Abstract: In order to improve the comprehensive utilization level of tungsten resources, a new collector KF-1 was used to recover the skarn scheelite ore in Kafang mining area, Gejiu City, Yunnan Province. The results show that after the desulfurization flotation, the roughing tests at room temperature have been conducted, and the dosage of sodium carbonate, sodium silicate and collector has been determined as 2 000 g/t, 4 000 g/t and 150 g/t, respectively. Then after heating the coarse concentrate to 85 ℃ and holding for 1 h, the cleaning tests have been conducted, and the dosage of sodium hydroxide, sodium silicate and collector has been determined as 200 g/t, 1 200 g/t and 3 g/t, respectively. Finally, a tungsten concentrate assaying 55% WO₃ with tungsten recovery of 77% has been obtained. Compared with GY-10, the total recovery of tungsten has been increased by 14%, and the efficient comprehensive utilization of skarn scheelite in Kafang mining area has been realized.
