Abstract

The invention discloses a beneficiation method for recycling copper oxide lead-zinc ore with high mud content, high oxidation rate and high sulfur content. The beneficiation method comprises the following steps: sending crushed raw ore into an SABC crushing and grinding process system, and obtaining an ore grinding product by combining lime, H-08, isoamyl xanthate and ammonium dibutyl dithiophosphate which are put into a slurry pump pool; grading the ore grinding product through a cyclone, feeding the ore grinding product into a flotation process system, and roughing by combining sodium sulfide, sodium carbonate, ammonium sulfate, ethyl thio carbamate and terpenic oil which are put into the slurry pump pool; and carrying out four times of concentration on the roughed ore grinding product to obtain a bulk concentrate, and carrying out three times of scavenging to obtain tailings. According to the beneficiation method for recycling copper oxide lead-zinc ore with high mud content, high oxidation rate and high sulfur content, comprehensive recycling and utilization of the ore of the type can be achieved, and adverse effects on the environment are avoided.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, in particular to a mineral processing method for recovering copper oxide lead-zinc ore with high mud content, high oxidation rate and high sulfur content. Background technique [0002] An existing method of flotation of lead-zinc oxide ore is to grind the raw ore until the content of -0.074mm is in the range of 70% to 95%, and then perform mixed flotation of lead-zinc sulfide to obtain lead-zinc sulfide mixed concentrate Flotation separation is carried out in the lead-zinc separation process, which is separated from the main process. The lead-zinc sulfide beneficiation tailings are not deslimed and all enter the lead-zinc oxide flotation, the lead-zinc oxide ore sweeping concentrate and the beneficiation tailings are combined for separate flotation, and the flotation concentrate is returned to the beneficiation. This method eliminates the The effect of the flotation flotation agent ad...
