The Democratic Republic of Congo (DRC) holds antimony ore reserves of approximately 200,000 tonnes, with an average grade of 8.5%. Some ore deposits exhibit stibnite content ranging from 60% to 66%. Through mineral processing, a concentrate with over 65% antimony content and a recovery rate exceeding 85% can be obtained, making it suitable for both metal extraction and chemical production.
