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.

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 ...

2016-3-24 During the past decade, column flotation cells have become widely accepted for the upgrading of fine coal streams. this popularity can be largely attributed to the ability of columns to remove high-ash clays from the froth product via the addition of wash water to a relatively deep froth. while there are numerous successful column installations,

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).

2018-5-30 Reverse flotation was proposed as a potential method for the upgradation of low rank thermal coal. Higher combustible matter recovery in the float could be obtained using reverse flotation method compared to conventional flotation method. In order to reduce the entrainment of fine particles, oleic acid (OA) was used as froth regulator in coal reverse flotation process. Experimental data
