There are many alternatives within open pits and quarries but the great principles are identical. Most industrial materials and shallow metallic deposits (< 300 m) are mined by this method, which is the cheapest in practice. Talc is generally mined by open pit mining technique.
Talc Quarry Mining Equipment
Talc generally are mined by open pit mining methods. The material then is crushed. Gyratory crushers, jaw crushers, roll crushers, and impact mills are used for primary and secondary crushing. After crushing, the size of the material is further reduced to 50 micrometers or smaller by grinding, using ball mill, media mills, autogenous mills, hammer mills, or jet mills. The ground material then is classified by wet screening, dry screening, or air classification. At some plants, after initial crushing and screening, a portion of the materials can be delivered for construction sand application.
Talc Quarry Crushing Plant
The choice of talc quarry crushing machine depends on the properties and amount of material to be crushed. Gyratory and jaw crushers are the bulk of primary crushers applied in mining operations modern time. Impact crushers, hammer crusher, VSI crusher are often used in secondary crushing operations. Cone crushers remain the most popular for fine crushing applications, although some mines use vertical impact crushers for tertiary and quaternary crushing.
