湖南某白钨矿浮选试验研究

摘要

In the ore dressing tests of a scheelite deposit from Hunan Province, technical parameters for pulp conditioning and hydrophobic aggregation were optimized, through which the apparent diameter of scheelite was regulated, and a scheelite bulk concentrate with WO3 grade and recovery of 10. 44% and 86. 72%, respectively, was collected. Compared with the conventional flotation, the scheelite roughing recovery can be up 2. 09 percentage point, while the recovery for fine⁃grained (-10 μm) scheelite can be raised from 64.74% to 75.88%.%对湖南某白钨矿开展了选矿试验研究，通过强化调浆⁃疏水聚团工艺，调整白钨矿表观粒径，可获得品位10．44％、回收率86．72％的白钨粗精矿。相比常规浮选，白钨粗选段选矿回收率提高了2．09个百分点；微细粒级（－10μm）白钨矿回收率由64．74％提高至75．88％。
