Grinding of quartz is comparatively difcult because of high hardness (Mohs scale hardness is 7). In Sri Lanka vein quartz is mainly used in the ceramic industry as a major raw material.
Different types of surface mining in use are open casting/quarrying, mountaintop removal, placer mining, dredging, hydraulic and strip mining. Underground Mining This is the removal of valuable minerals from the earth by taking both people and equipment into depths from the earths surface.
Lanka, which have been exploited economically since 1958 (Meyer, 1983; Lanka Mineral Sand Ltd., 1999). In Sri Lanka, separation of beach sands into its constituent minerals at the Pulmoddai mineral separation plant is accomplished through a combination of gravity, magnetic and electrostatic methods.

Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal, drag or buoyant forces). The resistance to motion, known as drag force, by a medium such as heavy media, water or even air, is one such force.
