Abstract

The invention discloses an efficient aluminum ash separating agent, which comprises the following components by weight: 40%-42% of sodium chloride, 40%-42% of potassium chloride, 8-12% of sodium fluoroaluminate, 3%-5% of alumina and 3%-5% of calcium fluoride. Through the above-described manner, the efficient aluminum ash separating agent provided by the present invention can improve the recovery of aluminum in aluminum ash, reduce energy consumption and waste and reduce costs, and is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of aluminum ash separation, in particular to a high-efficiency aluminum ash separation agent. Background technique [0002] During the aluminum production process, most of the impurities in the aluminum liquid, the added covering agent, the residue after the action of the refining agent, and the compounds produced when the liquid aluminum reacts with the gas are mixed together to form aluminum ash. Aluminum ash is an industrial waste residue with large output and serious pollution, and it is also an important secondary resource of aluminum. [0003] At present, the recovery rate of aluminum ash treatment is low, and additives, such as zinc chloride, are mainly used to keep the recovery rate of aluminum ash at about 65%-70%. However, this method generally consumes a lot of energy, wastes a lot, and is harmful to the environment. harmful. Contents of the invention [0004] The technical problem mainly solv...
