Barite deposit at Mangampet is one of the world's largest deposits containing around 61 million tonnes of recoverable barite. Beneficiation of low grade barite dumps interlocked with schist and slate gangue was studied using amine as collector (reverse flotation) to avoid the collector coating on barite. Instead of conventional flotation cells, flotation …

Sodium oleate and pine oil are typically used as collector and frother in barite flotation at pH 10 [5,6]. However, oleate is sensitive to slimes [7], low temperatures [8,9], and hard-water ions [10]. In this regard, many other collectors have been explored in barite flotation. Barite is either prefloated

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
