对多金属矿的铜铅分离浮选,选用 Na_2SiO_3等组合药剂替代 K_2Cr_2O7,不仅排除了高铬离子尾矿水对环境水源的污染,而且取得了较好的铜铅分选技术经济指标。
For the copper-lead separation and flotation of polymetallic ores, the combination of K 2 Cr 2 O 7 instead of K 2 Cr 2 O 7 is not only excluded from the pollutions of environmental water sources by the tailings of high-chromium ions, but also achieved good technical indexes of copper and lead sorting.
