    摘要: PROBLEM TO BE SOLVED: To provide a reduction treatment, such as control of the size of an iron nugget, control of micro-nugget formation and control of sulfur content in an iron nugget, in production of a metallic iron nugget.SOLUTION: A method and system for producing metallic nuggets includes providing reducible mixture (e.g., reducible micro-agglomerates; reducing material and reducible iron bearing material; reducible mixture including additives such as a fluxing agent; compacts, etc.) on at least a portion of a hearth material layer. In one embodiment, a plurality of channel openings extend at least partially through a layer of the reducible mixture to define a plurality of nugget forming reducible material regions. Such channel openings may be at least partially filled with nugget separation fill material (e.g., carbonaceous material). Thermally treating the layer of reducible mixture results in formation of one or more metallic iron nuggets.
