在调查了配料、烧结和熔炼各工序存在问题基础上,进行了技术改造。取得精矿品位比设计值低,而产量仍达到5000t/月设计能力、渣含铅低到3%以下的好指标。
On the basis of investigation of the existing problems in the ingredients, sintering and smelting processes, the technical transformation was carried out. To obtain the concentrate grade lower than the design value, and the output is still up to 5000t / month design capacity, low lead content of 3% below the good indicator.
