Abstract

While ultrasonic coal-wash is not entirely new in many countries, it has not yet been practised in India, though it would appear that the relatively high ash and sulfur content of Indian coals would render them particularly suitable for such a washing procedure. In this study, state-of-the-art ultrasonic equipment, spanning the frequency range from, highly-cavitational (<100 kHz), to intermediate (100–200 kHz) to mostly acoustic-streaming dominated (>470 kHz), is used. The present study encompasses ultrasonic aqueous-based and reagent-based coal beneficiation, in addition to the wide frequency range employed. The uniqueness of the work results from these aspects.
