Barite, a name which was derived from the Greek word “barus,” meaning heavy, is the mineralogical name for barium sulfate. In commerce, the mineral is sometimes referred to as “heavy spar” or “barytes.” “Spar” means almost any transparent or translucent, readily cleavable, crystalline mineral having a vitreous luster.
There ara two processes which are typically used to beneficiate barite ores. The first process, flotation, depends on a combination of physical and chemical characteristics to separate the barite from gangue components. The second process, gravity concentration, depends on the high specific gravity of the barite to separate it from the gangue components found in the ore.
The plant consists of three main sections : 1. a three - stage crushing station where the barite raw material is reduced from a top size of about 600 mm down to 20 mm;
2. a two-stage jigging section with interstage grinding whereby a gravity concentrate is produced;
3. a flotation line for the recovery of barite values still contained in the fine fractions discarded from the preceding section.
