South Africa acts on acid mine drainage

2011/2/25Acid mine drainage (AMD) occurs when old mine shafts and tunnels fill up, leading to underground water oxidising with the sulphide mineral iron pyrite, otherwise known as "fool's gold". The acid water is believed to be currently about 600m below surface of Johannesburg and surrounding areas, but is rising at an estimated rate of between 0.6 and 0.9 metres a day. Get price

Acid mine drainage

Acid drainage (AD) or acid rock drainage (ARD) is the flow of acidic water from a source. Where that source is a mine then the phenomenon is referred to as acid mine drainage. AMD is often associated with abandoned mine workings where mining has progressed below the water table and pumping has been discontinued. Get price

Utilization Of South African Fly Ash To Treat Acid Coal Mine Drainage

South African (SA) coal mining creates huge volumes of sulphate-rich, pollutant-laden acid mine drainage (AMD). SA law requires costly treatment before AMD discharge. This source of AMD typically has a pH of about 2 and a TDS in the order of 4000-5000 mg/l. Get price

Assessing the sustainability of acid mine drainage (AMD)

2018/9/1The environmental sustainability of acid mine drainage (AMD) treatment at semi-industrial scale is examined by means of the life cycle assessment (LCA) methodology. An integrated process which includes magnesite, lime, soda ash and CO 2 bubbling treatment was employed to effectively treat, at semi-industrial scale, AMD originating from a coal mine in South Africa.

The Regulation of Acid Mine Drainage in South Africa:

Abstract Acid mine drainage (AMD) is arguably one of the most serious environmental concerns in South Africa. AMD is a legacy left behind by abandoned, derelict and defunct mines, and is a continuing by-product of existing mining activities. In addition to its Get price

A Case Study of Stakeholder Perceptions of the History,

In South Africa, acid mine drainage (AMD) is a perennial issue that may have a serious impact on sustainability of ecosystems and the quality of water in the country. AMD has resulted in controversial debates in this country where the ownership of mines has traditionally been characterized by policies of the apartheid era that downplayed community participation in environmental decision making.

Using Wetlands for the Control of Acid Mine Drainage

Metal Removal Processes of Wetlands A wetland environment can remove metals from influent waters in a variety of ways. As chemical oxidation takes place, oxides and hydroxides of iron can be expected to precipitate from surface flow, resulting in the characteristic yellow sediment in mine drainage known as "yellow boy". These precipitates coat the surfaces of the bottom or settle as a Get price
