摘要： Provided a method for preparing metallurgical-grade alumina by using fluidized-bed fly ash, comprising: a) removing iron by wet magnetic separation after crushing the fly ash; b) reacting the fly ash after magnetic separation with hydrochloric acid to obtain a hydrochloric leachate; c) passing the hydrochloric leachate through macro-porous cationic resin to deeply remove iron to obtain a refined aluminum chloride solution; d) concentrating and crystallizing the refined aluminum chloride solution to obtain an aluminum chloride crystal; and e) calcining the aluminum chloride crystal to obtain the metallurgical-grade alumina. The method is simple, the procedure is easy to be controlled, the extraction efficiency of alumina is high, the production coast is low, and the product quality is steady.

摘要： The invention relates to a method for recycling dust from electric steel plants, originating from the furnaces of secondary-smelting electric steel plants, in which a portion of the dust collected after smelting in the electric furnace is agglomerated in the presence of a sodium oxide source and a carbon source so as to form pellets, and the resulting pellets are subsequently fed into the electric furnace with the scrap.

摘要： The present invention pertains to a method and device for producing reduced iron from iron-making dust comprising iron oxide produced in an iron-making plant, focuses on a rotary kiln reduction method free of the need to pre-treat the dust, and addresses the pursuit of equipment for achieving further enhanced thermal efficiency and stable operation. To achieve the foregoing, the present invention is characterized in that when heating and reducing a carbon-containing molded body in a single enclosed space in which an internally heated rotary kiln and an externally heated rotary kiln are arranged in series and which comprises at least both the rotary kiln interiors, a reduction exhaust gas produced in an externally heated rotary kiln is combusted in the interior of an internally heated rotary kiln.
