摘要:
Effective beneficiation of fine coal; i.e., coal sized below 1 mm, either by means of deashing or dewatering, or a combination of both, is mainly dependent upon the following factors:

摘要:
The effectiveness of two-stage reverse flotation for desulfurization of coal is significantly dependent on the microstructural features of the heavy mineral fractions in the coal seam. This dependence has been evaluated by a systematic mineralogical analysis of the flotation products obtained from both Eastern (Lower Freeport) and Midwestern (Illinois No. 6) coals by SEM/EDAX and TGA. Comparison of the results from this detailed analysis suggests that the effectiveness of desulfurization during reverse flotation is determined by the relative degree of pyrite association with silicate minerals and carbonaceous material. When locked pyrite contains a higher relative percentage of silicate minerals desulfurization by reverse flotation is more effective.
