Offering full service precious metal reclaim solutions and precious metal management with short cycle times.
Receiving
When precious metal scrap is received at our refineries, it is carefully
weighed by two people using calibrated scales accurate to .001 oz. Material
items and weights are checked against customers' advised information.
Refining data is entered into our computer which generates customer receipt
and process control forms.
Preparing
for Sampling
A proper sample is representative of the total material, based on a scientific
sampling of homogenous materials. Customer material sent to the refineries
for reclaim is initially examined by experienced personnel, who choose
the best sampling preparation process dependent on the nature of the material
received. Processing may involve incineration, milling, screening, chemical
leaching or smelting.
Sampling
Precious metal scrap is melted in an electric induction furnace and sampled
in its molten state using vacuum sealed glass tubes. This method is preferred
rather than driling cast bars, which may be segregated. After the fine
screening process, dust is blended using scientifically proven "V"
type rotating blenders. Three samples are taken - one for our refinery
lab, one for the customer, and one sealed sample for possible umpire.
Assaying
Williams utilizes the classic fire assay process for Gold, which is the
globally accepted method of choice for maximum accuracy. Platinum, Palladium,
Rhodium and Silver are determined by either wet gravimetric or instrumental
procedures such as ICAP or Mass Spectroscopy. Assay data is entered into
our network computer, which calibrates the actual precious content used
for customer settlement.
Settlement
Settlement is calculated based on recovered net metal content and is valued
at set published metals markets less our charges. Williams offers many
settlement options dependent on our customer needs: check, wire transfers,
or credits of net dollar value to accounts.
Refining
Refining literally means to take some material, separate it into its constituents
and create a purified product. Unlike many so-called "middlemen refineries"
who only melt and assay scrap, Williams operates one of the largest, most
efficient chemical refineries in the country. Our 15,000 sq. ft. state-of-the-art
refining facility was specifically designed to refine precious metal scrap
materials received from our customers and our own manufacturing scrap
by-products. Gold, Palladium, Platinum, Silver, Rhodium, and Ruthenium
are refined to their purest forms and used on our production facility.
Environmental
Compliance
Williams' refining facility and operation meets or exceeds all governmental
regulations including OSHA, DEC and local Sewer Authority specifications.
We have experienced Safety and Compliance Engineers on staff, along with
highly capable associate technicians to monitor our processes, equipment
and effluent. All metals, precious and non precious, are recycled. No
