How Is Concentration Of Copper Ore Froth Flotated

The ore is a sulfide copper ore containing heads of approximately copper 0.45, iron 3.4, molybdenum 0.006, and zinc 0.06 per ore sample. Prior flotation of this ore has employed, in the floation cell, the addition of pine oil as required to optimize froth, ordinarily resulting in a total pine oil concentration of about 0.24 lb. ton.

Copper Ore

Copper ore usually contains about 0.5 to 2% copper that occurs in the form of disseminated and stringers. The run of mine ore is reduced from 150 mm to 25 mm size in Jaw and Cone crushers. The crushed ore is grinded in ball mills to −74 μm size. The ore is processed by froth flotation comprising rougher and scavenger cells.

Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and u…
