介绍了邵东铅锌矿从分选出铅锌的尾砂中综合回收萤石、石英的尝试,并进行了经济分析,效果显著。湖南铅锌矿甚多。然而,目前众多铅锌选矿厂一般只回收铅、锌、银等金属矿物,对矿石中的石英、萤石、玉髓、方解石、重晶石等矿物大都丢弃了。1985年,长沙环保研究所用我矿尾砂,进行了回收石英、制造玻璃的试验,从理论上和工艺上取得了明显效果,已于1987年通过部级鉴定。笔者现就铅锌矿的石英、萤石等综合利用、全面回收国家矿产资源作一浅析。 (一)矿石特性邵东矿属中低温热液裂隙充填矿床,其中一个矿带(F_1)现已探明的有11个铅锌矿体,含铅锌金属量8万吨、银57.9吨、镉122吨、萤石
This paper introduced the comprehensive recovery of fluorite and quartz from tailings of lead-zinc sorting in Shaodong lead-zinc mine and carried out economic analysis with remarkable results. There are many lead-zinc mines in Hunan. However, at present, many lead-zinc concentrates generally only collect metal minerals such as lead, zinc and silver and discard most of the minerals such as quartz, fluorite, chalcedony, calcite and barite in the ore. In 1985, Changsha Environmental Protection Research Institute used mine tailings to carry out the experiment of recovering quartz and making glass, and obtained the obvious effect in theory and technology. It passed the ministerial appraisal in 1987. The author is now on the lead-zinc mine quartz, fluorite and other comprehensive utilization of a comprehensive recovery of national mineral resources for a brief analysis. (I) Ore characteristics Shaodong ore deposit is a medium- and low-temperature hydrothermal fissure deposit. One ore zone (F_1) has now been identified with 11 lead-zinc ore bodies, including 80,000 tons of lead and zinc metals, 57.9 tons of silver, 122 tons, fluorite
