尼古拉耶夫斯基铜锌精矿处理困难。最适宜的方法是采用基夫赛特法,在基夫赛特炉的熔炼区产出冰铜,在电热区,则可从炉渣中蒸锌。为了处理这种物料,在额尔齐斯多金属公司建造了工业型基夫赛特试验炉。但由于能力不足和工艺技术掌握迟缓,必须试验其它方法来处理这种精矿,这就是沸腾焙烧法。 Nikolaevsky’s copper-zinc concentrates are difficult to handle. The most appropriate method is to use the Keffett method to produce matte in the smelting area of ​​the Keffett Furnace, where zinc can be distilled from the slag. In order to process this material, an industrial-type Kieffett pilot furnace was built at Irtysh Multimetal. However, due to lack of capacity and slow technology, we must test the other methods to deal with this concentrate, which is the boiling roasting method.
