摘要： The present invention relates to a method and apparatus for separating undesired toxic metals, such as Zn, Pb and Cd, from iron-containing materials by: sintering a mixture of such materials (typically including EAF dust and mill scale) with carbonaceous particles to form sturdy sinter lumps; preheating such lumps in a non-reducing atmosphere, if needed, to achieve an elevated temperature generally above the vaporization temperature of the undesired metals, but below the sticking temperature of said iron-containing lumps (which is typically below the vaporization temperatures of such undesired metals in their oxide form), feeding the lumps at such elevated temperature into a reduction reactor; flowing hot reducing gas through said lumps to volatilize said undesired reduced metals and carry the volatilized metals out of said reduction reactor leaving the iron-containing lumps largely stripped of the undesired metals and ready for discharge and safe and/or useful disposal or re-use, and finally cooling the off gas from the reactor to separate out the resulting solidified unwanted metals (typically in their oxide form resulting from a water quench cooling).

摘要： A method for reducing an iron-containing material to a metalized iron product. The method includes feeding from about 5 to about 25 percent by weight, based on a total weight of iron-containing material having a total iron content of from about 60 to about 85 % by weight and hot coke to a coke dry quenching (CDQ-SP) apparatus. The iron-containing material is reduced in the CDQ-SP apparatus to metalized iron product having a degree of metallization of greater than about 90 % by weight. The metalized iron product is then separated from a quenched coke product.

摘要： A process for extraction of zinc from a material containing one or more iron oxides and zinc oxide includes heating a composite body of the material and a carbonaceous material in a reduction zone. The reduction zone contains a reducing atmosphere at a temperature insufficient to effect melting of the iron in the material but at a temperature and for a time sufficient to form a reductant from the carbonaceous material and to reduce a predetermined amount of the zinc oxide to zinc vapour. The process also includes collecting the zinc vapour and cooling it to form liquefied or solid zinc.
