns, eliminating exploration-phase emissions and habitat loss before any ore ever reaches a refinery.
• Q: How do I get a quote for satellite-driven mineral prospectivity or mapping?
  A: Visit our Get Quote page or Contact Us to discuss your project needs.

The Bottom Line on Platinum Refining

Platinum refining converts two very different feedstocks — mined PGM ore and recycled catalytic converter scrap — into the same >99.95%-pure end product, and the economics of either route track two numbers you can check yourself at any time: the spot price (currently $1,735.10/oz per KITCO, moving daily) and the recovery rate a given process actually clears (80–94% for scrap, undocumented for the US's sole ore-byproduct source in Michigan). The recycling side of the industry is growing at a projected 3.1% CAGR through 2033, and automation — now used by 68% of US recyclers — is the main lever pushing recovery rates toward the top of that band rather than the bottom.

None of that requires taking any single source's word for it. Check KITCO for the current spot price before any transaction, ask any refiner or recycler to quote their specific recovery rate against the published 80–94% range, and verify a facility's environmental compliance status directly with the state agency that issued its permit, since no federal registry consolidates that data. That's the durable checklist — it holds regardless of where the spot price or the CAGR forecast sit next time you read this.
