Chapter 11: Dense Medium Separation (DMS) | Engineering360

Jan 01, 1991· The LARCODEMS dense medium separation technique can readily produce a 'cleans' coal fraction of 2–5% ash content and a 'middlings' fraction of less than 10% ash, from coals containing up to 50% ash. The combined energy content of the cleans and the middlings can represent over 98% of that of the coal fed to the separator.
