Midwest Refineries – Precious Metal Refiners & Gold Buyers
Platinum Buyers, Smelters, Refiners, Assayers and Brokers of all Platinum Metal
Platinum is among the rarest and most valuable metals on earth. That makes choosing the right refinery one of the most important decisions you can make when it’s time to sell. The wrong buyer — one who hides fees, lowballs assay results, or gives you a fraction of spot price — can cost you thousands.
Midwest Refineries has been buying, smelting, and refining platinum group metals since 1939. We’re a family-owned operation now based in Lakeland, Florida, serving customers in all 50 states: laboratories, hospitals, manufacturers, jewelers, estate liquidators, and individuals. We charge zero fees, pay competitive percentages, and give you a straight answer every time you call.
Get Maximum Value for Your Platinum — From America’s Most Trusted Refinery
Platinum shows up in more places than most people realize — laboratories, operating rooms, industrial facilities, jewelry benches, and estate collections. Wherever your platinum came from, we have the expertise and equipment to process it accurately and pay you fairly.
We Buy Platinum from Every Industry and Source
Our customers include university and private research labs liquidating crucibles and labware, hospitals and medical device companies with platinum catheter tips and implant scrap, industrial facilities with thermocouple wire from furnaces and sensors, jewelers and estate liquidators with platinum jewelry and bench scrap, and private individuals with inherited platinum coins, bars, or jewelry.
If you’re not sure whether what you have qualifies, just call. We’re happy to help you identify your materials before you commit to shipping anything.

Why Platinum Sellers Choose Midwest Refineries
85+ Years of Trust
Midwest Refineries was founded in 1939 and is now led by Joanna and Raul Acosta, who together have more than 40 years of daily operational experience. Our repeat customer base — from individual hobbyists to university physics departments — reflects a reputation built one honest transaction at a time.
Platinum is too valuable to trust to imprecise methods. Our laboratory processes every order with modern equipment to determine exact metal content. You receive payment based on actual platinum — not estimates, not arbitrary deductions.
No refining fees, no assay fees, no treatment charges, no handling fees. What we quote is what you receive.
Many platinum materials — thermocouple wire, laboratory alloys, industrial scrap — contain recoverable palladium and rhodium alongside platinum. On orders of 4 troy ounces or more, we assay for all three metals and pay you on every one of them. Several of our customers have been pleasantly surprised to receive settlement on palladium and rhodium they didn’t even know was present in their scrap.
A single piece of platinum jewelry and a shipment of 40+ ounces of thermocouple wire are both welcome. We serve every customer at every scale with the same care.
Exactly What You'll Receive No Hidden Fees, No Surprises.
We’re straightforward about our pricing. Here’s the complete payout structure:
Platinum (pure content)
90% of pure platinum content
Palladium (pure content)
80% of pure palladium content
Rhodium (pure content)
80% of pure rhodium content
Spot price applied
Market price on settlement day, less $25 back of bid on platinum shipments
Minimum order required
None — all amounts welcome
Multi-metal assay threshold
Orders of 4+ troy oz. receive full platinum, palladium & rhodium assay
Orders under 3 troy ounces are purchased outright based on average melt weight loss and purity. Orders of 3 troy ounces or more are melted and assayed for exact platinum content. Orders under 4 troy ounces are settled on platinum content only — multi-metal assays (palladium and rhodium recovery) require a minimum of 4 troy ounces.
A Word on the “98–99%” Claims You’ll See Elsewhere
Refiners who advertise payouts of 98–99% recover their costs through refining fees, assay fees, treatment charges, handling fees, and inbound weight fees. No refinery operates on 1–2% margins. At Midwest Refineries, we charge no fees at all. Our payout percentages are your complete, actual return.
Settlement options: Check | Bank Wire ($35 domestic / $60 international) | Exchange for precious metal coins, bars, or rounds (call for availability).

What Our Platinum Customers Say
Our platinum customers range from estate liquidators and individual sellers to university research departments and international industrial companies. Here’s what they’ve told us:
“This is my third time doing business with you selling platinum scrap wire. We have been very satisfied with how Midwest has purchased our scrap platinum in the past and will highly recommend your services to our associates.”
“I couldn’t believe the check I received for the 138 grams of platinum wire I sent to your firm. I am an estate liquidator and truly didn’t know at the time whether it was platinum or silver or junk. I really want to thank you for being so honest. I have told friends about you and will definitely use Midwest Refineries again.”
“I was surprised to receive my check for the scrap collected from rebuilding two heat exchangers. I thought the material contained only gold but was delighted to receive settlement on platinum and palladium also. The additional funds will come in handy. Thanks for your honest evaluation of my scrap materials.”
