Constructed Wetlands for Treating Acid Mine Drainage. By Kathryn Smith. Introduction. The mining industry has felt the burden of both negative environmental criticism and strong governmental regulations. In the past, mineral extraction and processing has been a source of many contaminants entering our water, soil, and air. The Pennsylvania Bureau of Abandoned Mine Reclamation recommends a design of to m (3 to 6 feet) standing water, 45 to 61 cm (18 to 24 inches) compost, and 45 to 61 cm (18 to 24 inches) limestone with drainage pipes, with a retention time of 12 to 15 hours in the limestone (PA DEP, b).

Acid Mine Drainage Prediction compares acid rock drainage factors of waste rock piles and tailings impoundments. In examining this table, it is important to note that diffusion of oxygen into water is slow and, therefore, oxidation of iron sulfide is inhibited until the water level drops, which can occur periodically or seasonally in some cases.

Mine water comprises of AMD, neutral mine drainage, and alkaline scarcity mine drainage. When mine and mine waste drainage have neutral pH, with a high concentration of dissolved metals, they are called neutral (or alkaline) mine drainage (Lottermoser, ).Cited by: 4.
Acid mine drainage is a caustic by-product of hard rock mining that can terminally impair waterways and alter landscapes. It occurs as a result of mining operations when sulfide-bearing rock oxidizes to form sulfuric acid in the presence of atmospheric oxygen and water (precipitation, groundwater, or surface water) , , .Cited by: Bioremediation for Acid Mine Drainage: Organic Solid Waste as Carbon Sources For Sulfate-Reducing Bacteria: A Review Figure 1.

Waste rock piles (WRPs) are commonly remediated with cover systems to limit water and oxygen influx and mitigate the impacts of acid mine drainage (AMD) on the environment. While numerous types of cover systems exist, simple, single-layer soil covers remain an attractive option due to their low cost and simplicity of installation.

Keywords: Acid Mine Drainage, Industrial Waste, Heavy Metals, Remediation Introduction The problems of environmental, economic, social and geotechnical stability associated with abandoned, historical or active mine sites is a very serious and global concern in.
The treatment of acid mine drainage (AMD) and circumneutral mine water (CMW) with South African coal fly ash (FA) provides a low cost and alternative technique for treating mine wastes waters. Environmental impact and remediation of acid mine drainage: Key wordsAcid mine drainage 7 Acid rock (e.g.

Mining residues have been in the environ-mental focus for several decades. Most detailed investigation focussed on the processes generating acid mine drainage (AMD), on the estimation of the worst case scenario.

WHAT ABOUT ACID ROCK DRAINAGE. What is acid rock drainage. Acid rock drainage (ARD) is the natural result of oxidizing or “rusting” of certain types of sulfur-bearing minerals in the presence of water, air and bacteria.
ARD is a very weak form of sulfuric acid. Sulfuric acid. capacity to generate acid mine drainage (AMD), an acidic, sulfate-rich, metals-laden effluent.
The Davis Mine located in northwestern Massachusetts offers a model site to study the processes of natural attenuation of acid mine drainage.
These include physico-chemical processes such as dilution and sorption, geochemical processes such as. iii ABSTRACT This research focuses on the remediation of Acid Mine Drainage (AMD) using metallurgical slags. Slag leach beds are a promising low cost and low maintenance technology for theFile Size: 2MB.
Featuring contributions from leading experts in science and engineering, this book explores the complex biogeochemistry of acid mine drainage, rock drainage, and acid sulfate soils.
It describes how to predict, prevent, and remediate the environmental impact of acid drainage and the oxidation of sulfides, offering the latest sampling and. The formation of acid mine drainage (AMD), a highly acidic and metal-rich solution, is the biggest environmental concern associated with coal and mineral mining.
Once produced, AMD can severely impact the surrounding ecosystem due to its acidity, metal toxicity, sedimentation and other deleterious properties.
Hence, implementations of effective post-mining management practices are Cited by: The global mining industry is dedicated to finding solutions for the challenges that acid rock drainage (ARD) can cause at mine sites.

Acid mine drainage remediation options: a review D. Barrie Johnson*, Kevin B. Hallberg School of Biological Sciences, University of Wales, Bangor LL57 2UW, UK Abstract Acid mine drainage (AMD) causes environmental pollution that affects many countries having historic or current mining Size: KB.An introduction to acid mine drainage.
Iron pyrite, FeS2, also known as 'fool's gold', is the most important source of nearly all water pollution originating from mines and their residue deposits.
When pyrite is exposed to air and water, it oxidises to form sulphuric acid and.Characterization and monitoring of waste rock can help you to understand the week zones that allow meteoric waters to enter and transport mine drainage.
In many situations, such as from metal and coal waste, significant amounts of pyrite will cause the waste to go acidic, which further enhances the transport of heavy metals into the.
