Metallurgical and Electronic Waste Recycling

ABOUT THE COURSE: The course provides an insight into modern recycling routes for recovering valuable metals and materials from metallurgical and electronic wastes. The fundamentals of recycling are blended with the processes to provide emphasis on the application of the processes. With a wide variety of raw materials and dedicated recycling routes, concepts of material extraction and recovery will be discussed. Importance of material pretreatment and environmental benefits of materials recycling have also been described.
