[0025] The first example of the flotation separation method of wollastonite mineral and quartz of the present invention comprises the following steps:

[0026] 1. Mineral raw materials:

[0027] The content of wollastonite in the mineral raw materials used is 47.85%, quartz 21.73%, calcium carbonate 8.96%, and magnesium oxide 9.27%. The phase analysis shows that silicon mainly exists in the form of wollastonite and quartz, and the gangue minerals mainly exist in the form of carbon It exists in the form of acid salt, and a small amount of aluminum-containing minerals.

[0028] 2. Flotation agents and operating conditions:

[0029] Sodium hexametaphosphate 200g / t

[0030] Sulfuric acid 2000g / t

Abstract

The invention discloses a flotation separation method for aedelforsite and quartz. According to the method, sodium hexametaphosphate is taken as a mineral dispersing agent, sulfuric acid is taken as a pH value adjusting agent, acid soluble glass and tannin extract are taken as quartz inhibitors, and oleic acid and lauryl sodium sulfate are taken as aedelforsite mineral collecting agents. According to the flotation separation method, flotation separation of aedelforsite minerals from quartz minerals can be realized, the flow structure is simple, the medicament dosage is less, and the aedelforsite minerals can be recovered effectively. After flotation separation is performed under the condition that the content of feeding aedelforsite is 47.85-53.90 percent, aedelforsite concentrate of which the aedelforsite content is 93.83-95.18 percent and the recovery rate is 85.74-89.62 percent is obtained.

Description

1. Technical field [0001] The invention relates to a mineral flotation separation method, in particular to a flotation separation method of wollastonite and quartz. 2. Background technology [0002] In the flotation separation process of wollastonite mineral and quartz, the floatability of wollastonite mineral and quartz is close, which makes its flotation separation difficult; Particles form a large amount of slime, which interferes with the recovery of wollastonite, which not only complicates the structure of the flotation process, but also requires more chemicals, high production costs, difficulty in beneficiation automation, low recovery rate of wollastonite minerals, and limits the silica The development and utilization of limestone. 3. Contents of the invention [0003] The object of the present invention is to provide a method for flotation separation of wollastonite minerals and quartz, which can recover wollastonite minerals and obtain higher grade and recovery r...
