The properties of metallurgical coke are critical to the performance of the blast furnace for iron making.
While extensive work has gone into understanding the relationship between the properties of coke and its
behaviour in the blast furnace, the heterogeneous nature of coke makes understanding these relationships
difficult. Herein we report the use of a laboratory produced coke analogue to examine the effects of
minerals on the reactivity behaviour of coke in a pseudo-CRI test. The effects of a range of minerals on
the reactivity of the coke analogue are demonstrated and the effects of binary combinations of silicon and
iron bearing minerals are examined.
