近年来,在钨资源以白钨矿为主的国外,白钨矿浮选获得较广泛的应用。美国联合碳化物公司针对坦佩犹特白钨矿研制了一个新的“石灰浮选法”—加石灰搅拌矿浆,用碳酸钠和硅酸钠作调整剂,用油酸和环烷酸皂的混合物(1:1)作捕收剂进行白钨矿浮选。根据江西冶金学院做的选矿试验,广西资源县钨矿新建了一座100吨/日的白钨矿浮选厂,经过调试,于1983年8月投入生产。广西资源县钨矿属矽卡岩型矿床。主要金属矿物为白钨矿,其次为辉铋矿、铜蓝、黄铁矿、方铅矿等;脉石矿物主要为方解石、萤石、石英,其次为石榴石、透辉石、阳起石、长石、符山石及少量的电气石,绿泥石、斧石、磷灰石等。白钨矿呈星状分布于石英、透辉石、石榴石、绿泥石、方解石、长石等矿物中。一般粒度0.1～
In recent years, tungsten resources in scheelite-based abroad, scheelite flotation access to a wider range of applications. United Carbide has developed a new “lime flotation method” for the Timber-Uut teflon ore - adding lime to the slurry, using sodium carbonate and sodium silicate as adjusters, oleic acid and naphthenic acid soap The mixture (1: 1) as a collector for scheelite flotation. According to the beneficiation test done by Jiangxi Metallurgical Institute, a tungsten ore flotation plant of 100 tons / day was built in Tungsten Mine of Guangxi Ziyuan County. After commissioning, it was put into production in August 1983. Tungsten ore resources in Guangxi Province are skarn-type deposits. The main metallic minerals are scheelite, followed by bismuthinite, copper blue, pyrite and galena. The gangue minerals are mainly calcite, fluorite and quartz, followed by garnet, diopside and actinolite , Feldspar, Fu Shan and a small amount of tourmaline, chlorite, ax, apatite and so on. Scheelite is star-shaped distribution in quartz, diopside, garnet, chlorite, calcite, feldspar and other minerals. The general size of 0.1 ~
