Abstract

The invention discloses a method for removing micas in nephelite by using a cyclone, which comprises the following steps of: (1) preprocessing a nephelite raw ore into an ore pulp consisting of nephelite powder, mica powder and water; (2) pumping the ore pulp into the cyclone by using a slurry pump; and (3) under the action of the centrifugal force of vortex, throwing spherical nephelite particles to a side wall of the cyclone to ensure that the spherical nephelite particles lose energy and are settled down, and then serve as underflows to flow out from the bottom of the cyclone, wherein the fluid resistance endured by sheet mica particles is greater than that of the spherical nephelite particles to ensure that the sheet mica particles cannot be thrown to the side wall of the cyclone to lose energy and be settled down; the fluid resistance endured by the sheet mica particles during settling down is greater than that of the spherical nephelite particles to ensure that the settling speed is slow; and the sheet mica particles are suspended in solid-phase two-phase flow to serve as an overflow which flows out from the top part of the cyclone under the pressure of a slurry pump. A product processed by the process method has a higher yield compared with the nephelite raw ore, and the mica content in the product is low.

Description

technical field [0001] The invention relates to the technical field of ore removal of impurities, in particular to a method for removing mica in nepheline by using a cyclone. Background technique [0002] Nepheline is a good ceramic raw material, which often contains mica, and some of them lose their value because of the high content of mica. At present, there is no method to remove mica from nepheline ore. Contents of the invention [0003] In order to overcome the deficiencies in the prior art above, the present invention provides a method for utilizing a cyclone to remove mica in nepheline. After the process is processed, the product has a high recovery rate relative to the ore of nepheline, and the mica in the product Low content. [0004] The purpose of the present invention is achieved through the following technical solutions: the method utilizing cyclone to remove the mica in nepheline is characterized in that: comprises the following steps: [0005] (1), carry o...
