Which kind of catalyst is suitable for rotary roasting of hematite ore magnetizing?

Mehrdad Rashidzadeh @Mehrdad-Rashidzadeh

21 January 2025 0 2K Report

I saw a process that a ring like catalyst made by chisel, alumina refractories and some other material is located in the middle of a rotary furnace to increase the amount of Co that produced during the roasting and magnetizing of the iron ore.

I need to know what is this catalysis and how can i find or make it? is there any helpful references?
