THERMOMECHANICAL ASPECT OF SELECTIVE

2016-1-10  which mutilates flotation process. It is known that zinc cycle of copper–zinc ore flotation uses xanthate modifications that are not selective relative to pyrite. In view of the aforesaid, it is re-quired to design a process flow chart toward higher efficiency of separation of zinc minerals and pyrite in the zinc cycle of flo-tation.

Copper-Zinc ores - Danafloat

The flotation separation and recovery approach is quite similar to the Pb-Zn sulphide separation process. Sphalerite is depressed with zinc sulphate addition to the grind with sodium sulphide as an option for enhancing pyrite depression. Copper is floated in the first differential flotation stage at a

Gold-Pyrite ores - Danafloat

Natural pH is recommended for gold flotation. Alternatively using soda ash for pH adjustment can reduce gold depression. Where gold is associated with pyrite in base metal ores where iron sulphides are depressed and report to the tailings, a separate tailings pyrite flotation concentrate should be considered.

Sulfidation roasting of zinc leaching residue with pyrite for ...

2020-5-15  Zinc leaching residue (ZLR) contains high content of valuable metals such as zinc and iron. However, zinc and iron mainly exist in the form of zinc ferrite, which are difficult to separate and recover. This study proposed a new process involving sulfidation roasting, magnetic separation and flotation to recover zinc and iron in ZLR. Through sulfidation roasting of ZLR with pyrite, zinc and ...
