Copper anodic slime which is an insoluble residue of copper electro-refining process contains valuable elements such as gold, silver, selenium and tellurium and is a byproduct of copper ingot production. Copper anodic slime contains 0.12% gold approximately. The common methods to extract gold from copper anodic slime are hydrometallurgical processes. The aim of this research is extraction and recovery of gold from copper anodic slimes by means of magnetite nanoparticles. For this, copper anodic slime was leached with nitric acid by which elements like silver, copper and iron dissolved while gold remained in the solid phase. The remained solid phase...
