南京铅锌银矿,自1970年建立选矿厂以来,由于地理、地形条件的限制,无法建立尾砂坝,浮选尾矿排放长江,造成公害。针对尾矿的处理进行试验,确定尾矿中+37微米粗粒级返回井下充填,-37微米细粒级经浓缩、过滤,加水泥成块后再返回井下充填。而细粒级尾矿因浓度稀,粒度细,粘度大,常用的真空过滤是无法过滤,所以决定将细粒尾矿进行压滤机试验。1985年9月我
Nanjing Lead-Zinc-Silver Mine. Since the founding of the ore dressing plant in 1970, tailings dams can not be established because of the geographical and topographical conditions, and flotation tailings discharge into the Yangtze River causing pollution. Tailings for the treatment of the test to determine the tailings +37 micron coarse grade back downhole filling, -37 micron fine grade by the concentration, filtration, cement and then back into the downhole filling. The fine-grained tailings due to the concentration of thin, fine particle size, viscosity, the commonly used vacuum filtration is unable to filter, it was decided to fine-grained tailings filter press test.
