In September 1977, the Pengxian Copper Mine used butyl ammonium blacks, reducing not only the types of chemicals from seven to five, the medicament costs by 54.8%, the ore processing fees by 26.2% (60.3% less than the design), and beneficiation Technical indicators have increased. First, the nature of ore and production profile Selected ore Department of dense disseminated copper-zinc pyrite, the main minerals pyrite (accounting for 32.87% of ore, embedded grain size 0.25 ~ 0.33 mm), chalcopyrite (accounting for 1.65 %, Embedded particle size of 0.02 to 0.05 mm), flash
