Effective flotation collector reagent selection is dependent on the sulphide minerals present, their mineral associations in the ore, and circuit characteristics. Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance.

Froth flotation is a widely used separating technique for the recovery of Cu and Au in porphyry coppergold ores. In these ores, chalcopyrite and gold are the main valuable mineral/metal phases, with pyrite being the key sulphide gangue mineral. However, in these ores gold is mostly associated with pyrite rather than the copper minerals.

A sequential flotation process for the recovery of highgrade concentrates of copper, lead and cobaltnickel from sulfide ores is provided. A primary grind ore pulp is conditioned with SO 2 as H 2 SO 3 under intense aeration, and the conditioned pulp subjected to sequential flotation, with regrinding and conditioning of a copper rougher concentrate obtained in the first flotation step for copper.

Dec 20, 2018· The vast majority of polymetallic sulphide ores containing gold and silver are treated by this method. When flotation of such ores, gold and silver enter into the copper concentrate or lead concentrate closely associated with them. The products are called copper, gold and silver concentrate or lead, gold and silver concentrate, etc.

Flotation of Copper Ores. Treating coarser material or ores that contain a large percentage of heavy gangue (such as in the Coeur d'Alene), it has been found advantageous to increase this to as much as 4½ in. per foot to prevent the blanketing of the porous medium by coarse sand collecting on the bottom.
