Mine tailing disposal sites: contamination problems
Mining practices and the absence of proper mine land reclamation has led to heavy metal contaminated sites with serious impact on the ecosystems and risk for human health. The origin of the contamination is often associated to mine tailing deposits because they are a source of the acid mine drainage (AMD). These areas are devoid of Previously Producing Patented Gold Mine for Sale in the USA. $1.6 Billion Estimated & Inferred Resources including 80,000 tons in Mill Tailings.

Tailings: Dangerous Wastes or Precious Treasures?
Tailings often contain trace elements such as Zn, Mn, Cu, Mo, V, B, Fe, and P, which are essential for maintaining plant growth and development. The tailings discharged by some dressing plants in Japan Zone 2 was positioned about 5–7 km beyond the highly dense mine tailing area, occupying the western side of Virginia, as well as the south-southwest border of the highly dense mine tailing area. The third zone, Zone 3, did not contain mine tailings or mining activities, but these sites were located approximately 7 km–10 km east of theContamination of groundwater by potential harmful

What are Tailings Society for Mining, Metallurgy
Tailings are a by-product of mining. After ore containing an economically-recoverable commodity is mined from the earth, that commodity is extracted in a processing plant or mill. After the commodity of value is extracted from the ore material, the resultant waste stream is termed “tailings”. Typically, mill tailings range from sand to siltCopper mining, the central axis of Chile’s economic development, produces a large number of tailings, which become a potential environmental risk. This study aims to evaluate the mechanical properties resulting from the making of Portland cement mixtures with tailings as aggregates so that they can be eventually used in paving stones for IJERPH Free Full-Text Making Paving Stones from Copper Mine
