Disseminated state The flotation of copper ore generally adopts a relatively simple process. After a stage of grinding, the fineness mesh accounts for about %~%, a second rough separation, a second fine selection, and a second sweep. If the dispersion particle size of copper minerals is relatively fine, the staged grinding process can be considered. Most of the concentrators that process bornite use a staged grinding process of coarse concentrate regrinding & beneficiation, which is essentially a mixing & priority flotation process. After a period of coarse grinding, rough selection and sweeping, the coarse concentrate is then ground again and then refined to obtain high-grade copper concentrate and sulfur concentrate. The coarse grinding fineness mesh accounts for about %~%, and the regrinding fineness mesh accounts for about %~%.
Flotation of dense copper ore. Due to the dense symbiosis of chalcopyrite and pyrite, pyrite is often activated by secondary copper minerals. The pyrite content is high and difficult to suppress and sort. difficulty. During the sorting process, copper concentrate and sulfur concentrate are required to be obtained at the same time. Usually the tailings after copper beneficiation are sulfur concentrates. If the gangue content in the ore exceeds %~%, it needs to be sorted again to obtain the sulfur concentrate. To process dense copper ore, two-stage grinding or stage grinding is often used, and the grinding fineness is required to be fine. The dosage of the agent is also relatively large, the dosage of yellow is more than (raw ore), and the dosage of lime is more than (raw ore).
