iron ore roasting

When iron ores are roasted at temperatures above about 1500° F the magnetite mineral contained in the ore oxidizes rapidly enough to act as a significant source of heat for the process The fuel value of magnetite burned in this way is about 7000 BTUlb When magnetite is burned hematite is produced
