Investigation of mechanisms for the control of coal and pyrite surfaces prior to fine coal flotation is an important aspect of the project objectives. Large quantities of coal samples have been procured from six major seams. Samples of the same coals are also to be supplied to the University of Pittsburgh for selective agglomeration research.
Factors of importance in the ntilization of coal fines are mentioned, and the results of flotation tests on coal fines from three important coal seams in New South Wales are presented. INTRODUCTION Economic utilization of fine coal is an important problem in the Australian coal industry, particularly as the proportion of fines mined is increasing...

Jul 01, 2020· The concomitant clay minerals in coal commonly have adverse effects on the coal flotation. In this work, the regulation of coal flotation by cations (Na + and K +) in the presence of clay was investigated to abate this deterioration.It was observed by SEM-EDS that the clay particles coating on the coal surface in low pH condition, which significantly reduced the hydrophobicity of coal.
