The liquid waste is known as ,acid, drainage (AD) or ,acid mine, drainage (AMD) or also called ,acid, rock drainage (ARD). ,Acid, drainage has high acidity, turbidity, low pH content, high contents of dissolved ,heavy, metals [1-3], and iron [4]. All coal and minerals mining operation produced much toxic waste. This is harmful to the air,

The acidity of the water will then rise as increasing amounts of ,metal, and sulfates contaminate the water. This process creates what’s known as mining-influenced water (MIW), which is defined as any water that’s been chemically affected by mining or mineral processing. The biggest issues with mining-influenced water include: ,Acid mine, drainage

The ,acid mine, drainage system generally is losing zinc rather than removing this ,metal, (Ceffluent > Cinfluent). The neutral ,mine, drainage system is performing as expected. Presumably, the mix of metals in the synthetic ,acid mine, drainage at pH 3.5 prevents the ,removal, of zinc. The plants are, however, growing well in this wetland. Figure 4.

Abstract. Secondary treatment of ,acid mine, drainage (AMD) from a copper ,mine, in China which has very low-concentration ,heavy metal, ions and high conductivity (2,800 μ s/cm), was attributed to the high concentration of dissolved monovalent and divalent ions. Commercially available polyamide ultra-low pressure reverse osmosis (ULPRO) and ...
