Abstract
The invention discloses a mineral separation process for impurity removal and purification of nonmetallic minerals, which utilizes the difference of optical properties among different minerals and adopts a photoelectric color selector to remove and improve the quality through a grading selection process. The special crushing and grinding machine for the non-metallic ore is provided with a closed ore grinding-screening self-circulation system, so that qualified products are discharged in time, over-crushing is prevented, and the yield is improved.
Description
Technical field
It is specifically a kind of to utilize disintegrator, photoelectric colour sorter and magnetic separator phase the present invention relates to mineral separation process for non-metal ore
In conjunction with ore-dressing technique, the present invention is suitable for the nonmetallic ores removal of impurities purification such as wollastonite, calcite, quartz.
Background technique
With the rapid development of industry, requirements at the higher level are proposed to parameters such as the particle shape of nonmetal mineral product, granularity and whiteness,
Nonmetallic ore purification is to remove the objectionable impurities mineral for influencing product whiteness and physicochemical property, and conventional ore-dressing technique has gravity treatment, magnetic
Choosing, flotation etc., the effect is unsatisfactory for the magnetic separation of weak magnetic minerals thin for disseminated grain size, flotation higher cost and pollution environment.
Currently, China's nonmetallic ore fine crushing device falls behind relatively, there is the disadvantages of crushing is serious, size distribution is unreasonable, energy consumption is high.
Photoelectric colour sorter is made of the part such as charging gear, photoelectric detection system, signal processing apparatus, separator, is had
Have the advantages that high reliablity, sharpness of separation are high, treating capacity is big.
The dedicated disintegrator of nonmetallic ore developed by Zhengzhou Institute of Multipurpose Utilization of Mineral Resources, CAGS has envelope
The ore grinding closed-screening self-circulation system, qualified products are discharged in time, prevent crushing, its advantage is that high yield rate, grade point
Cloth is narrow, particle shape is excellent, low energy consumption.
