Mining waste Environment European Commission

However, other fractions, in particular those generated by the non-ferrous metal mining industry, may contain large quantities of dangerous substances, such as heavy metals. Through the extraction and subsequent mineral processing, metals and metal compounds tend to become chemically more available, which can result in the generation of acid or alkaline drainage.

froth flotation mining wastes

The mining and processing of mineral ores results in the production of large quantities of residual wastes that are for the most part earth- or rock-like in nature. It is estimated that the mining and processing of mineral ores generate approximately 1.6 billion metric tons (1.8 billion tons) of mineral processing waste each year in the United States.
