生产有色金属、稀有金属和贵金属,都要经过选矿,而所用的主要选矿方法是浮选。仅在有色金属企业每年就要浮选上亿吨的矿石。且只有在广泛应用表面活性物质的条件下,才能顺利地进行浮选,所用的表面活性物质即是起不同作用的各种浮选药剂其中捕收剂和起泡剂起着特别重要的作用。 Production of non-ferrous metals, rare metals and precious metals goes through beneficiation, and the main beneficiation method used is flotation. Only in the non-ferrous metals enterprises flotation of hundreds of millions of tons of ore each year. The flotation is carried out smoothly only under the condition of extensive application of surface-active substances, and the surface-active substances used are various flotation agents with different functions. Among them, collectors and foaming agents play a very important role.
