Blast-furnace Chemistry and Titanium Problems. In a blast furnace, hot air is blown through a mixture of iron ore, coke and fluxes such as limestone, creating conditions suitable for the reduction of iron oxide to metallic iron. The principal reducing agent is carbon monoxide, formed by reaction of carbon in the coke with oxygen in the air blast.
