As one of the Northwest's premiere gold and silver refiners, we've utilized different disciplines of chemistry to maximize yields on many different materials. Liberty Refiners' precious metal refining process typically yields 99.99% pure gold and silver. The client then has the option to have us broker the metal, trade it for gold or silver rounds or bars, or have it back. For more information on the fascinating refining process, check out our Refining 101 page. There you will find a more detailed explanation of how gold and silver are refined.
