Both floatation separation and gravity separation can work to get high grade baryte.2. Gravity Separation: This method works based on the density difference between barite and associated mineralsHere the choosing of barite jig machine is the key to …
3.2 Gravity separation at coarse size The specific gravity of barite is 4.5 as a-ainst 2.65 for quartz, the major gangue associated with the sample. So there exists possibility of concentrating the low grade barite sample by gravity separation technique. The results of liberation studies shows that a fair liberation of barite from the associated
Jan 08, 2018 The sample was then concentrated using the gravity separation and leaching processes. The microstructural and chemical composition analyses of the products of concentration were carried out to establish the effectiveness and efficiency of the methods for the recovery of Azara barite mineral ore.

Barite was used in Barvoys medium baths, read up on that and you'll see the recovery method used, which was flotation. Farly old process.
Therefore, DMS methods are widely used in the separation of coal and various metal ores and non-metallic ores. Direct separate clean coal and waste rock; separate coarse waste tailings and rough concentrate. For the ordinary gravity separation method, the lower limit of the feeding ore is about 2-3mm (the coal is 3-6mm).
