Three environments/styles are most common: gold in greenstone belts, gold in porphyry deposits, and gold in epithermal deposits. Gold in Greenstone Belts Gold is found in Archean (rocks older …
Taking advantage of the natural tendency of charcoal to absorb gold dissolved in cyanide solution, the Chapman process (U. S. Patent 2,147,009) may have applications to unusual types of gold ores. It is not claimed that this method can compete with present cyanide methods when the ore to be treated is easily cyanided.
There is no method for separating gold from silver, or other precious metals, when smelting. The ore containing the metal when melted will form an amalgam – an alloy of gold and silver, or whatever precious metals are in your concentrates. Let the refinery separate precious metals – it9s really the easiest and cheapest in the long run.
What are the types of gold ore? Gold ore is categorized into two main types: lode deposits and placer deposits. Lode deposits are found in veins or rock formations, often deep underground. Placer deposits are formed by the erosion of gold from its original source and are found in riverbeds, beaches, or sedimentary environments, typically near ...
