  • Downstream sulfuric acid plants benefit from WESP technology

    Industrial-grade sulfuric acid, still the most widely used industrial chemical in the world, continues to be sourced primarily (about 70 percent) as a nondiscretionary byproduct from the roasting, smelting, and refining of nonferrous metals. The rest comes from natural gas processing, electric power generation, and spent acid regeneration. These industries are usually heavy emitters of ...

  • 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 ...

  • Mining Metals Solution Treatability

    Integrated Engineers, Inc. conducted a treatability test on water containing metals in solution from a mining company’s analysis labs. Initial pH was below 2, so it was adjusted to 6.5 to 7.5 using caustic. This lowers the solubility of the metals, and helps the Floccin to work better. The Floccin-1105 worked well at a dosage of 2.1 grams/ 1,000 ml of wastewater (treatment dosage of .9 lbs. of ...

  • 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 ...

  • Membrane Bioreactor for Water Mining in New York City

    The Facility The Helena, which opened in late 2005, is an apartment building that offers more than amenities, views, and nice finishes. Behind the $100 million tower’s gleaming glass and metal skin is a serious high-performance building. Its owner and designers say the Helena will annually use 65 percent of the energy and one-third of the potable water of comparable ...

  • Optimising the Rehabilitation of polluted Mine Tailings and Water by SupaZorb

    To date the polluted acid mine drainage (AMD) – the second biggest environmental problem of the world - from South Africa’s gold mines, was characterised and treated by the precipitation of heavy metals with lime and sulphates, by means of iron exchange. The chemical treatment with expensive and toxic caustic soda (Sodium Hydroxide, NaOH) is to lift the pH, in order to reduce the corrosion on ...

  • Wastewater Treatment for the Mining Industry

    Sustainable wastewater technologies minimize mining’s environmental footprint Mining for some minerals, including coal, has been diminishing due to increased financial, social, and environmental pressures, both in the United States and abroad. At the same time, mining for lithium and other metals — used in energy storage for electric cars, and wind and solar generation — is ...

  • 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 ...

  • 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 ...

  • THIOPAQ® technology for the mining and metallurgical industries

    Abstract THIOPAQ® technology, developed and marketed by PAQUES Bio Systems B.V. in Balk, Netherlands, was first applied commercially in 1992 for the treatment of contaminated groundwater at the Budelco zinc refinery in the Netherlands. In its most basic form, a THIOPAQ® system essentially consists of two biological process stages in series: (i) sulfate reduction to sulfide (anaerobic stage), ...

  • 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 ...

  • Treatment of wet peat mining process water with acrotelm peat

    Mechanical dewatering of wet mined peat produced peat mining process water (PMPW) with low pH (5.49) and high total suspended solids (TSS 432 mg L−1), Al (1.39 mg L−1), Fe (4.36 mg L−1), Hg (37.1 ng L−1), MeHg (0.485 ng L−1), Zn (55 μg L−1), total nitrogen (TN 7.92 mg L−1), ...

  • Treatment of iron(II)-rich acid mine water with limestone and oxygen

    The main components of acid mine water are free acid, sulphate, and Fe2+. Limestone is the most cost-effective alkali that can be used for neutralization. The purpose of this investigation was to identify conditions where Fe2+ is removed with limestone and simultaneously oxidized with oxygen to Fe3+, in a polyvinyl chloride pipe under pressure. Gypsum ...

  • Peristaltic Pumps play key role in rectifying the pH balance of mine water

    After decades of uncontrolled industrial (mining) activities, water supply is under serious threat. Studies show that acid water levels in the country's mines are rising at a staggering average rate of 0.59 m/day. The water situation is in fact threatening the population’s survival. At the heart of resolving this problem are the treatment of water and wastewater. This article looks at ...

  • Wastewater treatment for mining camps/oil and gas camps

    Mining and oil and gas camps operating in remote and environmentally sensitive areas become home to large work forces for extended periods of time. Supplying water for domestic use and treating large volumes of sewage and greywater can be a complex and expensive challenge. Improper wastewater treatment can lead to pollution of the surrounding ecosystems. Many jurisdictions have tightened ...

  • Major Wastewater Treatment Breakthrough in the Mining Industry

    Over the past two years, mining research and operations in Ontario have taken off. In fact, you might even say they’ve skyrocketed. This newfound surge can be seen more particularly in the Great North region known as the Ring of Fire, some 240 kilometres west of James Bay and north of Thunder Bay. At the present time, some 40 mining and exploration companies are active at the heart of this ...
