1984 beneficiation plant power consumption is 63.03kw.h / t, where the crushing 2.53kw.h / t, mill floating 51.35kw.h / t, dewatering, water supply and drainage, tailings 8.97kw.h / t.
The coarse crushing is carried out in the underground. After the coarsely crushed product is lifted to the ground, it is transferred to the concentrating plant by the aerial ropeway. The plant is only set in medium and fine crushing operations. Grinding is stage grinding, stage selection, the first and second sections are series grinding, and lime is added in the ball mill to ensure that the PH value is greater than 11 for rough lead selection. The third paragraph is the re-grinding of the crude lead concentrate. Since the ore processed by the plant is not sensitive to cyanide and the amount of cyanide is not added or affected, it has little effect on the concentrate grade and recovery rate. Therefore, the plant has eliminated cyanide and used zinc sulfate and lime as inhibitors.
The process indicators of the concentrator, unit consumption indicators and main equipment are shown in the following table:
