Abstract. Field experiment was conducted on mine spoil dump on an area of 10 ha, to restore the fertility and productivity of the coal mine spoil dump using integrated biotechnological approach. The approach involves use of effluent treatment plant sludge (ETP sludge), as an organic amendment, biofertilizers and mycorrihzal fungi along with ...

Environment and Climate Change Canada (ECCC) is developing Coal Mining Effluent Regulations under the Fisheries Act. These Regulations will reduce the risks to fish and fish habitat by limiting levels of harmful substances in coal mining effluent. Once in place, the regulations will apply to the 28 existing coal mines in Canada and to all ...
the existing mine and for the expansion is not practical, particularly where treatment facilities have been designed to meet effluent limits at an established Environmental Compliance Point (ECP). Meeting separate limits could be challenging where characteristics from legacy mining remain influencers of effluent discharge for an expansion area.
Mar 01, 2008 Coal is the major fuel used for generating electricity world wide while the process of coal mining involves the discharge of huge amount of effluent into the surface water. Effluent from coal mine contains high load of TSS, TDS, calcium carbonate and heavy metals hence contaminates the aquatic regime ( Dhar et al., 1986 ).

Aug 01, 2021 The coal mining industries generate a considerable volume of pyrite-rich tailings (FeS 2).However, pyrite waste is potentially reusable. Therefore, this study aimed to evaluate possible ways of waste and effluent valorization that are generated during the processing of coal mining pyrite (R1).
2020 Planning Highlights In 201415, through the Effluent Management Sub-Program, the Department will Continue work to expand the Metal Mining Effluent Regulations to include diamond and coal mines through multi-stakeholder consultations to seek input on proposed changes to the regulations.

TREATMENT OF MINE WATER The mining of coal in the Eastern and Midwestern United States can result in drainage that is contaminated with high concentrations of dissolved iron, manganese, aluminum, and sulfate. At sites mined since May 4, 1984, drainage chemistry must meet strict effluent quality criteria (table 1).
In this study, coal mine drainage sludge (CMDS) impregnated polyurethane granular composite media (PUCMDS) was prepared and used to remove arsenic and other heavy metals in a metallic mine effluent. PUCMDS was used in rapid small-scale column tests to assess the effectiveness and suitability in the application of metallic mine water treatment.
Jan 01, 1992 The Highvale Mine is Canadas largest surface coal mine with annual production of 12 million tons. One and half billion gallons of mine water effluent is produced annually from surface runoff and groundwater that enters four different mine pits. This water is contaminated by suspended solids which ...
SUBCHAPTER E SURFACE COAL MINING, PREPARATION AND RECLAMATION ACTIVITIES 321.71 - 321.81 Effective December 10, 1998 321.71. Introduction and Purpose. The purpose of this subchapter is to promulgate a set of minimum effluent quality standards applicable to point source discharges from any surface coal mining, preparation and
Sep 24, 2016 Present study gives a brief account of water pollution resulted due to coal mining effluent and removal of heavy metals from coal mining effluent. Among the different technologies used for the treatment of heavy metals, phytoremediation is one of the most important one which treats the metals with help of green plants.
Veolia Water Technologies partners with exploration, engineering, and mining companies to solve their mine water challenges, from production of potable water or desalinated water in remote locations to process water and mining wastewater treatment solutions for all types of hard and soft rock mining sites including solution mining.

Effluent Treatment Plant. Effluent Treatment Plant or ETP is one type of waste water treatment method which is particularly designed to purify industrial waste water for its reuse and its aim is to release safe water to environment from the harmful effect caused by the effluent. Industrial effluents contain various materials, depending on the industry.
