曾提出用返回水提高了锌矿物的浮游活性。列宁格勒选矿厂在用返回水条件下选择铜锌矿石浮选药剂制度,以探讨对锌矿物的抑制。以在苏打介质中用硫酸钠配合少量氰化物,在苏打介质中用硫酸亚铁与亚硫酸钠配合硫酸锌、石灰;亚硫酸钠与硫化钠配合硫酸锌、水玻璃;在石灰介质中用亚硫酸钠配合石灰、亚硫酸钠、硫化钠作为闪锌矿抑制剂时,铜精矿中锌的损失都不少于50％。探讨了在苏打介质中用硫酸锌、氰化物、
It has been proposed to use the return water to increase the zooplankton activity of zinc minerals. The Leningrad beneficiation plant chose the copper-zinc ore flotation reagent system under return water conditions to explore the inhibition of zinc minerals. In the soda medium with sodium cyanate with a small amount of cyanide in the soda medium with ferrous sulfate and sodium sulfite with zinc sulfate, lime; sodium sulfite and sodium sulfide with zinc sulfate, sodium silicate; lime in the lime with sodium sulfite, sodium sulfite , Sodium sulfide as a sphalerite inhibitor, the loss of zinc in copper concentrate are not less than 50%. Discussed in the soda medium with zinc sulfate, cyanide,
