Abstract

The invention relates to a beneficiation process for obtaining independent copper and zinc concentrate from low-copper high-zinc sulfide ore. The beneficiation process comprises the following steps of step 1, grinding raw ore to obtain a mixture which can be used for flotation; step 2, performing copper roughing and copper scavenging on the mixture which can be used for flotation, and obtaining copper rough concentrate and copper scavenging tailings; step 3, concentrating the copper rough concentrate, regrinding concentrated underflow obtained after concentration, and obtaining a copper-zinc mixture; step 4, subjecting the copper-zinc mixture to separation roughing, separation concentration I, separation concentration II, separation scavenging I and separation scavenging II through a separation device, where foam of separation concentration II is copper concentrate; and step 5, combining the copper scavenging tailings and the copper concentrate and subjecting the same to zinc roughing, zinc concentration I, zinc concentration II, zinc concentration III, zinc scavenging I and zinc scavenging II through a flotation machine, where foams of zinc concentration III are zinc concentrate. Therefore, the copper-zinc separation effect can be remarkably enhanced, and consumption of conventional inhibitors zinc sulfate and sodium sulfite is reduced.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a mineral processing process for obtaining independent copper and zinc concentrates from low-copper and high-zinc sulfide ores. Background technique [0002] The separation of copper and zinc is a key and difficult point in the flotation research of sulfide ores. Copper sulfide ore is theoretically easier to float than sphalerite, but sphalerite is easily activated by Cu2+ dissolved from copper sulfide ore, which makes the separation of the two difficult. . In the early separation of copper and zinc, cyanide was mostly used to inhibit sphalerite. The principle is that cyanide complexes Cu2+ and removes its activation of sphalerite. Although the effect of cyanide is good, it brings serious environmental pollution and safety. Hidden danger. [0003] At present, the widely used copper-zinc separation agent is the combined inhibitor of zinc sulfate and sodium sulfite, bu...
