    • Coal fines are agglomerated by mixing together the coat fines, a phenol-formaldehyde resole resin in alkaline aqueous solution and a curing agentforthe resin comprising one or more esters selected from esters of polyhydric alcohols, carbonate esters and lactones, forming the resulting mixture into agglomerates and drying and curing the agglomerates. A small proportion of a thermoplastics material such as polyvinyl alcohol or an acrylic polymer may be included to improve the surface hardness of the agglomerates, and a small proportion of a material which will improve the coking property and hot strength of the agglomerates, for example finely ground coking coal or bitumen when the coal fines are anthracite fines, may also be included.
