Massive, base metal arsenical gold ores are rare, and there are only a few deposits in the world. A typical arsenical gold ore contains arsenopyrite as the major arsenic mineral. However, some arsenical gold ores, such as those from Nevada in the USA (Getchel deposit), contain realgar and orpiment as the major arsenicbearing minerals. Pyrite, if present in an arsenical gold ore, may contain ...

Like many gold mines, the Yanacocha mine uses a cyanideheap process to extract tiny amounts of gold ore from rock. They start with an underground explosion creating a mix of gold, soil, and rock, sending Nitrates into the streams from the explosives, then use a wash of cyanide to dissolve the gold ore and make a liquid solution. Later in the process, an acid wash separates gold from the ...

This indicates that attempts to lessen the environmental impact of gold production should focus on these two stages. Mining and comminution are highly dependent on the grade of gold ore, as the lower the grade, the greater the amount that needs to be mined and the more crushing and grinding is required to extract the gold from the ore. As there is a general decline in gold ore grades it is ...
