this book provides a fascinating study of the very important emerging field of direct reduction in which iron ore is directly reduced in the solid-state, using either natural gas or non-coking coal, to produce a highly metallised material, referred to as sponge iron this intermediate product is subsequently melted in electric arc furnaces or induction furnaces
the operation is similar to the standard cone crushers, except that the size reduction is caused more by attrition than by impact the reduction ratio is around and as the product size is relatively small the feed size is limited to less than mm with a nip angle between and the gyradisc crushers have head diameters from
As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore by counterflowing gases that have a high and CO content. these gases react with the iron oxide in the iron ore and convert it to metallic iron, leaving and CO
