Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal min Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks .
Sep 04, 2012· Impacts on the environment due to the extraction of iron from haematite does not only start during the extraction of iron from the ore - it starts when the raw materials are being mined and transported The following are problems which arise from these processes: From mining and transporting of raw materials - Air pollution - Noise pollution

Cast iron has already been mentioned above This section deals with the types of iron and steel which are produced as a result of the steel-making process Wrought iron: If all the carbon is removed from the iron to give high purity iron, it is known as wrought iron Wrought iron is quite soft and easily worked and has little structural strength
Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes or fungi These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons It was discovered in the mid 1900s that microorganisms use metals in the cell
