| 摘 要： | 根据原矿中白钨矿呈细粒嵌布的特点，采用全浮工艺流程，以碳酸钠为调整剂，水玻璃为脉石矿物的抑制剂，ZL为捕收剂浮选回收白钨矿。对含WO31.43%的原矿获得了含WO3为32.34%的白钨中间精矿，钨粗选回收率95.32%；通过常温精选与加温精选比较试验，对钨中间精矿确定采用加温精选，获得了含WO3为66.16%，回收率91.78%的精矿。

| Abstract: | According to the characteristics of fine-grained disseminated scheelite in run-of-mine, the scheelite was concentrated by adopting the full flotation process with sodium carbonate as regulator agent, sodium silicate as inhibitor for the gangue minerals, and ZL Pharmacy as collector. 32.34% of the coarse scheelite concentrate (WO3) with tungsten recovery of 95.32% was obtained from the raw ores with grade of 1.43%. Through the comparison tests between concentration at normal temperature and heating temperature, it was determined to concentrate the rough tungsten by heating, by which the high-quality scheelite with tungsten (WO3) of 66.16% and tungsten concentrate recovery of 91.78% was obtained. |
