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.
