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 ...

(2) AAS Measurement of magnesium: Repeat procedure (1) using the magnesium stock solution and the unknown samples. Remember that the element selection on the AA (the drop down box) has to be changed to measure magnesium. (3) AAS Measurement of iron: Use a 5.0mL pipet (or a graduated cylinder, if you prefer) to add 0, 5.0, 10.0, 15.0, 20.0,
