  • Are mining waste disasters inevitable?

    On 5 November 2015 the dam of an iron ore tailings management facility in Bento Rodrigues, Brazil, suffered a catastrophic failure and flooded the area. The immediate consequences were dire: the accident killed at least 11 people, injured over a dozen more and left more than 500 people homeless. However, this is just the start: the environmental impact of the Bento Rodrigues dam disaster, with ...

  • MRW - Mining the Urban Waste

    An article on 'Mining the Urban Waste' has been published in the December edition of Materials Recycling World (MRW). With metal scarcity soaring up the political agenda, Dr Tim Johnson, Technical Director at Tetronics International, explains why - and how the waste sector can benefit: Until 2003, the prices of an enormous range of metals had remained amazingly constant for decades. It ...

  • Sustainable mining

    It's imperative that natural resource industries adopt a proactive (even aggressive) approach to the disposal and management of their wastes. Operators must challenge themselves to raise the bar in terms of environmental performance not only to meet the expectations of regulators today (and investors and the general public), but in the future, when requirements will no doubt be even more ...

  • Mining, the environment and the treatment of mine effluents

    The environmental impact of mining on the ecosystem, including land, water and air, has become an unavoidable reality. Guidelines and regulations have been promulgated to protect the environment throughout mining activities from start-up to site decommissioning, in particular, the occurrence of acid mine drainage (AMD), due to oxidation of sulfide mineral wastes, has become the major area of ...

  • A Study on the Costs of Improving the Management of Mining Waste

    1. Executive Summary Context, Scope and Priorities 1.1 This is the Final Report of a study into the costs of improving the management of mining waste. It was not carried out in isolation, but in parallel with a consultation process being run by the Directorate General for the Environment of the European Commission (DG ENV) and a technical review process coordinated by the European Integrated ...

  • Eco waste solutions voisey’s bay nickel mine

    The challenge Vale Inco’s wholly-owned subsidiary Voisey's Bay Nickel Company (VBNC) is mining the largest nickel deposit in the world in Newfoundland Canada. During the Construction and Operation Phases of the camp, waste from 250 to 700 people needed to be processed. This waste was largely generated by the kitchen and dining areas. Packaging waste (wood, ...

  • Abandoned Wells and Mines as Underground Storage for Waste Management

    Abstract Albania is a rich country in oil, mineral and water sources as well as a very polluted one in Europe There are a lot of wastes that couldn’t be managed in existing circumstances. At the present many oil and gas fields are in the third or depleted phase of the exploitation, while a lot of mines are abandoned. In this frame the paper presents some considerations to use them as underground ...


  • Electronic Waste: The Rich Resource in the Urban Mine

    Forgetting your mobile phone can be a real pain, playing on your mind during the day. Then as you think you can feel your phone vibrating in your pocket and you come to realise how dependent we are on our gadgets. Electrical equipment has changed our lives completely and we rely on phones, microwaves, TVs, kettles, computers to keep us informed, entertained and even alive. It is hard to imagine ...

  • Comparison of Gas and Water Pycnometry of Coal Mine Wastes

    Coal mine washery wastes comprise two major components whose specific gravities differ markedly. Consequently, their specific gravity is much more variable than that of natural soils and is determined relatively frequently. The specific gravity of coal mine wastes is determined more rapidly and efficiently by gas pycnometry than by water pycnometry. However, the two methods give significantly ...

  • "Don`t waste a drop" - water in mining

    Christopher Gasson explains the complex relationship between the mining industry and global water supply Water has always been important for mining, but suddenly it has become a board-level issue. Shareholders now expect companies to have identified the operational and environmental risks they face as a result of their water usage, and show that they are pursuing strategies to minimise this ...

  • Cleaner Production in the Mining Industry: Mount Isa Mines

    MIM Holdings Limited has implemented a program of innovations which has enabled the company to open a new mine and add new electricity-using activities while cutting total annual electricity use and carbon dioxide emissions. MIM has committed to the Australian Governmentís Greenhouse Challenge. This Federal and State Government sponsored initiative requires companies to reduce emissions of carbon ...

  • Acid mine drainage treatment

    Acid mine/rock drainage is a rampant problem in the world today. The above photo depicts acid drainage at an abandoned mine in the Yukon Territory of northwest Canada. This mine shares a similar history to thousands of other mines throughout the world. It was in operation for six short years in the 1950’s, producing gold ore. Its profitability eventually failed and it was abandoned. In the ...

  • Mining Water Quality Application

    Isaac Plains Coal Mine Isaac Plains is an open cut coal mine, in Northern Queensland, Australia. The Isaac Plains Project operates under an Environmental Authority (EA). One of the environmental monitoring requirements which must be met is monitoring water. These include potable water, mine affected water, natural creek flows, water releases, groundwater and the receiving environment. The ...

  • Bioremediation of copper mine waste: a case study from Mosaboni copper mines, Eastern India

    The concentrations of different forms of heavy metals were determined in a mine dump rich in chalcopyrite, pyrite, pyrrhotite, molybdenite and other sulphide minerals. A pilot scale study was conducted by transporting 14 tons of copper tailings from Mosaboni mines and exposed to natural weathering conditions and normal plant colonisation for one year. After one year different forms of metals were ...

  • Nano-structured calcium silicate as sorbent in a study of artificial mining waste

    Nano-structured calcium silicate can adsorb a wide variety of ionic species. The mechanism of the uptake observed depends on the nature of the species and is selective towards the more insoluble hydroxides for cationic and insoluble calcium compounds for anionic sources. Additionally, waterborne solids can become trapped, with the silicate, acting as a filter. Artificial mining waste samples have ...

  • 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. ...

  • Utilisation of municipal solid waste as an amendment for reclamation of coal mine spoil dump

    Mine spoil dumps generated due to mining activities pose drastic physico-chemical and biological constraints for sustainable vegetation. Thus an eco-friendly and cost-effective Microbe Assisted Phytoremediation (MAP) is adopted for reclamation of coalmine spoil dumps. The results indicate that MAP is also an excellent tool for fast restoration and productivity of wastelands, 95?99% plants ...
