摘要： 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. In other embodiments, various compositions of the reducible mixture and the formation of the reducible mixture provide one or more beneficial characteristics.

A hearth 20 is movable within the furnace housing 11 in a direction through the drying/preheat zone 12, then the conversion zone 13, then the fusion zone 14, and then the cooling zone 15. A separation barrier 30 is positioned within at least a portion of the conversion zone 13, the separation barrier 30 separating the conversion zone 13 into a combustion region 32 and a reducing region 31 with the reducing region 31 adjacent the hearth 20 and the combustion region 32 adjacent the reducing region 31 and spaced from the hearth 20.

摘要： Systems and methods for use in processing raw material (e.g., iron bearing material) include a linear furnace apparatus extending along a longitudinal axis between a charging end and a discharging end (e.g., the linear furnace apparatus includes at least a furnace zone positioned along the longitudinal axis). Raw material is provided into one or more separate or separable containers (e.g., trays) at the charging end of the linear furnace apparatus. The separate or separable containers are moved through at least the furnace zone and to the discharging end where the processed material is discharged resulting in one or more empty containers. One or more of the empty containers are returned to the charging end of the linear furnace apparatus to receive further raw material.

摘要： Apparatus, methods and systems are used to separate fines from objects of a feed mixture being processed (e.g., iron bearing pellets, chips and dust). For example, at least a portion of an endless belt defining a channel is movable up an incline relative to horizontal (e.g., an incline that is at an angle relative to horizontal that is greater than an angle of repose associated with the objects, but less than an angle of repose associated with the fines being removed). Further, obstruction elements may be used on the endless belt to impede the flow of the fines down the incline.
