Three processes to deal with zero loss of low-grade tungsten concentrate

Through the three processes (material preparation, material sintering - leaching, leachate purification) after treatment of low-grade tungsten concentrate, the tungsten is sold in the form of sodium tungstate or white tungsten , ammonium paratungstate, tungstic acid or tungsten trioxide, and from Comprehensive recovery of other useful components in the leaching residue. The value of tungsten ore is lost.

Low-grade tungsten concentrate chemical beneficiation treatment process

Some low-grade tungsten concentrates produced by tungsten preparation plants do not meet the quality standards. The grade of WO3 is 5-30%, and other impurities are also relatively high. Mainly for low-grade ore of tungsten fine mud, tungsten, tin ore, tungsten-iron sand and other refractory containing tungsten intermediate products. Such products are chemically beneficiated to produce tungsten in the form of sodium tungstate or white tungsten, ammonium paratungstate, tungstic acid or tungsten trioxide, and other useful components are recovered from the leach residue.

The principle of chemical beneficiation of low-grade tungsten mineral raw materials is shown in Figure 7-8. The treatment process can be divided into:

1. Material preparation and sintering of materials - leaching

Second, the purification of leachate

Third, the preparation of tungsten chemical concentrate
