A process and method for separation, extraction and filtration of heterogenic mineral compositions from the offshore coastal region is described. the coastal region, abutting a distance of 1 or 2 kilometer from the surface water of the sea is taken into consideration and the coastal sands occurring in this region which are rich in heavy mineral are first dredged by using suitable dredging equipment. Further the dredged sand is cleaned for getting rid of impurities and later the heavy mineral contents contained in the sand are separated by using spirals which are primary concentrators. consequentially the heavy minerals are separated from the constituent sand by various process of separation sieves, magnetic means and electrostatic methods. this method and process assumes critical significance given that at present the sand dredged from the sea coast by various agencies are put to less use after extraction of few principle minerals in conventional methods.
