  • Influence of Copper Mine on Surface Water Quality

    Aras water basin is located in northwest of Iran. Sungun mine which is the largest open-cast copper mine of Iran is located in this region and is in the primary stages of extraction. The influence of mining activity on the quality of regional surface water has been taken in to consideration in this study. Accordingly, sampling was done from 5 local streams in the study area. In order to consider ...

  • 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 ...

They serve the web coating, printing, packaging and other industrial process markets. The Process The site is a coal mine that has been closed for a number of years, ostensibly because most or all of the ...

  • Groundwater and surface water data management at Rosebery Mine, Tasmania - Case Study

    Efficient management of the large monitoring data set is paramount given licence conditions imposed on the mine. Confidence in the data accuracy is crucial in forming the basis for interpretation and subsequent operational decisions. MMG has adopted an Environmental Data Management System (EDMS) comprising the following ‘off-the-shelf’ components produced and supplied by Earth Science ...

  • Mercury contamination of surface water and fish in a gold mining region (Cuyuni river basin, Venezuela)

    In the Cuyuni river basin (Venezuela), artisanal gold mining has caused significant mercury pollution due to extensive use of Hg in Au amalgamation processes. High Hg concentrations up to 4.60 ?g/l were recorded in surface water samples (rivers, streams, mining ponds, springs), which are three orders of magnitude higher than normal worldwide background values (0.003?0.005 ?g/l). Furthermore, Hg ...

  • Impact of using paper mill sludge for surface-mine reclamation on runoff water quality and plant growth

    Paper mills generate large amounts of solid waste consisting of fibrous cellulose, clay, and lime. Paper mill sludge (PMS) can improve reclamation of surface-coal mines where low pH and organic-carbon levels in the spoil cover material can inhibit revegetation. When applied at high rates, however, PMS may adversely impact the quality of surface runoff. Therefore, we applied PMS at 0, 224, and 672 ...

  • 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: 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 ...

  • 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 ...

  • Mining Related Sediment Impacts: Causes, Significance and Solutions1

    The ProblemAs with many production activities related to the use of natural resources, initial legacies in the form of negative impactsare often characterized by acute pollution of surface waters. In the case of the mining industry, long after the originalmining-related activity ceases, residues such as tailings, spoil piles, sediments in settling ponds or sediments reaching natural ...


  • 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 ...

  • 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 ...

  • 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 ...

  • Visualisation of the characteristics of mining subsidence with the consideration of topography: a case study in China

    The existing three-dimensional visualisation of mining subsidence cannot fully convey the original landscape in the mining area. By using GIS and coupling the predicted result of subsidence in different mining stages with the original elevation data, a dynamic visualisation of mining process is approached, which could reflect geomorphologic features clearly. Furthermore, it visually shows the ...

  • 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 ...

  • Cut-Off Wall - Abandoned Mine Tailings Pond - Case Study

    Problem At an abandoned mine in the Yukon Territory, mining for both Gold and Zinc took place until the mid 1950's, with the processing of the ore taking place on the banks of an adjacent lake. Processing methods resulted in the creation of a large mine tailings pond that had high concentrations of iron, arsenic, zinc and lead. Spring runoff and summer rainfall then infiltrated through ...

  • 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. ...

  • Mine Dewatering - The real value of the pumps selected is in the support that comes with them

    Reliable Equipment Depends on Strong Dealer Support When referring to the mining industry, the use of a specialized pumping company that not only supplies equipment, but also understands and provides the support required can play an integral component to the success of a project. This is especially true when working in remote northern areas where down time, has serious schedule and cost ...
