If the quartz penetrates too deeply into the ore, or the iron, zinc, or lead content is abnormally high, then froth flotation is used. The product is a 98% pure baryte (by mass); the purity should be no less than 95%, with a minimal content of iron and silicon dioxide. [5] : 7 It is then reduced by carbon to barium sulfide: [5] : 6

Centrifugation, flocculation, filtration, gravity sedimentation, flotation, and electrophoresis techniques are the conventional dewatering methods widely used (Pragya et al., 2013). Similarly, solar, convective, spray-, and freeze-drying are the conventional methods used to dry algal cultures (Del Campo et al., 2007).
