Processing method and process of crushed mica
a. Flotation is sorted according to the difference in surface physicochemical properties of mica and gangue. The ore is broken and ground to dissociate the mica monomer. Under the action of the agent, the mica becomes a foam product and is separated from the gangue. Mica flotation can be carried out in an acidic or alkaline slurry, and the long carbon chain amide cations and fatty acid anions are mica collectors . In the mica flotation process, three rough selections and three selections are required to obtain the mica concentrate. Therefore, mica ore float is used to recover mica and fine-grain mica below 14 mesh in pegmatite and mica schist. In China, mica ore flotation has not yet been produced and applied.
B. Wind-selected mica wind selection is realized by special equipment. The process is generally: crushing→sieving classification→wind selection. After the ore is crushed, the mica is basically formed into a flaky shape, and the gangue mineral feldspar , quartz and the like are in the form of massive particles. Accordingly, the multi-level grading is used to pre-divide the selected materials into narrower granules, and according to the difference in the levitation speed in the airflow, special air-conditioning equipment is used for sorting. The wind selection method is applicable to areas where water is scarce and has been used for actual production.
