Simultaneously Roasting and Magnetic Separation to Treat
During the roasting process, siderite (FeCO 3) transforms to magnetite (Fe 3 O 4) along with producing carbon monoxide (CO), but hematite (Fe 2 O 3) needs CO to reduce into magnetiteThe process of simultaneously roasting and magnetic separation was developed to treat the low grade siderite and hematite ores without adding any reductantincrease this maximum capacity for a single roasting line up to 1,800 t/d of concentrate From an economic and technical standpoint, this throughput can only be achieved for one line by applying circulating fluid bed technology In similar applications, the throughput eg in whole ore gold roasting plants can reach up to 3,800 t/dPYRITE ROASTING, AN ALTERNATIVE TO SULPHUR BURNING
