Gold Refining Process by Aqua Regia Mineral Processing
· The Gold Refining Process by Aqua Regia was introduced at the Pretoria Mint after the Miller process had been tried and abandoned owing to the alleged difficulty of treating the gold bullion extracted by the cyanide process In the aqua regia process the gold is dissolved and precipitated It is made very difficult if the silver exceeds 100Aqua Regia is obtained by mixing hydrochloric acid and nitric acid at 3/1 ratios by volume Gold alloys, jewelry scrap and even gold ore are processed in the gold refining plant In the Gold Refining Plant by Aqua Regia, the chemicals to be used are designed with the appropriate equipment until the process is completed and the final product isGold Refining Plant By Aqua Regia
