Autoclave Leaching of Arsenic from Copper Concentrate and Distribution of Arsenic in the Environment Arsenic

The best indices for autoclave leaching of copper concentrate containing enargite and arsenopyrite were obtained with alkaline breakdown which made it possible to extract into solution up to 99 arsenic and concentrate copper within cakeThe arsenic rich flue dust and other arsenic containing residues from domestic smelters are shipped to a single copper smelter where the arsenic is separated by controlled roasting and processed to a commercial form The arsenic free calcine is smelted to recover other metals
