Method of and the device for roasting dry ore particles in a fluidized-bed layer

摘要

the invention relates to a method of roasting ore particles comprising carbon and / or sulphur, which in order to wyprau017cenia particles is introduced into the reactor (11).in addition, introduces oxygen containing gasthe particles swelters in fluidised bed at a temperature of from 500 to 1000u00b0c by at least 10 seconds and with pyrites particles are removed from the reactor.these particles are characterized by a water content of up to 2 wt%. and are wtryskiwane pneumatically to deposit fluid.
