  • Equipment CO2 emission in surface coal mining

    The continuous global increases in energy demand and the environmental impact of carbon dioxide (CO2) emission, represent a substantial challenge for the mining industry. This paper presents the results of research work related to determination of surface mining equipment CO2 emission, which is part of a broader industrial project on analysis and control of energy consumption. The project was ...

  • Analyses of trace elements on quartz surfaces in sulfidic mine tailings from Kristineberg (Sweden) a few years after remediation

    Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has been applied to determine the elemental composition of the surface layer, as well as of the first interior layer, of quartz grains from the mine tailings from Kristineberg (northern Sweden) in order to determine concentration gradients between these two layers. The quartz grains were collected from the oxidized and ...

  • Deep sea mining — a dangerous experiment

    Pacific governments should not approve deep-sea mining until more is known about its likely impact, says conservation biologist Mellie Samson Jr. Deep sea mining (DSM) is the new frontier in extractive mining. For the companies involved, as well as the governments that own the mining rights, it offers substantial profits. However DSM is still experimental in nature, with ...

  • Deep sea mining: exploration is inevitable

    Despite concern over adverse impacts, deep marine mineral exploration is set to become a global industry, says geologist Chris Yeats. Global demand for metals continues to grow, fuelled largely by increasing populations and the industrialisation and urbanisation of China and India. To meet this demand, the international ...

  • Wastewater Mining and Reuse: Creating Benign Future Scenarios

    Wastewater mining: In addition to being perhaps the most uninviting combination of words, it sounds like a most unlikely idea. But for almost 30 years, Aqueonics, now headquartered in Greenville, SC, has pioneered such systems, starting in the ’80s, with its first wastewater mining project. For that project, Aqueonics provided an onsite or decentralized treatment system for a developer in ...

  • Coal Mining and Production Industry - Pollution Prevention Guidelines

    Introduction Pollution Prevention Guidelines to provide technical advice and guidance to staff and consultants involved in pollution-related projects. The guidelines represent state-of-the-art thinking on how to reduce pollution emissions from the production process. In many cases, the guidelines provide numerical targets for reducing pollution, as well as maximum ...

  • Common Treatment Technologies for Explosives in Ground Water, Surface Water, and Leachate

    Explosives-contaminated process waste waters can be subdivided into two categories: red water, which comes strictly from the manufacture of TNT, and pink water, which includes any washwater associated with load, assemble, and pack (LAP) operations or with the demilitarization of munitions involving contact with finished explosive. Despite their names, red and pink water cannot be identified by ...

  • Treatment of Acid Mine Effluents Using a Wood- Waste Cover

    At the East Sullivan site, wood wastes covering the abandoned mine tailings impoundment prevent sulfide oxidation by creating an anoxic environment. The addition of coarse ligneous wastes and their high permeability favour infiltration, resulting in a water table rise that maintains most tailings under water saturation and thus provides an additional protection against sulfide oxidation. ...

  • Management of Mining, Quarrying and Ore-Processing Waste in the European Union

    At the request of the Environment Directorate-General of the European Commission, BRGM (Bureau de Recherches Géologiques et Minières) has conducted a study on the management of mining, quarrying and ore-processing waste in the European Union. This project was completed mainly through the use of questionnaire sent to sub- contractors in almost each country of the EU. To assess this information ...

  • Modelling the Long-term Release of Sulphate from Dump Sediments of an Abandoned Open Pit Lignite Mine

    The generation of acid drainage from overburden spoil piles at open-pit lignite mines impacts water quality in large parts of the Lusatian mining area in Germany. The Lohsa Mine was exploited until the early 1990s and is to be flooded by 2005. It will then be used as a reservoir basin for the river Spree. Future acidity and sulphate concentrations in the surface water are of great interest ...

  • VSEP provides crystal clear permeate and recovers precious metals from the mining leachate at 97% recovery

    A unique membrane filtration system, known as V✧SEP (Vibratory Shear Enhanced Process), was developed by New Logic of Emeryville, California. The technology employs vibrational oscillation of an advanced polymeric membrane to improve the throughput and to prevent colloidal fouling of the membrane surface. This new technology provides a innovative and cost effective method of recovering ...

  • Rehabilitation of Mine Tailings by Simultaneous Prevention of Oxidation and Treatment of Acid Effluents Using a Wood-Waste Cover

    At the East Sullivan site, wood wastes covering the abandoned mine tailings impoundment prevent sulfide oxidation by creating an anoxic environment. The addition of coarse ligneous wastes and their high permeability favour infiltration, resulting in a water table rise that maintains most tailings under water saturation and thus provides an additional protection against sulfide oxidation. ...

  • HybridICE® filter: ice separation in freeze desalination of mine waste waters

    Freeze desalination is an alternative method for the treatment of mine waste waters. HybridICE® technology is a freeze desalination process which generates ice slurry in surface scraper heat exchangers that use R404a as the primary refrigerant. Ice separation from the slurry takes place in the HybridICE filter, a cylindrical unit with a centrally mounted filter element. Principally, the ...

  • Acid Mine Drain (AMD) treatment to achieve very low residual heavy metal concentrations

    Abstract Mount Emmons mine wastewater treatment plant currently treats on average around 450,000 gallons per day of acid mine drain (AMD) water collected into several collection ponds. The plant uses standard lime hydroxide precipitation process at pH 10.7 to precipitate heavy metals and remove AMD contaminants with the subsequent flocculation - dissolved air flotation (DAF) and sand ...

  • Sequential extractions on mine tailings samples after and before bioassays: implications on the speciation of metals during microbial re-colonization

    Abstract  Mine tailings may be remediated using metal tolerant microorganisms as they may solve the limiting conditions for healthy development of plants (i.e., low organic mater content and poor physical conditions). The aim of this study was to investigate the consequences of microbial colonization on the chemical speciation of trace metals. Surface samples from the Valenciana mine ...


  • Western Canadian Coal Adopt MP-5

    Western Coal are based in Vancouver, British Columbia, Canada. They currently produce metallurgical coal  from mines located in the northeast of British Columbia, both metallurgical and thermal coals from mines in West Virginia, and anthracite coal from a mine in South Wales (UK).  The coal properties in British Columbia have over 127 million tonnes of reserves and over 230 million ...

  • Relationships between pH, colour and heavy metal concentrations in the Tinto and Odiel rivers (southwest Spain)

    The relationships between pH, colour, Fe, Mn, Cu, Zn, Cd and sulphates in surface water samples collected from the Tinto and Odiel Rivers (southwest Spain) have been studied. These rivers are adversely affected by the inputs of acid and heavy metals due to Acid Mine Drainage (AMD). Samples were collected from both rivers on a monthly sampling basis from 1995 to 2001. The analytical results showed ...
