Gold processing, preparation of the ore for use in various products. Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earth’s crust. It occasionally is found as nuggets as large as 12 millimetres (0.5 inch) in diameter, and on rare occasionsGold: History of Use, Mining, Prospecting, Assay & Production,Extraction of gold and other precious metals from their ores by treatment with mercury is called amalgamation. Gold dissolves in aqua regia, a mixture of hydrochloric and nitric acids, and in sodium or potassium cyanide. The latter solvent is the basis for the cyanide process that is used to recover gold from low-grade ore.
Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study.
