The concentrate is dehydrated in two stages, and the final concentrate contains water: lead 11~12%, zinc 12.5%, sulfur 12%.
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:

As the name implies, Round Molded Graphiteis a cylindrical product of graphite electrode, which is made of graphite block materials by crushing, screening, batching, shaping, cooling, roasting, dipping and graphitization of post section petroleum coke and medium temperature coal tar pitch. It has the advantages of high temperature resistance, corrosion resistance, good conductivity and light weight. It is mainly used for large DC resistance furnaces, blast furnace bricks, conductive electrodes, lining anti-corrosion and other purposes.
The high-purity graphite, graphite block and Molded Graphite produced by Pingdingshan Carbon Graphite Factory for many years are excellent, and the specifications of Round Molded Graphite are as follows: φ 450*800, φ 520*400 φ 630*420, φ 660*620 φ 780*600, φ 820*350~500 φ 900*350~400, φ 1050*350~400 φ 980~350*400, φ 1160*350~680 φ 1260*350~680, φ 1330*400 φ 1420*400, φ 1520*400 φ 1630*350, φ 1800*350 φ 2000*350, φ 520~2000*680
