Barete is brittle and fragile, and the crystals are large tubular. The general beneficiation methods for barite selection are gravity separation, magnetic separation, and flotation.
The feldspar beneficiation process is suitable for potassium feldspar, sodium feldspar and nepheline syenite, etc.
Fluorite flotation process can be applied to fluorite ores with complex ore properties such as high mud content in the original ore, symbiosis of impurity minerals and fluorite, and fine particle size of useful minerals.
The graphite ore dressing process is mainly applicable to various graphite ores with different crystal forms and graphite ores with silicate minerals such as mica or pyrite.
