近五十年来主要采用的铅熔炼方法是烧结机、鼓风炉熔炼。1970年世界上用这种方法生产粗铅占80%,铅锌密闭鼓风炉的生产仅占8%,虽然鼓风炉炼铅已作了许多技术改进,但仍有许多缺点。最近几年来,出现了一些新的铅熔炼法,其中有一种是铅精矿一步炼成金属铅和渣的方法。氧化反应如下:
In the past 50 years, the main method of lead smelting is sintering machine, blast furnace smelting. In 1970, 80% of the crude lead was produced by this method in the world, and only 8% of the lead-zinc closed blast furnace was produced. Although many technical improvements have been made in blast furnace lead-ing, there are still many shortcomings. In recent years, a number of new lead smelting processes have emerged, one of which is the process by which lead concentrate is converted from lead concentrate to slag. Oxidation reaction is as follows:
