Environnement minier: résidus de l'industrie minière et alternatives de valorisation

摘要

Waste reprocessing is one way to solve pollution problems related to mining. The purpose of reprocessing, which generally begins with waste collection, is to separate out valuable minerals from highly polluting ones (especially those which generate acid solutions containing concentrations of heavy metals). Reprocessing should not be limited to instances in which it is directly paid for through sales of reprocessed materials. It can also reduce the overall costs of confining wastes and protecting the potentially affected public. These costs are often very high in regions where there has been a significant amount of mining in the past. Any means of reducing the costs of safety measures, or helping pay for them, would therefore be welcome. Public authorities should consider the environmental problems of the industry in their entirety and support solutions that permit the removal of pollutants from mining wastes and the sale of as much of the remainder as possible for profit.
