随着工业的迅猛发展,对铜镍等有色金属的需要量逐年增加,能直接冶炼的富矿或易选的硫化矿开采量日益减少,大量低品位、难选的氧化矿和含有多种有益组分需综合利用的矿石有待开发利用。由于这些矿石矿物组成和化学成分复杂,用一般的机械选矿方法难以富集。因而,大大促进了其他方法的试验研究。 With the rapid development of industry, the demand for non-ferrous metals such as copper and nickel is increasing year by year. The amount of mined or optionally sulfided ore that can be directly smelt is declining. A large number of low-grade and refractory oxidized mines and a variety of beneficial minerals The comprehensive utilization of ore needs to be developed and utilized. Due to the complex mineral composition and chemical composition of these ores, it is difficult to enrich them with the usual mechanical beneficiation methods. Thus, the experimental research of other methods has been greatly facilitated.
