Features and Flotation of Complex CuPbZn Sulphides

Abstract Problems arising during flotation of complex CuPbZn sulphide ores are in general of geological origin. The features of these ores are reviewed, stressing that mineralogical studies extending to process mineralogy are prerequisite for a consistent flotation process. Some examples affecting flotation are given.

90% of nonferrous metal ores (copper, lead, zinc, etc.) adopt flotation process, especially for those with fine grain and complex symbiosis. 90% of nonferrous metal ores (copper, lead, zinc, etc.) adopt flotation process, especially for those with fine grain and complex symbiosis. Xinhai CuPbZn Ore flotation processes.

Copper Lead Concentrate Separation

The separation of copperbearing from zinc sulphides is effected by twostage selective flotation, the zinc minerals being depressed and the copper minerals brought up in the first stage with reagents similar to those required in the lead flotation section of a leadzinc plant; the zinc sulphides are floated in the second stage in the ordinary way. The ores treated by this process are mainly those containing

Copper Mineral, Extraction of Zinc, Extraction of Copper

According to ore properties and a series of processing tests, Xinhai finally decided copper and lead mixed flotation separation mixed tailings zinc flotationflotation tailings weak magnetic separation process, so the plant also get more than 65% iron

Effect of carbon on Cu/Pb/Zn flotation. Froth Flotation

It's understood that separation of carbon in PbZnCu ore is either done by depression with suitable surface coatings (Nigrocene or similar chemical) or with pre flotation option, which depends upon the flotation kinematics of geological species in ore population and the quantum of carbon present.

pH Ranges for Sequential Cu Pb Zn Flotation Separation

As MBS is added and pH drops from Natural pH 9, other minerals are depressed is this order Iron (pyrite) Zinc. Lead. Copper (Chalcopyrite and others) As Lime is added and rises pH towards 12, depressed again is Iron (pyrite), followed by Zinc. ** Activated Zinc, in the Cu and/or Pb Circuit, will float like Copper.

CuPbZn, CopperLeadZinc Ores, Copper Lead Zinc

In general, the most difficulty of the polymetallic sulfide ores separation is the separation among several kinds of ores, especially those lowgraded ores with complex embedded features. Therefore, its a significant step for separating leadzinc, copperzinc, copperlead to choose right flotation reagents.

Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
