To produce sinter, a mixture of sinter ore, siderite, limestone and ironbearing waste products rich in iron (like scale, etc.) is used as a raw material. The mixture is also pelletized and sintered.

Siderite ores are subdivided into crystalline siderite ores and clay spathic ironstones. The average iron content is 30–35 percent. After roasting, as a result of the removal of CO 2, siderite ores become industrially valuable finely porous ironoxide ores (usually containing up to 1–2 percent manganese; sometimes up to 10 percent).

Domestic ores for sintering in China are primarily magnetite concentrates. Many Chinese sinter plants use imported ores and domestic magnetite concentrates in their blends, and the level of imported ores varies significantly from mill to mill. Compared to the sintering of Chinese domestic ores, higher productivity, lower coke consumption
