Iron ore sintering and pelletizing are the predominant processes in the iron-making industry [1,2]. During the iron ore sintering process, calcium ferrite phase is believed to be the most desirable bonding phase because it has high reducibility and sufficient mechanical strength [3–5]. The sintering process can be divided into three

When the iron ore is extracted from the mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher’s CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.

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. Before being delivered to the sinter machine, the ore mixture is
