中文摘要:
      通过化学分析、光学显微镜观察、自动矿物分析仪(MLA)分析等手段,对云南某含银低品位铅锌矿进行了工艺矿物学研究。研究结果表明,矿石中可供选矿回收的有价元素为铅、锌及银;铅、锌主要以方铅矿、闪锌矿的形式存在;银少量以淡红银矿、浓红银矿、黝锑银矿等游离银矿物形式存在,但大量以微细包裹体或类质同象形式存在于铅矿物中;脉石矿物主要为石英,其次为绢云母、方解石、高岭土等。方铅矿及闪锌矿共生关系密切,交代结构突出、包裹关系复杂,导致矿物充分单体解离较困难;绢云母、高岭土等脉石矿物易泥化,会对浮选分离造成不利影响。
英文摘要:
      Detailed mineralogical characterization of a silver-containing lead-zinc ore in Yunnan province was carried out by using chemical analysis, microscopic observation, automatic mineral analyzers (MLA), etc. The results show that the recoverable metals include lead, zinc and silver. The lead and zinc in the ore mainly co-exist in the form of galena and sphalerite. A small quantity of silver exists in proustite, pyrargyrite, freibergite, etc., whereas more silver is hidden in isomorphic and plumbous mineral. The gangue mineral mainly consists of quartz, also of some sericite, calcite and kaolin. The galena and sphalerite are closely symbiotic with metasomatic texture and wrapped each other, which will lead to great difficulty in the mineral liberation of the ore. Sericite and kaolinite are also very apt to be slimed so as to produce adverse effects on the flotation separation.
