Problems solved by technology

[0002] In the flotation separation process of pyrophyllite, quartz and carbonate gangue minerals, since pyrophyllite and quartz are silicon-containing minerals, their buoyancy is close to that of separation; Impurity minerals such as salt are easy to muddy and affect the surface flotation performance of pyrophyllite, which makes it difficult to separate pyrophyllite from gangue minerals such as quartz and carbonate; The development and utilization of pyrophyllite are limited by factors such as the variety and dosage of agents, and the high production cost.

Abstract

The invention discloses a floatation separation method for pyrophyllite and quartz. The method comprises the following steps: in a floatation process, regulating the pH value of ore pulp to 4-5 by using sulfuric acid; adding water glass and sodium hexametaphosphate for serving as quartz and gangue mineral inhibitors; adding mixed amine and oxyparaffin soap for floating pyrophyllite to obtain agalmatolite concentrate. By adopting the method, floatation separation of pyrophyllite and quartz from carbonate gangue mineral can be effectively realized. The agalmatolite concentrate of which the pyrophyllite content is 84.33-86.25 percent and the recovery rate is 78.91-85.24 percent is obtained by performing once rough concentration, three times of scavenging and four times of concentration under the condition that the pyrophyllite content is 50.11-58.67 percent.

Description

technical field [0001] The invention relates to a mineral flotation separation method, in particular to a flotation separation method of pyrophyllite and quartz. Background technique [0002] In the flotation separation process of pyrophyllite, quartz and carbonate gangue minerals, since pyrophyllite and quartz are silicon-containing minerals, their buoyancy is close to that of separation; Impurity minerals such as salt are easy to muddy and affect the surface flotation performance of pyrophyllite, which makes it difficult to separate pyrophyllite from gangue minerals such as quartz and carbonate; The development and utilization of pyrophyllite are limited by factors such as many types and dosages of agents, and high production costs. Contents of the invention [0003] In order to overcome the above-mentioned shortcoming of prior art, the object of the present invention is to provide a kind of flotation separation method of pyrophyllite and quartz, can reclaim pyrophyllit...
