Gravity concentration of fine particles complex ores-containing baryte using laboratory-built mineral jig

This study uses environment-friendly and indigenous processes to liberate, separate and recover barite from gangue minerals. Barite ores were randomly selected, comminuted, screened, characterized, and beneficiated using a laboratory-built mineral jig. The effect of mineral liberation on separation efficiency, recovery, and yield was examined. The specific gravity of the barite ores was increased from 3.97±0.0105 to 4.17±0.20 and from 4.00±0.0458 to 4.20±0.2 without the use of chemicals. Likewise, higher barite recovery and yield were observed. However, the separation efficiency of the jigging process was low due to middling (a complex particle consisting of barite and gangue minerals).
