(1) The flotation of disseminated copper ore
Generally uses relatively simple flow, after the grinding,Cheap Jerseys Paypal, fineness – 200 mesh accounts for 50% ~ 70%,Wholesale Jerseys USA, 1 times rougher flotation,2 ~ 3 times purifying-flotation,Cheap NFL Jerseys Outlet, 1 ~ 2 times scavenging. If the disseminated granularity of copper ore is finer, we can consider using stage grinding process. When handle bornite dressing plant the most process used is to grind rough concentrate, use grinding flotation in purifying-flotation tage, its essence is mixed – preferential floatation process. After a rough grinding,Wholesale Authentic Jerseys, rougher flotation, scavenging, and then make rough concentrate to grind and re-purifying flotation to get high grade copper concentrate and sulphur concentrate. Coarse grinding fineness – 200 meshes is about 45% ~ 50%, grinding fineness – 200 meshes is about 90% ~ 95%.
(2) The flotation of dense copper ore
About dense copper ore, because chalcopyrite and pyrite are dense symbiosis, pyrite often is activated by secondary copper mine,NFL Jerseys Supply, pyrite content is high so it is difficult to restrain and separate. Separation process requests to get copper concentrate and sulphur concentrate at the same time. Usually the tailings after copper ore flotation is the sulfur concentrate. If the gangue minerals content in ore exceeds 20% to 25%, it still needs to make separation again for getting sulfur concentrate. For treating density copper ore,Cheap NFL Jerseys China, it often uses two stages grinding or stage grinding, the grinding fineness requires fine. Reagent dosage is also larger, the dosage of yellow catching agent is above 100g/ (ton raw ore), lime is above 8 ~ 10kg (ton raw ore).
