Fine sulphide ores, particularly flotation blendes and pyrites, are treated, without the addition of any binding agent, with such an amount of water as is just sufficient to convert them from a crumbly to a plastic or spreadable condition, and are then made into granular or vermicular form. The product, preferably without being dried, is passed to a roasting furnace, preferably directly into a zone of fairly high temperature.
