The photo at left shows small particles of metallic gold in quartz taken from the mountains of Canada. Sections of gray colored quartz in the specimen have this appearance because of the finely ...
However, arsenic is generally not recovered from these sources, which are instead disposed of in an environmentally safe manner. Arsenic has been commercially recovered from realgar and orpiment (arsenic sulfide minerals) in China, Peru, and the Philippines, from cobalt-arsenide ores in Morocco, and from copper-gold ores in Chile2.
Artisanal and small-scale gold mining (ASGM) is present in over 80 countries, employing about 15 million miners and serving as source of livelihood for millions more. The sector is estimated to be the largest emitter of mercury globally. The Minamata Convention on Mercury seeks to reduce and, where feasible, eliminate mercury use in …

Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold. During its life, a number of factors – such as the price of gold or input costs – will affect which areas of an ore body are deemed profitable (economic) to mine.
