Problems solved by technology

At present, there are few biotite purification processes in China, and the only methods (such as "A Method for Purification of Mica", Application No.: 201210134174.8) only use stirring and ultrasonic treatment, the purification efficiency is not high, and the purity also to be verified

Embodiment Construction

[0017] Specific embodiments of the present invention are given below to further describe the composition of the present invention in detail.

[0018] A biotite purification process, comprising the following steps:

[0019] (1) Crushing: Send the biotite to the jaw crusher for primary crushing, and then the primary crushed ore is screened by a vibrating screen, and then sent to the single-cylinder hydraulic cone crusher by a belt conveyor for secondary crushing; secondary crushing The final ore material is sent to the multi-cylinder hydraulic cone crusher for fine crushing, and finally the finely crushed raw ore is screened by a vibrating screen into 4mm ore particles;

[0020] (2) Grinding: Use a ball mill to grind, send the ore particles evenly to the ball mill, and use the spiral classifier to screen the powder, and send the unqualified ore powder to the ball mill to continue grinding to obtain the ore powder;

[0021] (3) Pulping: use a slow mixer to pulp, 5-stage multi-st...

Abstract

The invention relates to a biotite purification process and belongs to the technical field of purification methods. The biotite purification process includes the steps of firstly, crushing, to be more specific, preliminarily crushing biotite in a jaw crusher, screening the preliminarily crushed ore with a vibration screen, and using a belt conveyor to convey the screened ore to a single-cylinder hydraulic cone crusher to perform secondary crushing; feeding the ore after the secondary crushing into a multi-cylinder hydraulic cone crusher to perform fine crushing, and screening the raw ore after the fine crushing with a vibration screen to obtain ore particles of 0-10mm. The biotite purification process has the advantages that the biotite purification process is simple, high in operability, capable of greatly lowering construction complexity by the simple flow, low in energy consumption, high in yield, convenient in large-scale production and capable of increasing yield and lowering energy cost; the purified biotite is widely applicable to various fields, good in quality and capable of greatly increasing economic benefits.

Description

technical field [0001] The invention relates to a biotite purification process, which belongs to the technical field of purification methods. Background technique [0002] Biotite is one of the mica minerals and is a silicate mineral. Biotite is mainly produced in metamorphic rocks, but also in some other rocks such as granite. Biotite can range in color from black to brown, red or green, with a vitreous luster. The shape is plate-like and columnar. In recent years, biotite has also been widely used in decorative coatings such as real stone paint. The crystal form of biotite is similar to that of phlogopite. The color is black, dark brown, sometimes with reddish, greenish or other hues. Those with high titanium content are light reddish brown, while those rich in high-valent iron are green. Transparent to opaque. Glass luster, black has a semi-metallic luster. Hardness 2-3, specific gravity 3.02-3.12. Biotite can be altered into other minerals such as chlorite, musc...
