Embodiment 1
[0037] This embodiment provides a clean and efficient beneficiation method for complex gold-silver-containing copper-lead-zinc composite ore, such as figure 1 shown, including the following steps:
[0038] S1. Three-stage grinding-Nelson pre-selection gold-copper-lead mixed flotation:
[0039] The finely crushed raw ore (ore particle size -16mm) is sent to the first-stage ball mill by the belt conveyor for grinding, and the discharge of the first-stage ball mill is fed into the first-stage cyclone for inspection and classification. It is planned to send half of it from the slurry distribution pipeline into the second-stage cyclone for pre-grading, and the other half returns to the first-stage ball mill for continuous grinding; The discharge of the ball mill is returned to the second-stage cyclone for inspection and classification. The overflow obtained after the classification of the first-stage cyclone and the second-stage cyclone is sent to the third-stage cyclone for pre-g...
Embodiment 2
[0058] The Kizil-Tashtek polymetallic ore in the Republic of Tuva, Russia is a rare high-quality super large composite sulfide ore containing gold, silver, copper, lead and zinc. There are many kinds of minerals in this mine, the symbiotic relationship between minerals is close and complex, and the embedded particle size is fine, so it is difficult to select and smelt. For the raw ore randomly taken at different times and places in the mining area, the raw ore used in this example contains 8.02%, 1.51% zinc, 0.64% copper, 1.54g / t gold and 72.24g / t silver.
[0059] (A) Three-stage grinding-Nelson pre-selection gold-copper-lead mixed flotation:
[0060] The finely crushed raw ore (ore particle size -16mm) is fed into the first-stage ball mill by the belt conveyor for grinding, and the first-stage ball mill is discharged into the first-stage cyclone for inspection and classification. Quality meter) is fed into the second-stage cyclone by the pulp distribution pipeline for pre-gr...
Embodiment 3
[0073] The raw ore used in this example contains 9.92% zinc, 1.67% lead, 0.73% copper, 1.67g / t gold and 80.74g / t silver.
[0074] (A) Three-stage grinding-Nelson pre-selection gold-copper-lead mixed flotation:
[0075] The finely crushed raw ore (ore particle size -16mm) is fed into the first section of ball mill by belt conveyor for grinding, and the first section of ball mill is fed into the first section of cyclone for inspection and classification. total) is fed into the second-stage cyclone by the pulp distribution pipeline for pre-grading, and the other half is returned to the first-stage ball mill to continue grinding; the grit classified by the second-stage cyclone is fed into the second-stage ball mill for grinding, The discharge returns to the second-stage cyclone for inspection and classification, and the graded overflow of the first-stage and second-stage cyclones is fed into the third-stage cyclone for pre-grading;
[0076] The grit classified by the three-stage ...
