Reverse Flotation IntechOpen
2018-9-12 Rank, mineral content and macerals are influencing the flotation performance and type because these are essential parameters for floatability of coal. Reverse flotation can be optimized for low rank coal because low rank coal can be suppressed more easily since hydrophobicity of low rank coals are more less due to its polar structures.

An overview of reverse flotation process for coal ...
Flotation is one of the most effective technologies for the up-gradation of coal fines of particle size below 0.5 mm because of the inherent hydrophobic nature of coal. Contrary to this, reverse flotation of coal in which coal particles are depressed and gangue particles floated, was developed as an alternative process to minimise the sulphur content in the coal.

Environmental Performance Assessment of Froth
2020-12-15 energy used in the two-stage flotation process is infinitesimal compared to the energy recovered in the process through the generation of additional coal, and results in only a 0.025% increase in the annual greenhouse gas emissions. The implementation of the two-stage flotation would also result in reduced water losses in comparison to conventional

Optimization of Reverse Cationic Flotation of Low
2017-9-19 Due to gradual depletion of high-grade iron ores, there is a need to investigate the treatment of low-grade iron ores. Current procedures are time and cost intensive. Batch laboratory scale reverse cationic flotation was employed to concentrate low-grade Fe ore, found in fluorspar tails in the form of hematite. This study used two types of depressants (soluble starch and dextrin) and two types ...
