Jan 09, 2018· Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold .
Gold is an almost nonreactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.
Aug 13, 2018· Raw materials such as iron, gold, copper, nickel, and tantalum that are mostly mined from open pits from solid rock were classified to have a medium EHP, and raw materials mostly extracted from underground mining were assigned a low EHP. The latter applies to graphite and tungsten in Table 2. Use of auxiliary substances
