Arsenopyrite an overview ScienceDirect Topics,Arsenic can exist in sulfide minerals either as a dominant mineralforming element or as an impurity Arsenic release into nature is a slow process as a result of mineral weathering however physical forces such as grinding crushing and pulverization from mining activities greatly increase the release rate
2009-9-4Arsenic and Gold Mine Tailings FAQ What is arsenic Arsenic is a natural element that can be found distributed throughout the Earths crust. It is found in arsenopyrite, the same rock in which gold is often embedded. Many areas of Nova Scotia have elevated arsenic
Processing of the Giant Mine ore created arsenic trioxide dust as a by-product. Approximately 237,000 tonnes of the dust was produced and stored underground in 15 purpose-built chambers and mined-out stopes open holes in the mine resulting from the extraction of minerals. The dust is about 60 arsenic.
