The experiment showed that iron grade of siderite from Xinjiang is lower and there is CaO content higher for 7.87% and SiO2 content lower only for 0.79% in it. Therefore, the sintering study to siderite as the main raw material is with additional needs amount of silica or ore containing higher SiO2 to achieve the required alkalinity of blast furnace production. Sinter can be used in small blast furnace with higher fuel consumption and drum index from 56% to 57%.
