氟硅酸钠是浮选黑钨细泥和锡石细泥广泛使用的调整剂。甲烷基硫酸钠、A-22、苯乙烯磷酸浮选锡石细泥时,矿浆中的Cu~(2+)、Fe~(3+)等离子对锡石有抑制作用,加入氟硅酸钠能扩大浮选区域,对锡石有活化作用。用磷酸、A-22浮选锡石时,用氟硅酸钠作抑制剂抑制脉石。用A-22、磷酸、砷酸浮选黑钨矿时,氟硅酸钠都是有效的抑制剂。在浮选钛铁矿时,氟硅酸钠可作为抑制剂抑制脉石。
Sodium fluorosilicate is a widely used regulator of flotation black tungsten fine slime and cassiterite. When sodium methanolate, A-22 and styrene phosphoric acid float flotation cassiterite, the Cu 2+ and Fe 3+ in the pulp inhibited the cassiterite, and sodium fluosilicate Expand the flotation area, activation of cassiterite. With phosphoric acid, A-22 flotation cassiterite, with sodium fluoride as an inhibitor to suppress gangue. With A-22, phosphoric acid, arsenic flotation wolframite, sodium fluoride are effective inhibitors. In the flotation of ilmenite, sodium fluoride can inhibit gangue as an inhibitor.
