Study status and prospects in flotation reagents and techniques of tungsten ores

The article describes the current status and progress of collectors,regulators and processing techniques for the flotation of scheelite and wolframite,and prospects the development direction of the flotation of scheelite and wolframite.It also points out that the high efficiency collector and depressor for the flotation of scheelite and wolframite should be developed,as well as flotation and smelting process should be combined.The regant combination laws,cooperative effects of combined reagents and action mechanism of reagents and minerals are need to deeply study.In addition,the flotator used for efficiently recoverying super-fine tungsten particles should be developed,so as to shorten the long process of scheelite and wolframite flotation.
