Production of Copper and Zinc Oxide in the Process of Brass Scrap Recycling

"Industrial scale testing was performed in the plant-site of Bor Company. Charging sample was from 4-5 tons for each particular test. All operations in industrial scale investigations were carried out in one furnace. For the aim of successful realization of experiments, and primarily for safety and prevention the risk of toxic contamination the working environment, a plant was designed and constructed for cooling and wet dedusting of gases formed during smelting process, zinc removal and flame refinement of molten metal. For the requirements of industrial investigations a complete plant for cooling and wet dedusting of gases has been constructed for brass scrap processing. In this plant, the original ultra-sonic water spraying devices have been installed. The efficiency of such simplified system for gas treatment has been 98,6%. Introduction Permanent development of techniques and technology causes formation the considerable quantities of secondary raw materials that are much more relevant as the raw material base for many metals. Due to a fact that large quantities of metal, are concentrated in the waste materials, large consideration is given to this topic, and numerous technologies for this waste recycling are developed in the world nowadays. High energz price and permanent increase of metal price on the world market have made that secondary raw material tretament, for the aim of various metals production, becomes more and more relevant in the world. In comparison of metal production using enrichment and metallurgical treatment of primary raw materials, the non-ferrous metals production from secondary raw materials has a range of advantages, as well as: - Low level of capital investments, - High technological recovery of qualitative secondary raw materils, - Considerably low consumption of energetic resources regarding to the treatment of primary raw materials (ore and concentrate), - Reduced consumption of unrecoverable mineral resources, - Reduced enviroment pollution [1,6]."
