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).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) Dehydrating and drying process; (CC) Finish; (M10) Screening process; (M21) First assorting process using the relative weight difference; (M22) Second assorting process using the relative weight difference; (M30) Assorting process using magnetic force; (M40) Assorting process using the difference of the electrical property
