摘要
本文介绍了我国氧化铅锌矿资源的存在形式以及特点,详细评述了近年来国内外在硫化浮选方面的研究工作。硫化浮选过程中最关键步骤是硫化,其中硫化方法包括硫化-黄药法、机械硫化、硫化焙烧和水热硫化等,分析比较了这些方法的优缺点。生物硫化技术具备工艺简单、生产成本低、轻污染等优点,具有极大的发展潜力,有望成为矿物加工过程中的研究重点。
The present forms and features of oxided lead-zinc resources were described. Moreover,the researches of recent domestic vulcanization flotation were reviewed. The most crucial steps of sulfide flotation is vulcanization,including vulcanized-xanthate,mechanical vulcanization,vulcanization roasting and hydrothermal vulcanization and other curing methods. The advantages and disadvantages of these methods are compared and analyzed. Biological vulcanization technique has simple process,low production cost,light pollution and other advantages,and has a considerable development potential,which is expected to become the research emphasis in the course of mineral processing.
