奥托昆普公司曾开发了高效火法冶金闪速熔炼技术,在溶剂萃取湿法冶金方面近来也取得了重大进展。奥托昆普VSF溶剂萃取工艺不仅效率高,而且投资少,生产成本低。其显著优点是:碱性有机溶液量比常规设备少20%; ·萃取液杂质含量低, ’电解液过滤要求不严。·设备体积小; ·有机溶剂耗量少; ·设备简 Outokumpu has developed efficient pyrometallurgical flash smelting technology and has made significant strides recently in solvent extraction hydrometallurgy. Outokumpu’s VSF solvent extraction process is not only efficient, but also low-cost and low-cost. The significant advantages are: the amount of alkaline organic solution 20% less than conventional equipment; * low impurity content of the extract, ’strict electrolyte filtration requirements. · Small equipment size; · less organic solvent consumption; · equipment is simple
