自从1969年芬兰的科科拉(kokkola)锌厂投产以来,奥托昆普已在几个扩产阶段中开发并拓展了焙烧、浸出、净液和电积等锌厂工艺,开发出了取代黄钾铁矾工艺的奥托昆普转化浸出工艺、基于砷的奥托昆普净液工艺和奥托昆普精矿直接浸出工艺等新工艺。自收购了挪威锌公司奥达厂和德国Oberursel的鲁奇冶金公司后,奥托昆普在焙烧、烟气净化、制酸和电积方面扩展了其技术诀窍。鲁奇冶金公司于1962年在印度第一次投入锌焙烧炉开始了其锌方面的商业运作,其后共有70多台鲁奇锌焙烧妒在世界各地投产。由于这些成绩。奥托昆普现在可以将目前的锌处理技术融合在一整套技术内。
Since the launch of the kokkola zinc plant in Finland in 1969, Outokumpu has developed and expanded zinc plant processes such as roasting, leaching, net liquor, and electrowinning in several expansion phases to develop and replace Outokumpu conversion leaching process of jarosite, Outokumpu arsenic-based net liquor process and Outokumpu concentrate direct leaching process and other new processes. Outokumpu has expanded its know-how in roasting, flue gas cleaning, acid production and electrowinning since the acquisition of Odda, a Norwegian zinc company, and Lurgi Metallurgical, Oberursel, Germany. Lurgi Metallurgical started its zinc operations in 1962 when it first entered the zinc roaster in India, followed by more than 70 Lurgi roasting jealousies operating around the world. Due to these grades. Outokumpu is now able to integrate current zinc treatment technologies into a complete suite of technologies.
