4.1 Process Overview 4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or open-pit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions.Web

Iron ore sintering is an energy-intensive process that converts iron ore fines into an agglomerated porous mass. Sintering plays a prominent pre-processing role in blast furnace smelting operations because of its unsuitability with finer ores. In recent years, the conventional sintering method using coke/coal is being gradually discarded due to …Web

Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat.

Abstract: The sintering process is a thermal agglomeration process, and it is accompanied by chemical reactions. In this process, a mixture of iron ore fines, flux, and coal particles is heated to about 1300 C– 1480 C in a sinter bed. The strength and reducibility properties of iron ore sinter are obtained by liquid phase sintering.Web
