Abstract
Process for the flotation of anode slime from copper electrolysis comprising subjecting the anode slime, as a preliminary treatment, to attrition treatment in combination with a copper leaching treatment in a medium of an acid solution. The floated material obtained from the flotation is continuously subjected to three processes of roasting, melting and cupellation in a rotary furnace lined with refractory bricks for recovery of good quality silver anode.
