![[Know Tungsten] Tungsten Concentrate Rougher Flotation – Heavy Medium Pre-selection Method Hydrocyclones image](http://0535idc.cn/en/wp-content/uploads/2017/10/img-201707212-351x185.jpg)
Tungsten concentrate rougher flotation is the first pre-selection process after it is explored form mine. Due to uneven distribution of tungsten concentrate in quartz vein mineral, waste ore will be blended during exploration process. Pre-selection of concentrate and waste ore will improve efficiency, save cost and time, lowering wastage.
