The Beneficiation of Barite by Agglomeration

The beneficiation of barite in mill tailings using an agglomeration technique has been demonstrated. Barite was selectively absorbed from a conditioned aqueous slurry into a collector oil by mechanically mixing slurry and oil. The resulting oil-bonded barite-containing agglomerate was washed, to remove gangue material, and further mechanically contacted with dilute H2S0 4 This treatment resulted in the transfer of barite into the aqueous phase. Grades as high as '97% BaSO,, with recoveries of 80%, have been obtained using this technique.
