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 ...
