  • Mine remediation case study

    Bartow, Florida GeoView, Inc. performed a geophysical investigation across a 200 acre site in Polk County, Florida. It had been reported that clay slimes from former mining operations had been deposited on the site. The purpose of the investigation was to help determine the horizontal and vertical extent of the clay slimes. Due to the large size of the site and limited budget, the ...

  • 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 ...

  • Remediation of Abandoned Coal Mines Using Coal Combustion Products

    A slurry of mine water and coal combustion fluidized bed ash (FBA) was injected into an abandoned coal mine in Eastern Oklahoma in July 1997. Oil-field technology was used to inject 1.8 Gg (418 tons) of FBA through five wells in 15 hours. Alkaline minerals in the FBA neutralized acidity and imparted alkalinity to the mine water. Thus, this remediation method uses the waste from an industrial ...

  • Dealing with environmental legacy effects: the economic and social benefits of acid mine drainage remediation

    This paper is concerned with developing a practical methodology for prioritising measures to ameliorate the environmental problems associated with the abandonment of mine workings. Although much attention is focused on the pollution associated with on-going industrial production, rather fewer resources are going to develop methodologies for handling the environmental legacy effects of our ...

  • 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 ...

  • Closures of mine a new challenge for Romania

    AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country. In time the economic content of metals diminuend, and the ore mines become non profitable. Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...


  • Sonic making inroads on PCB remediation?

    The Sydney Tar Ponds of Nova Scotia are the result of a century of coal mining and steelmaking, which left behind 900,000 tonnes of chemical waste. About 5 per cent or 45,000 tonnes of this waste is contaminated with high levels of PCBs. Two years ago a federal-provincial plan was announced to clean up the Tar Ponds over 10 years at a cost of $400 million, and this led to the creation of the ...


  • Remediation of DNT drum disposal area.

    In 1991, an abandoned drum disposal area was discovered in a small ravine known as the Wash 3 tributary at the Apache Powder Superfund Site near Benson, Arizona. The 110-gallon steel drums were found to have been used to store 2,4- and 2,6-dinitrotoluene (DNT) that was purchased for experimental formulation of a composite explosive for the mining industry in the 1955 to early 1960's timeframe. ...

  • Open water spill at Kemess Mine in Canada

    We received a request for SpillRemed (Industrial) from Kemess Mine located in the rocky mountains in Canada. The mine was so inaccessible that it took almost 10 days for the shipment to reach the customer. The company had a diesel spill in the containment berm and as per the standard protocol absorbent booms were placed to recover the spill, but unfortunately the boom absorbed water and sank at ...

  • Position Brief on oil sands mining in Canada

    Background The oil sands (also called tar sands) in Canada are the second largest petroleum deposit in the world after Saudi Arabia and underlie about 140,000 square kilometres of land in northern Alberta, composed of woodlands and wetlands. Wetlands cover roughly half the landscape of the oil sands region and a vast majority of these wetlands are peatlands. Oil sands development has ...

  • How solar is transforming an old mining town

    You hike over the crest of the hill and there it is: 96 sun-tracking solar masts, each with 42 solar modules — 4,032 modules in all — perched on the side of a hill with the beautiful Rocky Mountains in the background. It’s called the SunMine project and it’s all part of the reinvention of Kimberley, B.C., from mining town to a clean tech, tourism town of the ...

  • Optimising the rehabilitation of polluted mine tailings and water by an organic medium passive acid mine drainage treatment in South Africa

    Up to the present polluted Acid Mine Drainage (AMD) also known as Acid Rock Drainage (ARD) from South Africa's gold mines was treated by the precipitation of heavy metals with lime and expensive caustic soda where the residues accumulate in the treated water. This water then is dispersed into wetlands for natural remediation. The environmental damage to soil is irreversible and can sterilise soil ...

  • Electrokinetic remediation study for cadmium contaminated soil

    Cadmium is a non-essential heavy metal pollutant of the environment resulting from various agricultural, mining and industrial activities and also from the exhaust gases of automobiles (Foy et al., 1978). Due to its high toxicity and greater solubility in water and its wide distributions in aquatic ecosystem, it has been considered as extremely significant pollutant (Lockwood, 1976). Great ...

  • Remediation of petrol-contaminated sediments in a tropical environment

    Conventional and experimental methods were studied for the remediation of petroleum contaminated sediments from a dam previously used to collect acid run-off from a sulfur mine. The man-made lake had been neutralized, but bentonite rich sediments remained contaminated with very weathered hydrocarbons (sediments with ~50,000–60,000 mg/kg Total Petroleum Hydrocarbons were used in this study). ...

  • In Situ electromagnetic heating for hydrocarbon recovery and environmental remediation

    Introduction Thermal recovery methods, as applied in heavy oil and oil sand deposits, and in environmental remediation, have the common objective of accelerating the hydrocarbon recovery process. Raising the temperature of the host formation reduces the oil and bitumen viscosity, and, in environmental remediation, increases vapour pressure. These effects assist in sweeping the substances ...

  • Anaerobic Bioremediation of Acid Mine Drainage using Emulsified Soybean Oil

    Batch incubation and flow-through column experiments were conducted to evaluate the use of emulsified soybean oil for in situ treatment of acid mine drainage. Addition of soybean oil, soluble substrates, and a microbial inoculum to the batch incubations resulted in complete depletion of SO4, 50% reduction in Fe, and an increase in pH to >6. A one time injection of emulsified soybean oil, lactate, ...
