西藏拉屋锌铜矿床伴生组分赋存状态及工艺性质
Occurrence and Technology of Associated Elements in Lawu Zinc-Copper Deposit
摘要
Abstract
It is found that the essential useful components are Cu,Zn,Pb,the associated useful components are W,Sn,Bi,Ag,at a percenttage of 0.050％,0.032％,0.030％ and 144.9 × 10-6,from Lawu zinccopper deposit by micro analysis,chemical analysis,scanning electron microscope and energy spectrum analysis,X-ray diffraction analysis.W is mainly formed by scheelite; Sn by cassiterite and stannite; Bi by native bismuth and Ag by silver-chalcopyrite.The yield of particles ＞0.25 mm is 49.24％ ; ＜0.075 mm is 23％ after broken in sieve analysis.The grade of W,Bi and Ag tends to be higher from the coarse particle size to fine ones and Sn has no change.The occupancy ratio almost is 1/3 with particles ＞0.25 mm and ＜0.075 mm respectively,the same as the essential components very benefit for the recovery.关键词
