用中等到较高品位的硫化锑精矿在半工业试备进行旋涡炉挥发法试验得到了令人鼓午的结果,因此对这个方法的优点以及它对炼锑厂整个工艺流程的影响,作了更详细的研究,提出的任务是在玻利维亚建设一个工艺流程最佳、年产能力约6,000吨锑的炼锑厂。按该厂所处地区,应处理富的、杂质相当低的浮选精矿。但该厂应有足够的机动性,以便今后需要减少金(尸专)锑的产(旦力)时,也可以处理含铜或含贵金(尸专)的中等品位的锑精矿。
The use of intermediate-to-high grade antimony sulfide concentrate in a pilot test of vortex furnace volatility obtained encouraging results and therefore the advantages of this method and its impact on the entire process of refining the antimony plant, For a more detailed study, the task proposed was to build an antimony plant in Bolivia with the best process and an annual capacity of about 6,000 tons of antimony. According to the plant in the area, should deal with the rich, very low impurity flotation concentrate. However, the plant should be sufficiently maneuverable so that it may be possible to dispose of medium-grade antimony concentrates containing copper or precious metal (necropsy) when it is necessary to reduce the production of gold (antimony) in the future.
