含锌电炉粉尘处理工艺现状及发展
Treatment Technology and Development of Zinc Electric Arc Furnace Dust
摘要
Abstract
The properties and utilization status of zinc electric arc furnace (EAF) dust at home and abroad were ana lyzed and summarized.The EAF dust in traditional processes have their own limitations.Landfill method can't use the valuable metals in the EAF dust.The requirements of lead and zinc in EAF dust recycling in steel plants are strict and zinc concentration is bad for ironmaking and steelmaking process,thus this recycling process cannot be large-scale.It has a small consumption but long process and serious equipment corrosion so that it is hard to be large-scale in industry using hydrometallurgical methods.And it is of high energy consumption and has serious environmental pollution using pyrometallurgical methods although it has many advantages such as high efficiency,simple operation,high dezincing rate and strong adaptability to raw materials.New processing technologies have the advantages of high dezincification rate and more environmental protection,such as microwave,vacuum metallurgical technology,aluminum bath melting method and so on.However,they are hard to be commercialized in industry due to the large equipment investment and the immature technology.Transformation of roasting-separation technology with the advantage of short process and feasible operation is the future utilization direction of zinc EAF dust.关键词
