Porphyry copper - gold ore is one of the important source of gold.Copper - gold ore processing characteristics due to the different ore types are closely related to the mineral composition of the ore.The gold ore will also appear in the native copper sulphide ore.The main reason for the low flotation recovery of copper and gold ore is the presence of a large number of clay.

Copper-gold sulfide ore processing flow
1,Recovery of gold - copper concentrate, suppression of pyrite.Due to the high gold grade of the tailings and often can not be abandoned.This process only applies to no particulate gold in the ore, or ore in gold is associated gold and low grade, most of the gold is present in the case of chalcopyrite.
2, the flotation process. Turn to gold - copper concentrate, iron sulfide concentrate, and finally was elected from ore tailings.
3, mixed flotation process, it is possible to obtain waste tailings.

Copper-gold sulfide ore flotation process
First, only adding a small amount of collector, easy flotation gold - copper minerals and pyrite particles elected into the mix concentrate, mixed concentrate flotation, must be added to the large number of inhibitors to suppress pyrite electiona high-grade gold - copper concentrate.Improve collector dosage and difficult flotation useful mineral particles can be fully recycled.

Simply by adding a small amount of inhibitor can be mixed concentrate flotation separation, the concentrate because this time there is no easy flotation of pyrite particles.For oxidation or partial oxidation of gold - copper ore, in addition to containing sulfide minerals in the ore also contains a large number of gold-bearing iron hydroxide and oxide copper minerals, more intractable type of ore, the best beneficiation and smelting joint process to be addressed.The first paragraph flotation recovery of the gold-bearing sulfide, and the second is used to recover the copper oxide and the surface film gold and wrapped in gold in the oxide,the third paragraph to recycle mineral surface in the acid leaching process has been cleansed copper and gold-bearing sulfides.
