The scrap aluminum used in this process mainly comes from the dismantling of electronic waste. This process primarily uses electricity and the combustion of various fossil fuels to melt aluminum-containing waste materials. After melting, slagging agents and refining agents are added, and various floating slags produced by melting are physically removed. The refined scrap aluminum is then cast and sawed into aluminum rods. During the processing, slagging agents and refining agents are used to remove impurities from the molten aluminum. The required purity of sodium hydroxide is 100%, mainly to remove organic impurities. The main components of the slagging agent are sodium fluorosilicate, sodium chloride, and potassium chloride, while the main component of the refining agent is cryolite. Electricity and natural gas are used to provide the heat required for melting. The processing generates wastewater containing anthracene oil, COD, ammonia nitrogen, oil pollutants, and phenol, as well as exhaust gas containing sulfur dioxide, nitrogen oxides, hydrogen chloride, and fluorides, which are treated and then directly discharged into the atmosphere. The waste aluminum raw materials used are pure aluminum scraps, which have undergone sorting and baling.
