METHOD FOR SEPARATING VALUABLE MINERAL FROM CLASTIC RESOURCES SUCH AS SEA SAND OR RIVER SAND

摘要

PURPOSE: A collecting method of useful minerals from clastic resources including sea sand and river sand is provided to improve the purity of the collected minerals. CONSTITUTION: A collecting method of useful minerals from clastic resources including sea sand and river sand comprises the following steps: separating the clastic resources into heavy minerals and light minerals using the relative weight difference of the minerals(M20); consecutively transferring the heavy minerals through a passage with plural magnets having the different magnetic force for separating the heavy minerals into plural mineral groups(M30); and assorting target minerals from the plural mineral groups using the difference of the electrical property of each mineral(M40).
