2019-5-26The most effective hydrometallurgical processing of anode slime is based on a chlorination route. However, it requires special attention with respect to pollution problems and construction materials. To minimize the problems, a new hydrometallurgical approach was pursued for the recovery of valuable metals and metalloids from copper electrorefining anode slime. The process involved the ...

The purpose of a primary smelter and refinery is to produce copper, so the operation of any sub-system should not compromise this task. The main process stages for copper production include feed preparation, smelting, converting, fire-refining, anode casting, and electrorefining, also together six process stages or subsystems.

The present invention is concerned with a method for the substantially selective extraction of tellurium from copper electrorefining slimes. The method comprises maintaining a molar ratio AgSe, AgS or AgSeS at a value of about 2 or less in the slimes during leaching thereof in an autoclave. The excess of selenium andor sulphur allows the formation of Ag.sub.2 Se or Ag.sub.2 S, which ...
