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 column was opted …

The effect of pH on the flotation recovery of barite and calcite using SDS and NaOL as collectors was studied by micro-flotation tests, as shown in Fig. 3. It could be seen from Fig. 3 that the flotation recovery of barite with SDS increased in the pH range from 8.0 to 10.0, and at an optimum pH of approximately

Therefore, in the flotation process of barite ore, both inhibitors and collectors play a very important role. Under conventional flotation conditions, the recovery rate of barite can reach more than 80%, and the collector also has good ing properties, so the activator and ing agent are rarely involved in barite flotation.
