Talcum Powder Processing Plant
Extraction, beneficiation, and processing of talcum powder produces talcum. "Extraction" is defined as removing ore material from a deposit and encompasses all activities prior to beneficiation. "Beneficiation" of talcum includes concentration, generally by physical removal of unwanted gangue; also considered beneficiation is the regulation of product size, or other steps such as agglomeration to improve its chemical or physical characteristics prior to processing. "Processing" of the concentrated product into talcum typically involves the use of pyrometallurgical techniques.
Talcum powder Processing Flow
- Mining; Mining talcum powder begins at ground level be identified by diamond drilling core samples on a grid hundreds of feet into the earth.
- Crushing; The crushed material is transferred by belt to an ore storage building, which holds up to 220,000 tons of talcum powder.
- Concentrating; A series of conveyor belts continuously feed the ore into ten large 27-foot-diameter
- Mixing; talcum powder is added to meet the requirements of steel customers in the blast furnace process
- Pelletizing; Pellets are screened to meet the size specification, with undersized or oversized pellets crushed and returned to the balling drums
The choice of talcum powder processing plant depends on the type and amount of feed material to be crushed. Jaw crushers as primary crushers used at mining operations today, although some operations use impact crushers, low-speed roll sizers and feeder breakers. Cone crushers remain the most popular for fine crushing applications, although some mines use vertical impact crushers for tertiary and quaternary crushing.
