无机磷酸盐的化学和物理——化学性质决定着它们在浮选时的作用是各种各样的.(有关缩合磷酸盐的抑制作用具有许多报导),例如,六聚偏磷酸钠抑制脉石矿物,磷酸三钠抑制硫化铜矿和硫化铁矿,据报导,六聚偏磷酸钠使方铅矿疏水,可清洗黄铁矿表面,除去钙质薄膜,而磷酸二氢盐则活化黄铁矿。在上述文献中也注意到磷酸盐的下述能力:(1)降低矿浆中有害许多矿物浮选
The chemical and physico-chemical properties of inorganic phosphates determine their role in flotation. (There are many reports about the inhibitory effects of condensed phosphates.) For example, sodium hexametaphosphate suppresses gangue Minerals, trisodium phosphate suppresses copper sulphide and iron sulphide. It is reported that sodium hexametaphosphate is hydrophobic to galena, which cleans pyrite surfaces to remove calcareous films while dihydrogen phosphate activates pyrite . The following capabilities of phosphates have also been noted in the above references: (1) to reduce the deleterious effects of many mineral flotation
