Abstract
ABSTRACT A high ash (38%) Illinois coal was studied. Up to 37% by weight coal flotation recovery was observed at a pH of 5.Even small amounts of humic acids (70 ppm) were observed to completely depress the flotation recovery of the coal. The humic acids also decreased the zeta potential of the coal and a naturally occur ring pyrite. The addition of O-ethyl xanthic acid enhanced the flotability of coal as well as mineral matter, the increase in flotability of coal being greater than that of pyrite at low dosages of xanthic acid, the heating value recovery ratic was observed fee increase with the xanthic acid amount added, up to 79% Btu recovery was obtained. The humic acids adsorption on coal was also investigated.
