· Barite-fluorite separation. Fatty acids can actively interact with Ca and Ba sites on the surfaces of fluorite and barite, causing nonselective adsorption [38,115,169]. Therefore, fluorite and barite exhibit similar floatabilities, and their separation by flotation is difficult [169,170]. Multiple flotation stages are usually required.

· The barite ore mined in the early stage are mostly high-grade ores, usually using low cost and low-tech hand sorting method or gravity separation process. However, with the low-grade and the complexity of barite ore, magnetic separation, flotation and combined separation methods have been widely used in the separation of barite ore.
· Barite (barium sulphate) often occurs as large veins or beds, as gangue mineral in various mineral veins, in limestones, sandstones and like deposits.The ores are generally low grade and require concentration by flotation to meet market specifications. Barite, which has the ability to influence other materials with its basic characteristics, makes this heavy spar indispensable in maintaining ...
Dry processing of iron ore presents an opportunity to eliminate costs and wet tailings generation associated with flotation and wet magnetic separation circuits. STET has evaluated several iron ore tailings and run of mine ore samples at bench scale (pre-feasibility scale). Significant movement of iron and silicates was observed, with examples ...

· The above results suggest that flotation separation of barite from calcite can be realized when the AWG is used as a depressant for calcite. Hence, flotation tests of barite and calcite mixture with the mass ratio of 4:1 were performed in the present and absence of AWG using NaOl as the collector at pH ˜8, the result of which is shown in Table 2.
