Froth flotation machine of coal

Flotation tests were also conducted with Appalachian coals for comparison;Iowa coals did not respond as well to froth flotation as Appalachian coals. Although Iowa coal floated very slowly and incompletely with only a frother (methyl isobutyl carbinol or MIBC), it floated rapidly when a large dosage of an oily collector (No. 200 LLS fuel oil
