有关矿山曾采用几种型式的馬弗炉和蒸餾炉处理汞精矿,冶炼回收率都取得了良好指标,在98％以上,但在热工和炉型結构(加料、排渣和密封)等方面不够理想,不能满足工艺要求。1965年初,我們协同有关单位,采用电热廻轉管状蒸馏炉进行了处理汞精矿的弑驗,結果表明:不仅回收率可稳定在99％以上,而且炉型結构简单,控制特别简便。原有 Mining mines have used several types of muffle furnaces and distillation furnaces for the treatment of mercury concentrates, smelting recovery rates have achieved good indicators, at 98%, but in the thermal and furnace structure (feeding, slagging and sealing), etc. Not ideal enough, can not meet the technical requirements. In early 1965, we collaborated with the relevant agencies to conduct experiments on mercury concentrates using a rotary kiln. The results show that not only the recovery rate can be stabilized at over 99%, but also the furnace structure is simple and the control is particularly convenient. original
