METHOD FOR SEPARATION AND ENRICHMENT OF URANIUM BY USING ROASTING

摘要

PURPOSE: A separation concentration method of uranium is provided to separate and concentrate high concentrated uranium from low grade uranium mineral. CONSTITUTION: A separation concentration method of uranium comprises the following steps: a crushing stage (S10) which smashes uranium raw ore; a thermal processing step (S20) which heat-treats the crushed material; a pulverizing step (S30) which forms the crushed material in powder by pulverization; a particle isolation step (S40) which separates the pulverized powder; a magnetic sorting step (S50) which sorts the material using magnetic force; and a specific gravity separation step(S60) which sorts the non-magnetic product according to specific gravity difference(S60).
