Investigations were made on the use of two synthetic latexes as selective flocculants in the flotation cleaning of coal. The most commonly used latex in the industry contained sodium dibutylnaphthalenesulfonate, which is a biologically ''hard'' emulsifier. It was determined that butadiene-styrene latexes may successfully be used as selective coal sludge flocculants. The most efficient was a latex synthesized using biodegradable emulsifiers--potassium soaps of disproportionated rosin with a small quantity of synthetic fatty acids. Also, it was concluded that the values of the ash level in the flotation concentrate and tailings could be controlled by regulating the latex consumption.
