Mineral Processing

Copper ore flotation

Mineral Introduction1.Industrial of copper ore: There are more than 280 kinds of copper-bearing minerals found in nature, mainly including more than 20 kinds, mostly produced in the form of sulfides and similar compounds, oxides, natural copper and its copper sulfates and silicates. The copper ore is mainly sulfide minerals with the theme of brass, copper, copper and azurite. With the improvement of mineral processing technology, the mining and ore dressing ratio for oxidized ore is gradually increasing. Almost all ore and sulfide minerals in the mine coexist, and the mineral processing value and process are determined when a certain mineral is the main component.

Common Mineral Processing Methods2.Common processing method: flotation

Mineral Type

3.Deposit type: A. Marine volcanic rock ore: Pyrite-type copper ore, mainly composed of brass pyrite, with a grade of about 1%. It is a sulfide ore and is an easy-selected deposit. B. Melting-off copper-nickel ore ultrabasic rock: mainly chalcopyrite and nickel pyrite, with a grade below 1%. C. Layered metamorphic rock ore: mainly brass and copper, grade greater than 1%, belonging to sulfide ore. D. skarn type ore: mainly copper, followed by copper, brass , its grade is greater than 1%, is a sulfide ore, easy to choose; E, porphyry ore: mainly brass, followed by spot copper, copper, grade less than 1%. F. other types of deposit: iron , sulphur, lead and zinc, gold and silver associated with symbiotic ores.
