talc processing extraction
WebNov 23, 2011 Quantitative extraction of the iron present in talc 78 happens at temperatures over 900 C, where clinochlore decomposition has occurred. Fig. 3 also highlights that the highest level of iron extraction happens during the first 15 minutes of reaction, and that this does not depend on temperature.

Potash and Solution Mining | YanCoal
Solution mining involves dissolution of the potash with water. Wells are drilled into the potash-bearing area (sylvinite bed) and water, later brine, is pumped down the wells to dissolve the potassium chloride (KCl) (potash product) and sodium chloride (NaCl) (waste salt) that is in the sylvinite bed. Brine is returned to the surface and is ...
Talcs | SpringerLink
Abstract. Talc is a naturally occurring magnesium silicate mineral, widely used as a polymer filler. Its main differentiating features in this context are its softness (it is the softest mineral known) and lamellarity (platiness). Useful deposits are widespread and processed by conventional mining operations to produce filler grade material.
