Effect of slimes on the flotation recovery and kinetics of coal particles
Fuel, 2018 To investigate the effect of slimes on the flotation recovery and kinetics of coal particles, batch flotation and flotation rate tests were carried out using flotation mixtures including slime particles and coal particles within 0.5-0.25 mm, 0.25-0.125 mm and 0.125-0.074 mm size ranges, respectively. Six flotation kinetic models were applied to fit all

Vibroacoustical selective agglomeration of coal slimes
Powder Technology, 1984Abstract Coal slimes from coking coal with an average ash content of about 45% and difficult separation characteristics have been studied. Investigations have also been carried out on two artificial mixtures of gangue and coal of low ash content.

Intelligent Control and Optimization of the Coal Slime Flotation
Advanced Materials Research, 2012The inchoate algorithm for the coal slime flotation control is the feed-forward control to the feed concentration and the reagent quantity. This control model is widely utilized because of the easy realization once the used sensors are reliable. However the control results are usually not so good as it cannot adapt the quality fluctuation of the feed ...
