What is Precious Metal Refining?
The precious metals refining process begins with the melting, sampling, and analysing the pure metal content of gold, silver, platinum, and palladium contained from unwanted jewelry, scrap materials, or other by-products from manufacturing.
Jewelers and pawnbrokers often accumulate significant amounts of scrap metal through repairs, resizing, liquidating outdated inventory, or purchasing unwanted jewelry from their customers. Refining this scrap is required for the recovery of valuable metals to be recycled and used in the manufacturing of new jewelry and even products used in the field of aerospace.
When it comes to processing precious metals, terms like “refinery” and “smelter” are often used interchangeably—but they’re not the same. Smelting is the process of melting down materials—often raw ores or mixed-metal scrap to form a homogenous metal alloy. The focus is a pyrometallurgical-based reduction and is strictly for the purpose of forming a metal alloy. Refining, however, goes beyond basic melting and alloying and implores the chemical dissolution and precipitation of select elements. Once segregated from its original base metal components, the gold, silver, platinum, and palladium are further upgraded, purified, and put into a metallic or fabricated chemical form to be used for future users.
Our Precious Metal Refining Process – Accuracy, Transparency & Speed
Mid-States operates a complete precious metal refining facility in Illinois, handling all stages of our precious metal refining services in-house from initial melt and sampling through to fire assay analysis and final settlement. Our process offers the highest levels of transparency and integrity, involving four key steps: weighing, melting, assaying, and final payment. Our customers’ precious metal material is weighed on receipt, documented, and photographed.
All weighing and documentation is verified by two persons. Our melting department professionals will once again confirm the weight received and then melt the material into a homogenous alloy and draw a molten metal pin sample before pouring it into an ingot. The pin sample is taken to the lab, where it will first be analyzed using XRF to provide our technicians the approximate metal content associated with that melt.
Note:(XRF (X-ray fluorescence) is the emission of characteristic "secondary" (or fluorescent) X-Rays from an individual element that has been excited by bombardment with high-energy X-Rays).
The preliminary X-Ray results also allow us to provide our customers with a meaningful preliminary value of their scrap materials, should they desire to take a partial “advance payment” against their final settlement. After completion of preliminary “instrumentation analysis”, the sample goes into the Laboratory for proper Corrected Fire Assay analysis
Fire assay is a precise, lab-based method for measuring the content of precious metals such as gold, silver, and platinum in a sample. This technique determines the exact amount of gold, silver, or other precious metals present in the sample. It’s a method that dates back thousands of years, and is still considered the most accurate testing method in the refining industry.
Clients are welcome to observe each step, from receiving and weighing to melting and sampling. On completion of the Fire Assay, our in-house trading team helps you price your metal at the current market, or can apply any metal pricing that you’ve previously hedged/locked. Ultimately, clients will receive a detailed settlement report outlining all details related to that refining lot. Final payment is available by check, wire transfer, or ACH. We’re also able to return fine gold, silver, platinum, and palladium in the form of government, bank, or privately issued bullion investment products or grain.

Precious Metal Refining FAQs
We’ve compiled some of the most common questions we get when it comes to refining precious metals.
What is the most accurate method of precious metal analysis?
Fire assay is the most accurate method. In the fire assay process, completed within our Chicago-based facility, we melt and dissolve a sample and precipitate the fine metal contained.
How long does the gold refining process take?
Gold refining at Mid-States Recycling and Refining depends on the type of gold that’s being processed. Karat gold scrap can take as little as 1-5 business days, whereas gold from jeweler’s rugs or carpeting could take up to 10 weeks.
Can I send mixed metal scrap for refining?
You can send Mid-States Recycling mixed metal scrap. We will process multiple types of precious metal materials within a given scrap lot, as long as it results in a financial benefit for our customers.
Do you provide assay reports before payment?
We provide a detailed assay report prior to payment. Additionally, samples from your melt are always available to you for independent, third-party analysis.
Is precious metal refining tax-free?
When refined precious metals (gold, silver, platinum, etc.) are sold at a profit, the IRS classifies them as collectibles and they are generally subject to gains.
Who can sell precious metals for refining in the U.S.?
While our consumer base is from across the U.S., we only deal with precious metals at the wholesale and dealer level. Specifically, our customer base consists of jewelers and pawnbrokers. We do not deal directly with the public.
How do I ship precious metals securely for refining?
The most secure and economical way to ship your precious metals is through our Insured contracted Express Courier Services. We arrange for pick-up at your secure location, and your package is delivered to us the very next morning. Additionally, as a Mid-States customer, your shipping rate has a built-in 30% discount to normal Courier rates. Shipping charges are conveniently applied to your final settlement volume. You may also use Insured Registered Mail Service through the US Postal Service; however, you should expect transit times of 4 days or more for delivery.
What types of reports will I receive after refining?
Your completed Settlement Report will include everything including a description and the weight received, the after-processing weight, final assay, refining terms including the details for the payable percentages, processing and assay charges, and with the metal prices your payment was based on.
How do I find reliable precious metal refiners near me?
Location is no longer a preventative hurdle when it comes to refining your material. Mid-States provides secure, insured courier pickup directly from your location, with delivery to our Chicago-area facility the following morning. Clients across the country receive the same settlement terms and fire assay accuracy as our local customers.
What should I look for when comparing precious metal refining companies?
When evaluating precious metal refining companies, focus on four factors: whether assaying is done in-house or outsourced, whether fire assay or XRF-only analysis is used, settlement speed, and chain-of-custody documentation. A reputable precious metals refining company performs every assay on-site eliminating the third-party markups and delays that reduce your net payout at lesser operations.
How is refining precious metal different from smelting?
Smelting melts and alloys raw material. Refining precious metal goes further. It chemically separates and purifies each individual element (gold, silver, platinum, palladium) to a defined purity level. At Mid-States, the process of refining precious metal moves through four verified steps: weighing, melting, fire assay sampling, and final settlement, with full client visibility at each stage.
