Abstract: This paper studies the technology status of schee lite metallurgy in China by analyzing the existing technology problems. Scheelite dressing and metallurgy need to be integrated to reduce the requirements of concentrate grade for improving the dressing recovery. Correspondingly, a new leaching system suitable to treat low grade scheelite concentrate should be developed. The comprehensive recovery can be raised by 10 %~15 %. Additionally, new leaching system should be helpful to the comprehensive utilization of associated el - ement, W-Mo separation, waste water and harmful salt reduction.
