在多数镍厂里,高冰镍分离出的镍精矿处理流程如下:沸腾焙烧炉内《死烧》—回转窑部分还原—电炉还原熔炼。1973年,加拿大铜崖冶炼厂采用了高冰镍分离出的镍精矿在顶吹回转转炉处理的新方法。1967年苏联制定了从高冰镍分离出的镍精矿提取阴极镍的氧气—真空熔炼的新工艺,苏联诺里尔斯克镍联合企业目前已掌握了这种工艺。高冰镍分离出的镍精矿反射炉熔炼是一种氧气—真空熔炼的工艺。目前,各国的镍企业还没有用该原料在反射炉处理的经验。
In most nickel plants, nickel concentrate from high iced nickel is treated as follows: “dead burnt” in the roaster - partial reduction of the rotary kiln - smelting in an EAF. In 1973, the Canada Tongya Smelter adopted a new method for the treatment of nickel concentrate separated from high-ice nickel in the top-blow converter. In 1967, the Soviet Union formulated a new process for the oxygen-vacuum melting of nickel cathode from nickel concentrate separated from high-iced nickel. The technology was now mastered by the Union of Norilsk Nickel in the Soviet Union. Nickel concentrates isolated from high iced nickel Reflector furnace smelting is an oxygen-vacuum melting process. At present, the nickel enterprises in various countries do not have the experience of using this raw material in the reverberatory furnace.
