## magnetic roasting of iron ores

### Roasting (metallurgy) Wikipedia

Sulfating roasting oxidizes certain sulfide ores to sulfates in a controlled supply of air to enable leaching of the sulfate for further processing [citation needed] Magnetic roasting Magnetic roasting involves controlled roasting of the ore to convert it into a magnetic form, thus enabling easy separation and processing in subsequent stepsThese iron ores contain many detrimental impurities and are difficult to upgrade to make suitable concentrates for the blast furnace In this paper, the beneficiation of a lowgrade hematite ore fines containing carbonates with magnetization roasting and magnetic separation was proposed and studiedBeneficiation of an iron ore fines by magnetization One such example is the use of magnetizing roasting followed by the lowintensity magnetic separation technique to recover iron from red mud, [10][11][12] iron ore tailings, [13] and some refractory iron oresMagnetic reduction roasting and magnetic separation of
