Jun 08, 2016 The flotation reagents can be added in a feed-forward fashion based on the plant raw coal tonnage. Automatic feedback control of the flotation reagent addition rates has been lacking due to the unavailability of sensors for determining the quality of the froth cell tailings. Expensive nuclear-based sensors have been tried with limited success
Jun 08, 2016 Mechanized coal mining techniques generate large amount of fine particles that have to be recovered in coal washing plants. Fine coal processing has always been a problematic and costlier than the cleaning of coarse coal (Andrew Mohns 1997).Froth flotation technique is an effective and best available technique for cleaning fine coal with particle size less than approximately 0.5 mm (Bensley

Aug 09, 2012 Reverse flotation studies on magnetite samples have revealed that the use of starch as a depressant of Fe-oxides has a hydrophilic effect on the surface of Fe-bearing silicates and significantly decreases Fe in the silica-rich stream when used in combination with an amine (Lilaflot D817M). In this study, the effect of reverse flotation on the optimization of products obtained from magnetic
Jan 01, 2021 The flotation of oxide ores, in which sulphidisation precedes flotation, is sometimes used as an alternative to leaching, but generally produces low recoveries (Kongolo et al., 2003, Tijsseling et al., 2019). Indeed, flotation recoveries for oxide ores are around 60% for the copper and around 45% for the cobalt (Fisher and Treadgold, 2009)
