(1) The flotation of disseminated copper ore,Tampa Bay Buccaneers jerseys
Generally uses relatively simple flow, after the grinding, fineness – 200 mesh accounts for 50% ~ 70%, 1 times rougher flotation,2 ~ 3 times purifying-flotation,Calgary Flames jerseys, 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,Colorado jerseys, rougher flotation, scavenging,Philadelphia 76ers jerseys, 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,Denver Broncos jerseys, because chalcopyrite and pyrite are dense symbiosis, pyrite often is activated by secondary copper mine,Milwaukee Brewers jerseys, 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, 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),Milwaukee Brewers jerseys, lime is above 8 ~ 10kg (ton raw ore).
