一、绪言小坂厂月产电铜四千吨左右,并从铜电解的阳极泥中回收金、银、硒和碲。虽然过去提银车间搞了许多小改小革、但是阳极泥熔炼炉及分银炉仍是老式的,热效率和作业率较低;目前进厂铜矿中的含银量大幅度增加,银产量将增加一倍多,故需对提银车间进行全面的改造扩建。 I. INTRODUCTION The Kosaka plant produces about 400 tons of copper per month and recycles gold, silver, selenium and tellurium from the anode slime of copper electrolysis. Although the past silvermaking workshop engaged in many small change small leather, but the anode mud melting furnace and the silver furnace is still old, thermal efficiency and lower operating rates; the current into the copper plant into a substantial increase in silver content, silver production Will be more than doubled, it is necessary to carry out a comprehensive renovation of the silver lifting workshop expansion.
