1 Introduction. In heavy clay ceramics, the term "reduction" can be explained as the removal of oxygen from the clay material. Generally, the oxygen-richest iron oxide, haematite (Fe 2 O 3), is responsible for the intense red colouring of brick.If you break up the compound by removing oxygen, magnetite (Fe 3 O 4), an oxygen-poorer iron oxide, is formed, the colour of which is …In order to explore the efficacy of iron ore–coal composite pellets over ordinary green pellets, indurated pellets, briquettes as well as standard charging of material in the form of concentric layers of iron ore and coal fines, or their mixture, these pellets were tested at 1,150 °C in a 7 tons per day (7 tpd) pilot tunnel kiln.
