会泽铅锌矿冶炼入炉原料之一为矿山厂的氧化脉矿。矿石由索道运输入破碎筛分厂破碎至-8m/m以后入冶炼厂。现行冶炼工艺流程是:原矿由鼓风炉熔化,经烟化炉挥发产出烟尘。烟尘用硫酸浸出,浸出渣返回配料系统,浸出液加丹宁沉淀锗。沉淀物经干燥、灼烧、蒸馏、水解、还原铸锭得粗锗。溶液净化后电解,熔铸得锌锭。经过近年生产实践,以上生产流程存在几个问题:
Huize lead-zinc smelting furnace into one of the raw materials for the mine oxide veins. Ore from the ropeway into the crushing and screening plant broken to -8m / m into the smelter. The current smelting process is: the ore is melted by the blast furnace, and the fumes are volatilized and produced by the fuming furnace. Soot leaching with sulfuric acid, leaching residue back to the batching system, leaching solution plus tannin precipitated germanium. Precipitate by drying, burning, distillation, hydrolysis, reducing ingot rough germanium. After the solution electrolysis electrolysis, casting cast zinc ingots. After the production practice in recent years, there are several problems in the above production process:
