ABSTRACT:
An apparatus and process for treatment of metallized iron ore produced by direct reduction techniques principally for use in various iron and steelmaking furnaces. The apparatus and process receives the product from a direct reduction facility consisting of hot metallized fine sizes of reduced iron ore such as from a fluidized bed reactor system that can be combined with metallized iron ore pellets or like agglomerates from other types of direct reduction reactors. The present invention involves dry and wet treatment and handling apparatus and procedures wherewith the hot metallized fine sizes, optionally including metallized pellets or agglomerates, are rendered immune from reoxidation and degradation for unlimited periods of time whether in open storage or during transport, whereafter the stabilized product can be readily used in various types of iron and steelmaking furnaces.
