铅锌鼓风炉熔炼法原来主要用于处理原生铅锌精矿,目前认识到该法还具有可以处理更为广泛的物料的能力。越来越多的复杂的混合料以及冶金工业或其他工业的残渣(其中有此残渣会污染环境)混在炉料内进行熔炼,从而可以回收其中有价金属和安全处理有害元素。这些物料包括电解锌厂的含银铅浸出渣,炼铅厂的烟尘,炼钢厂的烟尘和再生锌灰,以及低品位含铜精矿。以下两项技术的发展更为扩大铅锌鼓风炉处理炉料范围提供了可能性。
Lead-zinc blast furnace smelting process was originally used to deal with the primary lead-zinc concentrate, now recognized that the law also has the ability to handle a wider range of materials. More and more complex mixes, as well as residues from the metallurgical industry or other industries where the residue can pollute the environment, are mixed in the charge and smelted to recover valuable metals therein and to safely handle hazardous elements. These include lead-lean silver-containing leachates from electrolytic zinc mills, soot from smelters, soot and regenerated zinc ash from steel mills, and low-grade copper-bearing concentrates. The development of the following two technologies has made it possible to further expand the charge range of lead zinc blast furnaces.
