It has now been demonstrated that iron-bearing materials can be roasted as effectively as by any previously known method, and at a much lower cost. Heretofore the basic concept behind most magnetic roasting processes has been the idea of heating iron ore to a temperature of 800° to 1100°F in a strong reducing atmosphere, preferably either carbon monoxide or hydrogen.
Suspension roasting furnace was used as the reactor of magnetic roasting of fine grained siderite, and the N2 was used as the conveying gas. The results show that, the siderite ore be roasted at the conditions of gas velocity is 1.7m/s, and the roasted time is 12.35s, according to magnetic separation can obtained iron concentrate grade is 65.04%, and recovery rate is 93.03%.
By oxidation at 200-400°C the over reduced ore becomes a uniform magnetic product and consequently it gives a high recovery of iron by magnetic concentration. 4. Although this is a Iaboratory result, the auther believes that if the ore is reduced with coke oven gas at 600-700°C and quenched in air at about 400°C magnetically uniform product is obtained.
