中国铅锌冶金技术状况及发展趋势:锌冶金

Lead and zinc metallurgy technology situation and development treads of China:zinc metallurgy

近10多年来,世界铅、锌精矿和铅、锌生产量的增量主要来自中国,中国已经成为名副其实的世界铅、锌加工国,并由此带来巨大的资源和环境压力.文中在系统介绍和总结中国铅、锌冶炼技术发展状况、各自技术特点和适应性的基础上,探讨中国铅、锌冶金工业技术发展中存在的主要问题和应关注的发展方向.从消费结构分析,未来我国铅的生产必然会转向以再生铅为主的格局,但锌的生产依然会以原生锌生产为主,如何在原生铅生产过程中实现每年数百万吨新增锌冶炼渣的无害化处置,必须引起我们的重视.

In the recent decade, China mainly contributed the worldwide production and increase of lead and zinc, such that China became a veritable lead and zinc producer, which results in huge resource and environment burdens.In this article, main issues and development existing in China’s lead and zinc processing technologies in the metallurgy industry were discussed, based on systematic introduction and summarization of the situation,development, characteristic and adaptability of these technologies.Given the consumption structure, the raw material for lead production will mainly originate from secondary lead-bearing materials, while that for zinc production will still originate from raw ores.Thus, millions of tons of zinc-containing slags will annually generate during processing raw lead-bearing ores.Notably, the innocent treatment of these slags should be worth considering.
