Talcum powder purification processing technology

1. Flotation is due to the natural floatability of talc. Therefore, hydrocarbon oil collectors can be flotated. The commonly used collector is kerosene, and flotation oil is used as the foaming agent. The foam generated by methyl isobutyl carbinol (MIBC) is relatively brittle, making it easy to obtain high-quality concentrate. The talc flotation process is relatively simple, requiring only one rough selection, one sweep, and 2-4 selections to obtain the final concentrate. 2. Manual selection is based on the different slipperiness of talcum powder and gangue minerals. Talc has good slipperiness. The higher the grade, the better the slipperiness. It is easy to identify by feel. Most domestic talc mines commonly use hand selection to produce high-grade talc blocks. 3. Electrostatic beneficiation of talc ore except talc. It also contains magnesite, magnetite, pyropyrite, tremolite and other minerals with an embedded particle size of about 0.5mm. In an electrostatic field, talc is negativ...
