Ores containing silver in Arsenic and Antimony combinations offer considerable difficulties in cyanidation and it has usually been considered that the removal of these compounds by concentration was the only way to deal with them. G. H. Clevenger, however, when working on the ores of the Nipissing Mining Company of Ontario, Canada, found that by grinding exceedingly fine and treating with

Humans are also affected by mining. There are many diseases that can come from the pollutants that are released into the air and water during the mining process. For example, during smelting operations enormous quantities of air pollutants, such as the suspended particulate matter, SOx, arsenic particles and cadmium are emitted.

High-arsenic copper concentrates. The fluid bed partial roaster processes high-As copper concentrate to produce a calcine with a low As content and high-copper concentrate. The roaster complex has an integrated effluent plant which removes the As content from the process water. Effluent is treated using calcium arsenite precipitation.
