Abstract
A pilot scale investigation was carried out to establish the benefits of oil pretreatment of fine coal prior to filtration. Oil addition results in the formation of aggregrates held by pendular oil bridges and the filtration of a treated slurry is shown to depend on the amount of oil and the agitation intensity during pretreatment. Experimental work aimed at comparing performance against the traditional method of using polymeric flocculants shows that higher cake throughput can be obtained at a lower ash value with no significant deterioration in cake moisture.
