Coal is hydrophobic and is separated from hydrophilic gangue minerals eg pyrite in the flotation However the natural hydrophobic property of pyrite makes coal–pyrite separation difficult as significant amounts of pyrite are recovered in the froth along with the coal...

articleosti6663644 title Method for the froth flotation of coal author Hansen R D and Klimpel R R abstractNote A method is described for recovering coal from a coal ore containing coal and noncombustible mineral matter which comprises the step of floating coal in a frothing aqueous medium containing an oxygen containing compound of the formula Rsub 1Rsub 2 wherein RFurther Details
1 Introduction Conventional froth flotation for fine coal cleaning suffers mainly from two problems i a lack of selectivity for fast floating high rank coals due to the flotation of middlings and entrainment of mineral fines in the froth and ii low recoveries for heavily oxidized or low rank coals due to poor adhesion between bubbles and particlesFurther Details
Froth flotation is widely used to treat fine coal particles This process is based on differences in the surface hydrophobicity of coal and gangue Coal is a naturally hydrophobic material and the hydrophobicity can be enhanced by adding collector at the conditioning stageFurther Details
Effect of Size of Mineral Grain on the Flotation of Pyrite Sample mixture No 4 used in these tests was prepared in a manner similar to sample mixtures Nos 1 2 and 3 except that it was crushed to pass a 48mesh Tyler standard screen A partial analysis of the mixed and crushed sample showed 1070 per cent iron and 018 per cent copperFurther Details
silica and pyrite particles which are floated at three different bubble sizes The bubble sizes in this investigation 1 to 2 mm are more or less the same as those encountered in many current industrial machines In coal flotation fine bubbles also improve separation as they intensify the difference in the kinetics of the coal fromFurther Details
Normally pyrite should float well under typical sulphide flotation regime However surface alteration such as tarnishing due to geochemical actions can be one of the inhibiting factorsFurther Details
Another important application is to reduce ash in fine coal and to remove fine pyrite from coal The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore At present nearly 2 billion tons of ore inFurther Details
