Acid Mine

Mine acid water is acidic water and contains iron and sulfate, which is formed under natural conditions when geological strata containing pyrites are exposed to an oxidizing atmosphere or environment. One of the impacts of the mineralization zone where there is a mining process is the potential for the formation of acid mine drainage, especially in the Cibaliung gold mineralization area and its surroundings, Pandeglang Regency, Banten Province. Acid-forming sulfide minerals include pyrite (FeS2), headquarters (FeS2), picoliters (FexSx), calcocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), chalocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), chalocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), galena (PbS) ) and sphalerite (ZnS). Of all these minerals, pyrite is the most dominant sulfide in acid formation. Alkaline mine water (alkaline mine drainage) is mine water that has an acidity level (pH) of 6 or more, containing alkalinity but still containing dissolved metals that can produce acids. The quality of mine water, acid or alkali, depends on the presence or absence of acid mineral content (sulfides) and alkaline materials in the geological strata. Acid water formation tends to be more intensive in mining areas. This can be prevented by avoiding exposure to sulfide-containing materials in the free air. Acid-forming sulfide minerals include pyrite (FeS2), headquarters (FeS2), picoliters (FexSx), calcocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), chalocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), chalocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), galena (PbS) ) and sphalerite (ZnS). Of all these minerals, pyrite is the most dominant sulfide in acid formation. Formation of potential acidic water also occurs in tailings which are residues/processing residues containing sulfide minerals. The formation of acid mine drainage does not always develop in every sulfide-ore mining. In certain types of ore deposits, there are neutralizing agents which prevent the formation of acid mine drainage.

The Cost

<p>Drainage from mining sites containing sulfur bearing rocks is known as acid mine drainage (AMD). Acid mine drainage water is a serious environmental pollutant that has its effects on plants, animals and microflora of a region. Mine water drainage mainly occurs due to anthropogenic activities like mining that leave the sulfur bearing rocks exposed. This drainage water poses as a potent soil, water and ground water pollutant. Although a lot of remediation measures have been implemented in the past but, none of them have been able to solve the problem completely. This review intends to focus on new emerging and better techniques in the form of phytoremediation and nanoremediation for treatment of acid mine drainage water. Besides, the review also gives more importance to the phytoremediation technique over nanoremediation because of the cost effectiveness and eco-friendly nature of the first and the nascent status of the latter. A hypothetical model discussing the use of hyperaccumulator plants in remediation of acid mine water has been proposed. The model also proposes natural induction of the phytoremedial ability of the plants involved in the remediation process. The proposed model assisted by inputs from further research, may be helpful in proper treatment of acid mine drainage water in the near future.</p>
