For the purpose of getting a base as to thorough utilization of domestic pyrite which contains a small amount of cobalt, copper and zinc, the sulfatizing roasting process which is based upon the preferential sulfatization by fluidized-bed reactor which has a capacity of 5 kg per day was studied. This paper describes the results of experiments, showing that it is useful to treat this kind of pyrite to produce water soluble sulfate of cobalt, copper and zinc while retaining most of iron in insoluble oxide from, and suggesting one of possibilities considered in treating the final reside after extraction. Theoretical considerations are given on the gas composition and its distribution in the furnace, and the reacting temperature and the hold-up time of the solids in the furnace.
