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 metal in finely disseminated particles which aggregateОнлайн-запрос

Flotation is made from finely ground copper ore in flotation cells. The previous page explains the types of copper ore that exist and the extraction process that results in finely ground copper ores. The production of Cu-rich sulfide concentrate (~30% Cu) is described here. The grinding step is crucial because it leads to very fine particles of about 1 mm in diameter.

Mining Industry | Copper Sulfide Ore and Flotation

3 Summary of the copper mineral flotation process (1) Copper minerals (such as chalcopyrite and covellite) that do not contain iron are similar in floatability. Cyanide and lime have weaker inhibition on them, so a large amount of lime can be added to inhibit pyrite in the separation of copper and sulfur without seriously affecting the floatability of copper minerals. (2) The copper mineralsОнлайн-запрос

Copper extraction Wikipedia

Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide (usually chalcocite), which can then be activated by the froth flotation plant.Онлайн-запрос

In the copper-sulfur separation operation, due to the large amount of lime and the fine grinding particle size, it has a greater impact on the corresponding flotation of molybdenite; in the actual copper separation operation, the copper recovery rate is only ≤50 %. For some of these ores, the overall recovery rate is only 80% because of the relatively low grade of molybdenum in the original ore.Онлайн-запрос
