Flotation of copper sulphide from copper smelter slag ...

2015-10-10 · Lowest copper recoveries were obtained with alkyl hydroxamate in single collector floation performance. It has been reported that the alkyl hydroxamate is not very selective for sulphide flotation. In case of copper slag most of the copper occur in the form of copper sulphide and shows very low response with alkyl hydroxamate.
