Subsurface Disposal Of Acid Mine Water

Jan 07, 2015 Acid Mine Drainage A Reusable Water Resource. Implementing sustainable and financially viable methods to reuse vast quantities of acid mine water is an area of relatively new, but growing, interest for mining operations. With the advent of highly-optimized treatment technologies, new possibilities for water recycling have emerged that open up ...

What types of mining are most responsible for acid mine

Acid mine drainage is the formation and movement of highly acidic water rich in heavy metals. This acidic water forms through the chemical reaction of surface water rainwater, snowmelt, pond water and shallow subsurface water with rocks that contain sulfur-bearing minerals, resulting in sulfuric acid. Also to know, how does acid mine drainage ...

subsurface mine water flows and prevent contact with atmospheric oxygen. Keeping oxygen out of the water prevents oxidation of metals and armoring of the limestone. The process of limestone dissolution generates alkalinity. The sole purpose of an ALD is to provide alkalinity thereby changing net acid water into net alkaline water. Retaining ...

For the pilot test, mine water is pumped to the washing screens, and the fines slurry is piped to wells that extend to the underground mine workings for disposal by gravity flow. This is essentially a closed system with the fines being deposited in the water filled mine voids, the water supply wells being located far away from the injection wells.

Water-pollution problems caused by mining include acid mine drainage, metal contamination, and increased sediment levels in streams. Sources can include active or abandoned surface and underground mines, processing plants, waste-disposal areas, haulage roads, or tailings ponds.

Mine Drainage an overview ScienceDirect Topics

Problems at the mining stage center around overburden and waste rock disposal and the potential contamination of surface water courses from disposal of mine drainage waters. Waste rock disposal in mined-out areas is used wherever feasible but because the crushed material does not pack as densely as the bedrock from which it was derived, some ...

1 Rock Fractures and Fluid Flow Practical Problems Rock

Acid mine drainage is produced by the interaction of water with sulfur, which is present as pyrite in mine wastes, to form sulfuric acid. Bacteria speed up the process. Acid mine drainage is a significant problem in eastern U.S. coal mining districts and in some western U.S. base metal mines.

Acid Mine Drainage. Acid drainage polluted stream merges with unpolluted stream downstream from Californias Jamestown mine. Acid mine drainage is one of minings most serious threats to water. A mine draining acid can devastate rivers, streams, and aquatic life for hundreds, and under the right conditions, thousands of years.

DNR Reclamation Abandoned Mine Problems

Acid mine drainage is the most severe and well-recognized environmental problem related to coal mining and can impact surface waters, including lakes, ponds, creeks, and even entire watersheds. AMD is water typically with a pH less than 4 that drains from mine workings and from mine spoils, and coal refuse called acid rock drainage.

DNR Reclamation Abandoned Mine Problems

May 17, 2009 If sulphide minerals are present in any of the rocks, there is the potential for acid mine drainage.Generally rock dumps are not sealed at their base, and the risk of acid water incursion into the surface drainage system or subsurface aquifers is very high.Rock dumps are also highly porous to water flow, and therefore increases significantly ...

An apparatus and method for removing contaminating metal ions and sulfate ions from acidic aqueous solution such as waste mine water which features passing the solution between pairs of electrodes, each pair of electrodes impressed with a voltage selected according to specific ion species and then adding chemical agents to raise the pH and form precipitates of the metal and sulfate ions.

Low salinity hydrocarbon water disposal through deep

A subsurface drip irrigation system is being used in Wyomings Powder River Basin that treats high sodium, low salinity, coal bed methane CBM produced water with sulfuric acid and injects it into cropped fields at a depth of 0.92 m. Dissolution of native gypsum releases calcium that combats soil degradation that would otherwise result from high sodium water.
