UG-Mat Mineral Processing Wastes Recycled Materials

Mineral processing wastes are referred to in the Resource Conservation and Recovery Act (RCRA) as wastes that are generated during the extraction and beneficiation of ores and minerals. These wastes can be subdivided into a number of categories: waste

Mineral processing operations generally follow beneficiation and include techniques that often change the chemical composition of the ore or mineral, such as smelting, electrolytic refining, and acid attack or digestion. Regulation affecting mineral processing wastes was developed through a long process covering the period from 1980 to 1991.

These wastes and the facilities and commodity sectors that generate them may be affected by the establishment of Land Disposal Restrictions for mineral processing wastes. Through a series of rulemakings EPA has established and applied criteria to determine which mineral processing wastes are no longer exempt from Subtitle C regulation.

EPA Identification and Description of Mineral Processing

These wastes are termed "newly identified" mineral processing wastes. Any newly identified mineral processing waste that exhibits one or more of the four characteristics of a hazardous waste if disposed on the land must be made subject to the Land Disposal Restrictions (LDRs).

The Challenges of Reusing Mining and Mineral-Processing Wastes

Aug 10, 2012 Mining and mineral-processing wastes are one of the world’s largest chronic waste concerns. Their reuse should be included in future sustainable development plans, but the potential impacts on a number of environmental processes are highly variable and must be thoroughly assessed. The chemical composition and geotechnical properties of the source rock determine which uses are
