Domain.
Background technique
About 20 kinds of mineral comprising tungsten on the explored earth, but have economic development value is scheelite and black tungsten
Mine.Since the weight of tungsten ore is relatively high, than weighing about between 6-8, thus weight can be passed through when only by coarse grained release
High grade and recycling are realized in power separation.But tungsten ore is usually in granite form, quartz mine and carbonate deposition rock shape
Formula containing at the contact point between tungsten ore generate.But can find that scheelite is produced as fine grained in actually mining, it is adopting
When with gravity separation, due to generating many fine graineds because of high brittleness in crushing or process of lapping, thus the rate of recovery reduce compared with
It is more.Therefore, it is necessary to the floatation separating technology for effectively carrying out fine grained processing be developed, so that tungsten ore is enriched with.
In the FLOTATION SEPARATION of tungsten ore, do not use inhibitor when can not almost separate mineral because tungsten ore, apatite,
