question of the week: what is reduction roasting?

question of the week: what is reduction roasting?

Reduction roasting is the removal of oxygen from a component of an ore, usually through the use of Carbon Monoxide (CO). The CO is typically supplied by mixing a carbonaceous material such as coke or coal with the ore, or by feeding it separately.

An example is the reduction roasting of a hematite containing material to produce magnetite that can be magnetically separated. A second example comes from the Waelz process, where zinc oxide in steel mill waste is reduced to a metallic zinc and volatilized for recovery in the off-gas system.
