The coal sample was first agitated in a 1.0-L flotation cell for 2 min, after which the required dosage of the depressant was added. The pulp was conditioned for 3 min, and the collector and frother were added and stirred for 2 min and 0.5 min, respectively. Air was introduced, and the sample was collected for 3 min.

One method to evaluate the technical efficiency of flotation is the release analysis. In this method the separability of the minerals is pushed, by repeated cleaning of the concentrate, to that given by liberation of the minerals. The separation usually achieved may then be compared with this practical limit. The method is elegant due to the

ABSTRACT: Fine coal slimes (less than 0-0.2 mm) present great difficulty in cleaning. Their flotation ability depends on their size and physico-chemical characteristics. In particular, the degree of metamorpbism of the coal, and the proportion and ash content of super-fine coal particles (less than 50 pm) produces quite a strong

The flotation process can be more effective in desulfurization of the coal when the majority of the sulfur content of the coal is pyritic sulfur. In addition, it was believed that the higher percent of pyritic sulfur in the total sulfur content of the coal prompted the production of lower sulfur content clean coal, and the column flotation method can produce a cleaner coal product than the conventional flotation.
