The behavior of coal microlithotypes, free mineral matter and pyrite and locked carbominerite particles has been determined in a coal flotation system using quantitative mineragraphic techniques. Two circuit configurations were studied: a rougher-only circuit and a 'Grab and Run' (rougher-scavenger-scavenger cleaner) circuit. A detailed microscopic study has established the flotation response of free coal, coal microlithotypes (locked maceral particles), pyrite, ash, and locked coal-pyrite and coal-ash particles of various sizes for each of the circuit variations and reagent changes.
