Flotation of coal with latex emulsions of hydrocarbon,
Abstract. Employment of a latex emulsion prepared from a hydrocarbon, animal or vegetable based oil with a hydrophobic water-in-oil emulsifier and a hydrophilic surfactant in the froth flotation of coal improves coal recovery without increasing the ash content.Intensification mechanism of oxidized coal flotation by,,mal flotation procedure for oxidized coal were also studied by Ahmed and Drzymala [15]. Xia et al. found that oxidized coal flotation can be achieved by using oxidized diesel oil also due to the hydrogen bonding with the polar part of oxidized coal surface and oxidized diesel oil indi-cated by Fourier transform infrared spectroscopy [16].Flotation Reagents - Mineral Processing & Metallurgy,08-06-2016· Coal tar creosote oil.
