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

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.
