Fatty acid type ionic collectors were used as an alternative to conventional oily collectors, kerosene, and pine oil mixture in the flotation of coal tailing with 46.1% ash. The conventional collectors could not reduce the ash content of the concentrate below 22%. On the other hand, ionic collectors were found to be significantly better at reducing the ash content down to 13%. It was concluded that despite their lower flotation yield and higher consumptions, certain ionic collectors could be used successfully in coal flotation where cleaner concentrates are required from coal fines with high ash content.
