Abstract: Equipo y procedimiento de enfriamiento y separación de escorias de aluminio que comprende una bandeja de extracción de escorias para recoger las escorias de aluminio desde la puerta de un horno de fusión, un conducto y un elevador vibrante que transportan la escoria hasta un trómel de refrigeración, que está dotado de un cuerpo con un espacio interno limitado por una pared interna configurada poligonalmente y por una cámara de refrigeración, provocando la separación de la fracción de metal y de la fracción de óxido de las escorias gracias al choque con la pared interna durante el giro del cuerpo del trómel de refrigeración y al enfriamiento de la misma, para posterior recogida y aprovechamiento de la fracción metálica. Finalmente, la fracción de óxido es aspirada por un equipo de filtrado para su posterior tratamiento como residuo.

Abstract: A process (10) for the treatment of a lithium slag, the process comprising the method steps of: (i) Passing the lithium slag to an activation step (14) in which the lithium slag is heated to an elevated temperature of less than about 250 °C in the presence of an alkali (16); (ii) Passing the activated product of step (i) to a hydrothermal synthesis step (22) in which the activated product is heated at an elevated temperature for a period of time, thereby producing a wet sludge containing crystalline, synthetic zeolite; and (iii) Passing the wet sludge from step (ii) to a solid liquid separation step (24) whereby a zeolite product (38) is produced.

Abstract: 本发明涉及一种熔融铜渣贫化-侧顶复合吹熔融还原一体化方法，属于铜渣综合利用领域。具体步骤为：（1）熔融铜渣由加料口加入到贫化熔炼区，喷吹富氧燃料将铜渣升温；（2）贫化剂由贫化剂加料口加入熔融铜渣中，在机械搅拌或气体喷吹搅拌形成的涡流作用下进行涡流贫化，贫化得到的冰铜由铜锍出口排出返回铜熔炼主流程；（3）贫化渣溢流到还原区，然后将造渣剂和还原剂加入到贫化渣熔池中，同时通过顶部喷枪喷富氧燃料，并燃烧熔融还原的CO，对熔池进行提温维持热平衡，在机械搅拌或气体喷吹搅拌作用下进行涡流熔融还原；（4）还原得到的含铜铁水由铁水出口排出，还原渣由出渣口排出。本发明提供了一种熔融铜渣贫化-侧顶复合吹炼还原一体化方法的新思路，可实现铜渣中铜、铁有价组元高效回收，高值化无渣化100%利用，同时实现了对铜渣余热协同利用。

Abstract: Method for obtaining iron concentrate from metallurgical slags from steel production, containing at least 10 mass % of Fe, consists in their gradual crushing and grinding to a granulate with the particles of maximum grain size 1.0 mm, and a subsequent magnetic separation of the magnetic fraction contained in the granulate, while prior to commencing the magnetic separation, the granulate is mixed with water in the ratio of 1 mass portion of granulate to 10 to 100 mass portions of water to obtain a well mixable slurry which, after mixing and under continuous stirring, is subjected to magnetic separation for 2 to 30 min. with a co-action of ultrasound with a frequency of 20 to 40 kHz. Separated magnetic fraction is dried to a constant mass, and an iron concentrate with a content of 20 to 80 mass % of Fe is obtained. Alternatively, prior to mixing with water, the granulate may be subjected to calcination at a temperature of 600 to 1000 °C for at least 60 min. In order to increase the efficiency of this method, the residual fraction not captured by magnetic separation may also be subjected to calcination under the same conditions, and after mixing with water, either alone or in a mixture with the new granulate, the resulting slurry is subjected to repeated magnetic separation with the co-action of ultrasound.

Abstract: Described here is a method for recovering stainless steel from stainless steel slag, wherein the method comprises providing stainless steel slag, subjecting the stainless steel slag to dry milling followed by classifying the milled stainless steel slag to at least two fractions based on particle size characterised as small and middle fraction based on the particle size. The small and middle fractions are individually subjected to magnetic separation to separate a magnetic fraction from a non-magnetic fraction. The magnetic fractions are subjected to further separation to obtain particles with concentrated amount of stainless steel, which are subsequently recovered.

Abstract: Described is a process for the simultaneous treatment of residues of the non-ferrous metallurgical industry, in particular Waelz slag and residues deriving from thermal fuming processes of jarosite, goethite or KSS slag, comprising the following steps: - possible initial pre-treatment (A) of the material to be treated, to obtain homogeneous particle size characteristics; - thermal pre-treatment (B) by the addition of ammonium sulphate (or nitric acid and/or sulphuric acid mixed with ammonium sulphate or with another reagent capable of promoting a reaction with the Waelz slag which makes it possible to obtain firstly the formation of the reaction intermediate ammonium hydrogen sulphate, (NH4)HSC>4 and, subsequently and in sequence, the formation of soluble iron and manganese sulphates and the development of ammonia) and gradual increase in temperature from ambient temperature to a final temperature in the range 200 °C to 600 °C, in a neutral/oxidising environment, to obtain the conversion of the iron, and manganese if present in the material, into compounds such as iron sulphates, and, possibly, manganese sulphates, soluble in water, with the formation of ammonia; and - hydrometallurgical treatments (C), according to the following sub- steps: - addition of water and mixing, - correction of acidity up to a pH of 2 to 8 in an oxidising environment, to obtain the precipitation of the iron in the form of mixed oxyhydroxides. The invention also relates to the use of the precipitate thus obtained, after separating from the solution and purification, for the production of pigments based on iron oxide.
