Review of wastewater discharges from coal mines, including a coal industry profile, mine drainage characteristics, treatment technologies and costs. The report was prepared in consideration of possible revisions to existing Effluent Guidelines regulations at 40 CFR Part 434.
Since 2009, VINACOMIN has constructed 29 mine water treatment stations. The management of mine water in coal mines in Quang Ninh coal basin is .
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).
Mining Industry Wastewater Treatment and Metals Recovery As mining sites continue to expand into remote locations, developers are faced with the challenge of minimizing the impact of large runoff streams and metals-laden wastewater on the local environment. To address these challenges, Ecologix provides a complete range of integrated water and wastewater treatment .
are not untypical for mine wastewater/drainage applications, especially in coal mining or tailing effluents. Accordingly, the system needs to be flexible enough to cope with these varying conditions while consistently meeting defined effluent characteristics in the membrane permeate.
Wastewater Neutralisation. Mining and some other industrial waste streams contain high concentrations of metals and sulphate. Elevated sulphate concentrations are normally associated with water from coal mining due to bacterial and chemical oxidation of pyrite (FeS), resulting in Acid Mine Drainage (AMD).
Dec 22, 2015· Treatment equipment available for mining wastewater. The mining industry incorporates a number of disciplines and processes that result in different types of mining wastewater, which require a variety of treatments to ensure environmentally friendly practices.

passive treatment systems are generally measured in their land use requirements. Passive treatment systems use con- taminant removal processes that are slower than that of conventional treatment and thus require longer retention times and larger areas to achieve similar results. The goal of passive mine drainage treatment systems

Tailings are also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terra-cone (terrikon). Examples Sulfide minerals. The effluent from the tailings from the mining of sulfidic minerals has been described as "the largest environmental liability of the mining industry".
