通常人们只认为水玻璃是分散剂和抑制剂,实际在浮选过程中,水玻璃的某种添加量下,能使某此特定矿物的浮游性增加,又是活化剂。这一结论已在松树脚锡石多金属硫化矿浮选中得到证实,现将情况介绍如下。原矿性质松树脚锡石多金属硫化矿是以锡为主,伴生有黄铜矿,磁黄铁矿、黄铁矿、铁闪锌 Usually people only think that water glass is a dispersant and inhibitor, the actual flotation process, a certain amount of water glass added to make some of this particular minerals floating increase, but also activator. This conclusion has been confirmed in the flotation of pine foot cassiterite polymetallic sulfide ore, the situation is as follows. The nature of the ore pine foot cassiterite polymetallic sulfide ore is dominated by tin, accompanied by chalcopyrite, pyrrhotite, pyrite, iron sphalerite
