| titleOfInvention | Beneficiation method for micro-fine particle tungsten ore |
| abstract | The invention provides a beneficiation method of micro-fine tungsten ore, belonging to the technical field of beneficiation. Firstly, grinding tungsten ore, then adding a mixture of regulator sodium carbonate, inhibitor sodium alginate and collector 731 oxidized paraffin soap and polyether to stir and size, and roughly selecting tungsten by using a flotation machine to obtain roughly selected concentrate and roughly selected tailings; adding sodium alginate into the roughed concentrate, carrying out five-time concentration to obtain concentrate 1, adding a mixture of 731 oxidized paraffin soap and polyether into the roughed tailings, carrying out scavenging twice, obtaining scavenged tailings, adding a regulator acidified water glass and a collector poly (N-isopropylacrylamide) into the scavenged tailings, carrying out flotation by using a flotation column, obtaining concentrate 2 and final tailings, and combining the concentrate 1 and the concentrate 2 into final concentrate. The method solves the technical problem that the micro-fine tungsten ore is difficult to effectively recover, and has important significance for realizing the high-efficiency utilization of the low-grade tungsten ore which is difficult to treat. |
