Study of Flotation Effect of ST-1 Complex Reagent

Abstract:

There are lots of problems in coal flotation reagents. For example, it is difficult to disperse in coal pulp, it needs a large consumption, and its selectivity is poor. So this paper refers that kerosene can be made into compound kerosene by using different chemical products and surfactants, and then used for coal flotation. Tests proved that when the ST-1 Complex Reagent dosage is 500g/t, kerosene dosage is 900g/t, clean coal ash consistent is the same, and clean coal yield is closed, collector dosage saved 44.44%, and the fastest floating speed of clean coal is 99.3g/min, 4.8g/min fast than kerosene, Zeta potential is-28.9409mv after kerosene effect, Zeta potential is -13.2555mv after ST-1 Complex Reagent effect.
