Abstract: A treatment method for a magnesium slag, comprises: Step a, producing magnesium particles and a crude solution of magnesium slag by digesting and sifting a magnesium slag; Step b, filtering the crude solution of magnesium slag sifted in Step a, so that mixed chlorides are obtained after a moisture in a filtrate is removed; Step c, obtaining a high purity magnesium oxide by dissolving a filter residue obtained in Step b via an ammonium sulfate method and a magnesium precipitation reaction as well as post-treatment. With the method, utilization of magnesium slag can reach up to more than 90% with a higher recycling rate, while the discharge of solid wastes can be reduced greatly which solid wastes are less contaminative to the environment, so that the contamination to the environment is greatly reduced and the required energy saving and emission reduction are also achieved.
Abstract translation: 一种镁渣处理方法，包括：步骤a，通过消化和筛选镁渣生产镁颗粒和镁渣粗溶液; 步骤b，过滤在步骤a中筛分的镁渣的粗溶液，使得除去滤液中的水分后得到混合氯化物; 步骤c，通过硫酸铵法和镁沉淀反应以及后处理溶解步骤b中得到的过滤残渣，得到高纯度的氧化镁。 采用这种方法，利用镁渣可以达到高达90％以上的循环利用率，固体废物的排放量可以大大降低，固体废物对环境的污染较少，从而对环境的污染是 大大减少，也实现了节能减排。

Abstract: A method comprises sorting and removing impurities from magnesium alloy waste material, and cleaning and drying said material, the cleaning being high-pressure rinsing, pickling, and water washing, performed in sequence. The method employs high-pressure rinsing during the pretreatment of magnesium alloy waste material; the cleaning effectiveness is excellent, the effectiveness of the removal of impurities from the surface of the magnesium alloy waste material is much better than in conventional processes, and the amount of clean waste material can exceed 90% of the total amount of processed waste material; the clean magnesium alloy waste material obtained from the pretreatment method may be used as the entire raw materials for casting national-standard alloy ingots, the addition of costly high-purity magnesium is unnecessary, and the amount of alloy raw material that must be added is significantly reduced; during processing, little waste material is lost, costs are low, and efficiency is high.
