Title: Improvements in the method of and means for roasting metallic ores
IPC: F27B9/24
Filed: 1922-05-19
Abstract: 205,528. Mackay, H. S. May 19, 1922. Drawings to Specification. Roasting.-A process of roasting ores in a multiple hearth furnace of the kind in which the ore is swept from hearth to hearth by rotating rabbles, consists in isolating the hearths one from another, and controlling the temperatures on and the supply of air to the individual hearths, and the time during which the ore is under treatment. As applied to the roasting of copper ores containing iron, the treatment is effected in two stages, in the first of which, carried out on three hearths of a seven-hearth furnace, a large percentage of copper is converted to oxide and sulphate, while only a small percentage of the iron is combined as sulphate, Suitable temperatures for the three hearths are 420‹ C., 450‹ C., and 490‹ C. respectively. In the second stage on the three succeeding hearths the temperatures are increased, say to 550‹ C., 590‹ C., and 590‹ C. respectively, and the air supply is also increased so that all the iron is converted to insoluble oxide. The seventh hearth is unheated, and on it the ore is cooled in the presence of excess air.
