60 centuries of copper: the flotation process

The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the

sulphidation of copper oxide ores for flotation

The flotation of copper oxide ore includes direct flotation and indirect flotation. Direct flotation is mainly used to treat copper oxide ores with simple mineral composition and uncomplicated properties indirect flotation is to sulfide copper oxide ores by adding sulphide agent and then flotation with common sulphide flotation agent.

effect of pulp potential on the flotation of a sulfide

Sulfidization requires pulp potential control to keep this parameter in the range of 0 to +100 mV, yielding high copper recoveries at minimum collector (90 git) and fr other (60 git) dosages. Flotation with nitrogen reduces the sodium sulfide dosages required to keep the pulp potential within the optimum range

mining industry | copper sulfide ore and flotation process

1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite

the different effects of bentonite and kaolin on copper

Recently, it has been reported that the addition of 25% kaolinite has caused the flotation grade of a copper ore to be reduced from 4% to 1.5% (about 60% reduction) (Wang et al., 2015) (although

lime use and functionality in sulphide mineral flotation

Nov 01, 2019 · At Silver Queen mine (Canada) a combined lime-starch-SO 2 conditioning scheme is used for copper flotation from the Pb/Zn sulphides (Bulatovic, 2007b). In the process, lime (1200 g/t) and starch (200 g/t) are used first, at pH 10.5–11.2, after which the pH is reduced to 5.5 with SO 2 (200 g/t) and the copper sulphide floated
