A rougher concentrate was floated and cleaned three times to yield the results shown in table 11. The third cleaner concentrate had a BaSO4 content of 96.6 percent and a specific gravity of 4.47; 86.1 percent of the barite in the flotation feed was recovered. Of the barite in the ore, 83.2 percent was recovered. Illinois Waste Pond SampleWeb

Barite, also called baryte, is a non-metallic mineral product with barium sulfate (BaSO 4) as the main component. The name of barite comes from the Greek word barys, which means heaviness and implies the weight of this mineral. Because the specific gravity of barite is as high as 4.5, which is very rare in non-metallic minerals.Web
