Lead and zinc mineral processing process in Shanxi
Lead and zinc mineral processing process :
Mining ores first by the jaw crusher preliminary broken, after broken to a reasonable fineness via the elevator or vibrating feeder evenly into the ball mill, the ball mill crushing, grinding ores. After ball mill grinding of ore fines into the next process: classification. Spiral classifier use different proportion of solid particles in the liquid precipitation rate of different principle of mixed ore washing, grading. Mineral particles are fed into the flotation machine, according to the different mineral characteristics to join different drugs, made to separate minerals and other substances.
Lead and zinc mineral processing case :
Some company's copper lead-zinc mine in Shanxi, the mine symbiotic relationship closely, and humidity particle size small, uses the original technology, copper lead concentrate containing excessive, affect the enterprise economic benefits. By improving the technology, chooses efficient equipment, good final index and standard reaches producing.
Because copper, lead content symbiotic relationship closely, complex ore properties, after a comprehensive analysis of ore properties, decided to adopt some new technology of selective flotation. First of all, on the basis of the original preferential flotation process, with good selectivity collector priority floating copper, get qualified copper concentrate, and then mixed flotation, to get to grind of the mixed concentrate separation, grinding fineness reach - 38 um 78 %, improve copper lead content of monomer dissociation degree, achieve copper lead ore separation conditions.
