A mixer 3 is fed with coal fines as particles smaller than 5 mm in size, which have a volatile matter content lower than 15 %, originating from a hopper 1 and with lignosulphonate originating from a storage vessel 2 to be used as binder in a proportion of 3 % to 20 %, preferably from 5 % to 8 %, of the weight of the coal and, after agglomeration in a press 5, the agglomerates are subjected to a first heat treatment between 150 and 300 DEG C in a tunnel oven 8 and then to a second heat treatment at 1000 DEG C in a coking oven 10. <IMAGE>
