Direct Alkali Smelting Process of Pb-Bi-Ag Sulfide Ore

研究采用火法 湿法联合工艺处理铅铋银硫化矿 ,综合回收有价金属。铅铋银硫化矿直接碱法熔炼 ,分别处理产出的铅铋合金、浮渣和冰铜 ,回收铅、铋、银、铜、钼、锌等。“火法 湿法联合流程”适宜于铅、铋、贵金属及稀散金属的混合硫化矿 ,有价金属的综合回收效果良好。该方法对环境无污染 ,能耗和原材料消耗少 ,金属综合回收率高 。

The treatment of Pb Bi Ag sulfide ore and recovery of valuable metals with the corporation of pyro and hydro metallurgical process are investigated. The Pb Bi Ag sulfide ore is directly smelted by use of alkali process in a reverberatory furnace, and the products, i.e. Pb Bi alloy, slag, and matte, are treated respectively to recover lead, bismuth, silver, copper, molybdenum, zinc etc. This technology is adapted to the mixed ore of lead, bismuth, precious and rare metals, and effective for comprehensive recovery of metals in the ore. It is clean production technology with no pollution on environment, low energy consumption, less auxiliary materials exhaust, and high recovery of metals.
