Evaluation and Potential Possibilities on Treatment of Metals Practice's Waste

There was demonstrated that source of secondary raw materials for zinc recovery are a dust from copper and steelmaking and zinc cake. The most value from indicated products present follow metals: zinc, lead, tin, copper. According to value of valuable components in raw materials, the most value has dusts from copper smeltery. There is reasonable treat stated products by means of volatilization method in tube furnaces (). High content of halogenides and arsenic complicates zinc recovery by hydrometallurgical method from waelz-fume. There was offered for harmful contaminants removal as the most reasonable method baking. Taking into account volume of generated volume, the most potential for zinc recovery has dust of steelmaking. Throughout the world proportion of zinc recycling is 30 per cents, and in Russia only 4 per cents. Therefore there is need modernization of existing method of Waelz process and fume baking, from the viewpoint of volume growth of zinc recycling for home industry.
