A method and an installation (10) for removing slag allows both slag removal and metal recovery from slag (60) to be performed quickly and easily. The risk of slag fires is reduced.

A method of recovering cobalt and nickel includes the steps of: adding alkaline to an acidic solution containing aluminum together with cobalt and nickel, adjusting pH of the acidic solution to 5 to 7, and converting the cobalt, the nickel and the aluminum into hydroxides thereof; recovering the hydroxides by solid-liquid separation, mixing the recovered hydroxides with an alkaline solution, and leaching aluminum contained in the hydroxides under a liquid condition of pH 8 or more; and recovering a cobalt hydroxide and a nickel hydroxide that aluminum is separated therefrom by solid-separation on a leachate.

A volatiles consuming eductor system for coated scrap metal furnaces with separate delacquering and melt chambers. Motive gas is forced through an inlet into a mixing chamber in a direction opposite a suction port, creating a Venturi that draws gases from the delaquering chamber through the mixing chamber. The motive gas and the drawn gases mix and are forced through a discharge port, ignited, and injected into the melt chamber to help heat the melt chamber. A computer monitors process conditions and controls a regulator that adjusts the motive gas flow in response to those conditions.

In some examples, the product comprises a container, shot blasted pieces of aluminum alloy wheels and an alloying supplement. In some examples, the product also comprises an indication on the container of a composition estimate of the combined shot blasted pieces and alloying supplement. In other examples, the indication and/or the alloying supplement may be provided by a company in the business of providing alloying supplements.

Provided is a method for processing lithium ion battery waste, which can effectively precipitate aluminum ions and iron ions in the solution by neutralization and relatively easily separate the precipitate. The method for processing lithium ion battery waste includes: a leaching step of leaching battery powder in an acid, the battery powder containing at least aluminum and iron and being obtained from lithium ion battery waste, and removing a leached residue by solid-liquid separation to obtain a leached solution containing at least aluminum ions and iron ions; and a neutralization step of adding phosphoric acid and/or a phosphate salt and an oxidizing agent to the leached solution, increasing a pH of the leached solution to a range of 2.0 to 3.5, precipitating the aluminum ions and the iron ions in the leached solution as aluminum phosphate and iron phosphate, respectively, and removing a neutralized residue by solid-liquid separation to obtain a neutralized solution.

A method for recovering and recycling lithium battery components comprises shredding used batteries into fragments, recovering electrolyte from the fragments, aspirating the fragments to remove separator membrane fragments from other solid materials, magnetically separating the cathode fragments from the non-magnetic anode fragments on a rare earth roll separator; thermally removing binder and carbon from the cathode fragments, recovering delithiated cathode active material; relithiating the delithiated cathode active material, recovering aluminum foil from the cathode fragments; removing cathode active material from the anode fragments, and recovering copper foil from the anode fragments.

A method for separating a rare earth metal. The method comprises contacting a solution comprising a rare earth metal with a first column to separate the rare earth metal into light, medium, and/or heavy rare earth metals; and contacting the light, medium, and/or heavy rare earth metals to with the second column to separate the light, medium, and/or heavy rare earth metals into individual rare earth metals. A method for extracting rare earth metals from a solution comprising contacting the rare earth metal with a plurality of resins. A method of extraction rare earth metal and lithium from a dynamic pad and permanent pad.

In order to provide a method and device that allow sorting of light-alloy aluminium scrap, the disclosure proposes a method for sorting aluminium scrap and alloys thereof wherein the aluminium scrap is fed to a measuring station, where the electrical conductivity of each aluminium part is measured, and, depending on the result of the measurement, the part is transported further on a dedicated path.

The presently disclosed subject matter is directed to a method of hydrothermally treating metallic packaging, metallic labeling material, and scrap metal items. Particularly, the disclosed method initially comprises providing a metallic starting material. The metallic starting material is introduced to a reactor and processed at elevated temperature and/or pressure for a desired amount of time. As a result, the metallic portion of the starting material separates into a distinct layer that can be removed from the remainder of the starting material.

A method for recycling metal scraps, particularly aluminum scraps, is provided. In the method, an amount of metal scrap, particularly aluminum scrap, is provided in the form of a plurality of separated split lots. A composition analysis is carried out for each split lot and an item of composition information based on said composition analysis is associated with each split lot that has been analyzed. Also provided is a device configured for carrying out said method.
