ABSTRACT:
The present invention relates to a process for the production of metal alloys, metal oxides and slag-based products, such as mineral wool, from industrial waste materials. More specifically, the present invention relates to a process for recycling industrial waste materials into valuable commercial products, including, pure metals, metal alloys, metal oxides, and a molten slag comprising non-reducible metal oxides which thereafter can be converted to vitreous fiber and shot. Industrial waste materials suitable for use in the present invention include metal-containing waste products, particularly inorganic hazardous waste materials. The present process accomplishes total recycling in such a manner that the entire industrial waste material is consumed and converted to useful products.
