Processing of finely dispersed aluminum waste with different content by-product metals
Journal Title: Metallurgical and Mining Industry - Year 2017, Vol 9, Issue 2
Abstract
Chemical dispersing waste recycling method was developed for aluminum alloy. Method of chemical dispersing is the dissolution of small particles of aluminium alloy (chips, small pieces) in alkaline solutions with the formation of precipitate-powder of aluminum hydroxide. The resulting sediment filters and washes by the method of successive decantation. This sediment possesses a complex of unique properties that are difficult to obtain using traditional technologies. Precipitate morphology structure inherits predominantly original alloy and its chemical composition, affects the phase composition of sediment. Control phase composition may exercise through the introduction of necessary additives in the original stage alloy weld. Formed when processing chips of aluminum hydroxide are a source of raw materials for advanced ceramic materials on the base of aluminum oxide for the manufacture of a new class of ceramic materials with unique properties. At the same time the problem of recycling aluminum alloys, including waste disposal, Al-Li alloys involved a number of features that impede this process with traditional technologies.
