摘要
分别用731氧化石蜡皂和ZL作白钨矿的捕收剂,选别含钙脉石矿物高的白钨矿和多金属白钨矿,小型试验和工业试验结果表明,用ZL获得的钨精矿品位和回收率均高于用731氧化石蜡皂,且ZL捕收剂用量少.当含钙脉石矿物高的白钨矿矿石的原矿品位为WO30.58%时,用ZL作捕收剂可获得钨精矿品位66.82%、回收率90.98%的工业试验指标.ZL对白钨矿的捕收能力强、选择性好,且用量少.
The 731 oxidized paraffinum sodium salt and ZL were separately used as collector to pick out scheelite from high calciferous gangue and polymetallic scheelite, the laboratory experiment and industrial experiment were carried on. It has been proved that using ZL, the grade and recovery of the concentrate is higher than using 731 oxidized paraffinum sodium salt with less reagent consumption. Using ZL as collector, a tungsten concentrate having grade of 66.82% and recovery of 90. 98% were obtained in industrial experiment from the scheelite ore with high gangue mineral of WO3 content about 0. 58%. ZL is one of the most effective collectors for scheelite.
