Currently there is considerable interest in the production of DRI in
Western Australia to take advantage of intense interest from the Asian
market. Most DRI is produced using gas-based processes and is used as a
feedstock in electric arc steel furnaces, otherwise known as mini-mills.
This paper critically examines the technical and economic issues of
various gas-based DR processes available today and recommends the
most effective and attractive processes suitable for Western Australian
iron ores.
