Cobalt extraction

The calcine is subsequently leached with sulfuric acid from the spent copper recovery electrolyte Oxide concentrates are introduced at this leaching step to maintain the acid balance in the circuit Iron and aluminum are removed from the leach solution by the addition of lime, and copper is electrowon on copper cathod...

Leaching Studies of Spent Zinc

The hydrometallurgical processing of metal bearing residues is one of the established routes envisaging metals recovery In these processes, the leaching operation plays a central role as allows the solubilization of metals for further separation and recovery as pure products This route can be applied to spent domestic batteries recycling, which studies on sulphuric acid leaching of spent ....

Preparation of manganese sulfate from low

Abstract In this study, a method for preparing pure manganese sulfate from low-grade ores with a granule mean size of 047 mm by direct acid leaching was developed The effects of the types of leaching agents, sulfuric acid concentration, reaction temperature, and agitation rate on the leaching efficiency of manganese were investigated...
