Copper sulphide flotation processes and equipment
The copper sulphide is one of the main type of copper. The deposits are mostly copper pyrite deposits and copper skarn deposits, widely distributed.
Flotation copper Sulfur. Generally the first floating copper, then float sulfur. Dense massive copper pyrite ore pyrite content is quite high, often with high alkalinity, its tailings is pyrite gangue, tailings is sulfur concentrate. Disseminated copper and sulfur copper ore production process, floating copper tailings again floating sulfur, in order to reduce the floating sulfur, sulfuric acid consumption and to ensure the safe operation of floating copper, as far as possible the conditions of low alkalinity.
Mixed – flotation separation of copper sulphide. Lower ore sulfur, copper and sulfur ore of copper minerals easy to float prefer to use this process is more advantageous. Copper sulfide minerals is the first in a weak alkaline pulp mixed flotation, mixed concentrate is combined with lime in the high alkaline slurry separation flotation of copper concentrator plant.
Half of the priority mixed – flotation separation of copper sulphide. Priority mixed flotation separation first surfaced easy to float the copper minerals, partially qualified copper concentrate, and then the flotation of copper and sulfur, sulfur mixed concentrate of copper obtained using floating copper suppression of sulfur flotation separation. This separation method the flotation of copper sulphide process, to avoid the inhibition of copper minerals in easy to float in the high lime dosage, copper ore processing plant. Production practices: this process is a reasonable structure, stable operation, good indicators of characteristics with the purpose of mineral recovery as soon as possible.
In addition, it is worth noting that two kinds of copper mineralized dense massive copper pyrite and disseminated copper pyrite. Former high content of pyrite, the latter pyrite content is low. Flotation of this ore in addition to recovery of copper sulfide, but also the recovery of the iron sulfide as a sulfur concentrate.
