white quartz ore dressing process



Quartz

Quartz is a hard crystalline mineral composed of silica silicon dioxide .The atoms are linked in a continuous framework of SiO 4 silicon oxygen tetrahedra with each oxygen being shared between two tetrahedra giving an overall chemical formula of SiO 2.Quartz is the second most abundant mineral in Earth s continental crust behind feldspar
