脆硫铅锑矿冶炼工艺研发进展综述

A Review of Research and Development Progress on the Smelting Process of Jamesonite

脆硫铅锑矿是一种多金属复合硫化矿,一般的选矿技术很难将铅锑分离,常采用冶炼技术使其分离。自20世纪60年代以来,冶金工作者先后研发了多种工艺对铅锑进行分离,其中火法、氯化水解法和硫化钠浸出法等工艺投入了生产使用。随着冶炼技术的迅速发展,现有冶炼工艺不能满足当前需求,其局限性逐步显现。简述了脆硫铅锑矿的主要特点,针对氯化水解法、硫化钠浸出法和火法冶炼脆硫铅锑矿的工艺特点及存在问题,提出富氧强化熔炼法冶炼单铅矿及脆硫铅锑矿与单铅矿混合冶炼的最新工艺,指出今后应加强富氧强化熔炼工艺单独处理脆硫铅锑矿的研发力度。

Jamesonite is a kind of metal composite sulfide ore,and it is difficult to separate lead-antimony applying currently processing technology,instead, smelting technology is generally used for lead antimony separation.Since the 1960s,metallurgical researchers have developed a variety of crafts to separation of lead antimony, such as smelting, chlorization hydrolysis and sodium sulfide leaching method, etc.However, with the rapid development of smelting technology,the existing technologies can＇t meet today＇s development and the limitations gradually.In this review,we summarized the main characters of the jamesonite,then process characteristics and the existing problems of the mentioned methods were briefly addressed.Moreover, we analyzed the limitation of sulfur lead antimony smelting process, meanwhile, the oxygen-enriched strengthening smelting method of smelting single lead or single lead as well as brittle mixed lead antimony smelting sulfur latest technology were introduced.In addition,we mentioned that oxygen-enriched strengthening smelting process should be strengthened in the future.
