froth flotation of pyrite from coal in ghana

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...

Physical and chemical interactions in coal flotation

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 particles

flotation of coal Hard Pressed Café

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 stage
