Wollastonite enclosing rock is divided into two types: marble type and skarn type.

The skarn type is mainly lenticular, cystic, irregularly banded, etc., in which iron impurities in wollastonite are generally higher, and the main veins are garnet, diopside, calcite and quartz, and garnet and diopside are sorted out by strong magnetism and calcite and quartz are sorted out by flotation.

The marble type is more complex, mainly agglomerated and saccular, and its wollastonite is distributed in the form of flower and worm strips, with low iron content, and the veins are mainly calcite and quartzite and a small amount of tremolite, which are mainly sorted out by flotation, and calcite and quartzite are sorted out.

Wollastonite conventional beneficiation and purification methods

Wollastonite conventional sorting methods are: artificial hand-selection, flotation, single magnetic separation, magnetic separation - flotation (electrowinning), beneficiation purpose is mainly to reduce the iron content, separation of calcite and waste rock.

• Hand-selected, mainly through the artificial selection of rich ore or through the conveyor belt artificial hand-selected rich wollastonite, mainly for wollastonite content of higher ores.
• Flotation, mainly according to the differences in physical and chemical properties of wollastonite and calcite surface, through flotation can effectively separate them, and at the same time can remove a large number of iron impurities, improve the grade of wollastonite.
• Single magnetic separation, mainly utilizing the weak magnetic minerals such as garnet and tremolite in the original ore, wollastonite is not magnetic, through dry or wet strong magnetic separation technology to separate wollastonite and other veins, can also remove a large number of iron-containing ores to enhance the overall grade.
• Magnetic separation - flotation, mainly applicable to the treatment of low-grade wollastonite, first through the magnetic separation of weak magnetic ore, and then through the flotation of wollastonite and quartzite, calcite separation.

Wollastonite beneficiation latest efficient sorting method - artificial intelligence optical sorting

Artificial intelligence optical sorting is a physical sorting technology, through the wollastonite and calcite, quartz, limestone and other associated minerals and other surface characteristics of the differences in sorting, the criteria are mainly color, texture, shape and other types of surface characteristics of the differences, through artificial intelligence means, the establishment of the data model, to achieve the purpose of accurately sorting out the wollastonite and the associated stone.

The traditional ore optical sorter can only sort by the single criterion of color, if the color of the associated quartz or other impurities close to wollastonite, the color sorter can not accurately sort out wollastonite. Only the artificial intelligence ore sorting machine integrates the multi-dimensional characteristics of good and bad materials in the raw ore, establishes a sorting model, and achieves the final sorting goal through artificial intelligence technology, with precision, high speed, and low take-out.

Project Advantages

• When wollastonite has a high dissociation degree, the artificial intelligence machine can rapidly and effectively sort it from tailings. This approach provides numerous advantages, including high efficiency, speed, ease of use, and affordability, with costs limited to the one-time equipment purchase and subsequent power supply.
• In the case of a general dissociation degree, the artificial intelligence machine can effectively separate valuable wollastonite ore from useless waste rock. This will directly minimize the volume of ore subjected to magnetic separation or flotation, leading to savings in magnetic separation and flotation costs, and a reduction in tailings processing.

Mingde optical artificial intelligence sorting machine has gained significant traction in the field of ore sorting, proving its effectiveness across various ore types. We specialize in accurately and efficiently sorting ores based on their dissociation degree and visible surface differences. Having developed and perfected the technology, our equipment has successfully demonstrated its value within different industrial and mining enterprises.
