Read MoreExtraction 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.
Read MoreGold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value.

Read Morebecause they are mined. I suggest that a complete listing of mineral ores and concentrates would be SITC 27 + 28 + 32 + 66 + 97. I include gold metal here because most gold mines concentrate the gold to refined bars on site, a fairly simple process requiring only small furnaces and one laborer. To exclude section 97 would be to exclude gold mineral
