ABSTRACT Gold or any desired mineral treated to have a lyophilic surface, is recovered from ore bodies by an agglomeration method in which coal and oil are added to the ground or slurry and contacted in a zone where any agglomerates are kept below 500 microns in size. Subsequently the mix is passed to an agglomeration zone where agglomerates of coal oil and gold or the lyophilic mineral are formed. The agglomerates are separated from the gangue and recycled to the contacting zone until a desired gold or mineral concentration in the agglomer- ates is achieved.
