Froth‐flotation reagents for coal: Distillation fractions ...

Three commercial oils commonly used for the froth flotation of fine coal were fractionally distilled in a high-efficiency laboratory column. When the individual fractions were tested for flotative power on Gresford and Bedlington fine coals, little variation was found, except that components boiling at temperatures below 180° or above 280° had less power than those in the middle range.

The interaction of frothers with hydrophobic and ...

2021-11-7  1. Introduction. Froth flotation has been widely used in coal and mineral processing plants to separate valuable materials from wastes, in which air bubbles attach to hydrophobic particles and carry them from the pulp phase to the froth phase before the froth transports the bubble-laden particles to flotation concentrates [].In this process, frothers (weak surfactants), are added to generate ...

Enhancement of Flotation Performance of Oxidized Coal

2021-11-16  Conventional hydrocarbon oil cannot adhere effectively to oxidized coal, resulting in a low yield of clean coal. In this study, a high-speed homogenizer was used to emulsify LDD (laurylamine dipropylene diamine) and kerosene, which enhanced the flotation efficiency of oxidized coal. The flotation results showed an increase from 4.12% (only kerosene) to 23.33% (emulsified oil).
