加拿大Ni-Cu-Fe硫化矿,长期以来是世界上主要的鎳資源,然而銅-鎳难以分离。国际鎳公司(INCO)以浮选-磁选方法处理鎳冰銅,得硫化銅、硫化鎳和貴金属三个产品。这是分离銅鎳的成功的方法。冰銅分离方法很多,历来是应用化学方法分离。而国际鎳公司确立了机械分离方法。鎳高硫在模中从980℃徐徐冷却(七天),細磨后用五唑、戊基黄药和松根油、黑药等进行浮选。浮选获得78％
Ni-Cu-Fe sulphide ore in Canada has long been the world's major nickel resource, yet copper-nickel is difficult to separate. International Nickel Corporation (INCO) flotation - magnetic separation of nickel-matte copper, copper sulfide, nickel sulfide and precious metals three products. This is a successful method of separating copper and nickel. Many methods of separation of matte copper, has always been the separation of chemical methods. The international nickel company established a mechanical separation method. Nickel high sulfur in the mold from 980 ℃ cooling slowly (seven days), finely ground with pentazole, pentyl xanthate and pine root oil, black drug flotation. Flotation received 78%
