flotation process Copper ore production line 

(1) disseminated copper ore flotation

Grenerally use relatively simple process, through a grinding fineness-200 mesh about 50% to 70%, 1 roughing,2 or 3 times selected, 1 or 2 times sweep the election. Comparison of disseminated copper minerals, such as samll size, may consider the stage of grinding and separatino process. Treatment spot copper concentrator, mostly coarse concentrate regrinding-a selection of stage grinding and  separation proceses, and its essence is mixed-flotation process. First through a coarse grinding, roughing, savenging jaw crusher and then rough concentrate. Coarse Ground degrees-200 mesh about 90% to 95%

(2)dense compact copper ore copper ore flotation machine chalcopyrite and pyrite as tight symbiosis, pyrite is often of secondary copper-activated pyrite content is high, difficult to inhibit the separation difficult. Sorting process required by copper concentrate and concentrate at the same time. Usually after the election of copper tailings is pyrite concentrate. If the ore gangue content of more the 20% to 25%, sulfur concentrate needed to get re-sorting ball mill. Densse copper ore processing, often using two stages of grinding or grinding, girinding fineness requirements smaller. Als larger amount of reagent, xanthate dosage 100g(t ore), lime 8-10kg(t ore) above.
