Refining Gold Jewelry Scraps
When used for refining material that doesn''t contain PGMs, the inquartation and parting process is capable of producing gold of up to 99.99 percent purity. The process is particularly suited for treatment of low karat gold scrap, since large additions of copper or silver are unnecessary to achieve the desired 25 percent-or-less gold content.

Diamond / Stone Removal Process
· by Romantic » March 21st, 2014, 6:01 pm. I have decided to try an acid based stone removal process myself. This will be my first attempt at any sort of gold refining. What I have is about 13oz of mixed 10K & 14K Gold mountings with diamonds. All the items have been cut to where it is just the smallest bit of gold that is holding the stones.
Another process of pre-refining is the Alloy Correcti on, means adding gold during melti ng to reduce the Silver content less than 10% and so go to Aqua Regia or other Chloro- Hydric based processes like Wolwhill Electrolysis. You can understand that this process needs of a lot of gold and so has a very high stock metal cost.
How to Take the Impurities out of Gold | LEAFtv
Set the gold ore and a small quantity of lead in a cupel. Place the cupel in a blast furnace. Heat the mixture until the lead and gold ore liquefy. The blast furnace batters the cupel with hot air. The lead combines with other metals and forms oxide compounds that separate from the gold. This process works best with small quantities of gold ore.
Cupellation is a refining process in metallurgy where ores or alloyed metals are treated under very high temperatures and have controlled operations to separate noble metals, like gold and silver, from base metals, like lead, copper, zinc, arsenic, antimony, or bismuth, present in the ore. The process is based on the principle that precious metals do not oxidise or react chemically, unlike the ...
