Chapter 15: Flotation of CopperLeadZinc Ores ...

The copperleadzinc ores have an origin similar to copperzinc and leadzinc ores, the exception being those ores that contain copper, lead and zinc as the principal economic minerals. In addition, some of these ores contain significant amounts of precious metals and, more rarely, cobalt and nickel.

Flotation Reagents Collectors

Flotation Reagents Collectors. Froth flotation is the most widely used industrial process for the separation of finely liberated minerals. The process involves the aeration of minerals in water in the presence of flotation reagents which facilitate the attachment of air bubbles to and levitation of select minerals.

Copper Flotation

· Flotation of Copper Ores. In most plants engaged in the flotation of ores containing copperbearing sulphide minerals with or without pyrite, pine oil is employed as a frother with one of the xanthates or aerofloat reagents or a combination of two or more of them as the promoter. Lime is nearly always used for maintaining the alkalinity of the circuit and .

· The ore is mined from an open pit, crushed, and fed to ten ball mills. The concentrator is divided into two parallel comminutionflotation sections, so that five ball mills feed each flotation section. Both sections consist of three bulk copper and molybdenum rougher flotation lines, and the rougher concentrate is transferred to a regrinding stage.
