Index / Mining & Minerals - Evaluations / Wastes and Environmental Issues

Marc Bubel reports that in collaboration with Freeport-McMoRan, Schlumberger Water Services developed, tested, and implemented a new generation high-performance mine dewatering well system, combining mine hydrogeology and dewatering expertise with oil-and-gas-based directional well drilling, placement, and construction technology.

An initial well was constructed on a proof-of-concept basis in the Garfield open pit, then a second added after a successful period of pilot testing of the first. The wells have produced significantly more water than older generation vertical in-pit wells.... More →

Teresa Matich reports that Pacific Wildcat Resources reported on November 13 that its Muiane tantalum mine in Mozambique has been destroyed by local rioters. Security staff on site have been injured and from first reports the site camp and equipment have been destroyed by fire, the company said, adding that police were not allowing access to the mine site as it was still being occupied by those responsible.

According to Reuters, the violence began when an illegal miner was shot dead earlier in the month. Mozambican newspaper O Pais states that armed men who blamed the company for th... More →

Yalley and Bansah (2015) report that small-scale mining of precious minerals has contributed immensely to the socio-economic growth of Ghana. The sector provides employment for thousands of people, mostly indigenes of the communities in which they operate, and thereby stemming rural-urban migration. The small-scale mining sector in Ghana also provides raw materials for locally based mineral industries and contributes to foreign exchange earnings. The mining is done with various methods... the Anomabo method, the Chisel and Hammer method, Underground Ghetto method, the Dig-and-Wash method, the... More →

Authored jointly by GWP Consultants LLP and David Jarvis Associates Ltd.,the Handbook is about the design of new quarries, quarry extensions or revised quarry working schemes. The primary objectives of good quarry design are the safe, efficient and profitable extraction of the maximum usable material from the available land while causing the minimum environmental disturbance and resulting in beneficial final restoration and land-uses. The Handbook sets out to provide a source of reference and guidance to those involved in designing and operating quarries. In particular, it should assist them i... More →

On August 5, 2015, EPA was conducting an investigation of the Gold King Mine near Silverton, Colorado, to assess the on-going water releases from the mine, treat mine water, and assess the feasibility of further mine remediation. While excavating above the old adit, pressurized water began leaking above the mine tunnel, spilling about three million gallons of water stored behind the collapsed material into Cement Creek, a tributary of the Animas River.

EPA is working closely with first responders and local and state officials to ensure the safety of citizens to water contaminated by... More →

Kristie Batten reports that two dams at the BHP Billiton and Vale-owned Samarco mine collapsed on November 5, 2015 killing 13 people, with another six still missing, and leaving more than 600 people homeless.

ICMM CEO Tom Butler expressed his profound sadness for the tragic loss of life that resulted from the recent Samarco tailings dam collapse in Brazil, and extended his deepest sympathies to all those affected by the disaster.

In recent weeks, Butler has been consulting with member companies to determine how best to respond as an organization with a commitment to lead... More →

Xiuwu Zhang, et al., report that mining and smelting are important economic activities. However, mining-related industries are also some of the largest sources of environmental pollution from heavy metals. China is one of the largest producers and consumers of lead and zinc in the world. A large amount of lead, zinc, and related elements, such as cadmium, have been released into the environment due to mineral processing activities and have impacted water resources, soils, vegetables, and crops. In some areas, this pollution is hazardous to human health.This article reviews studies published in... More →

Pepper, et al., opine that the Australian mining industries approach to life-of-mine planning has improved considerably in recent decades. It now needs to be matched by, and embedded in, mining governance systems that utilize a comprehensive whole-of-mine-life approach within a isolation.

The need for a more comprehensive approach is supported by the many mining legacies, from historic, recent and some operating mine sites around Australia. There are sites that are leaving enduring environmental, community and public health impacts that are yet to be accurately assessed. While a nu... More →

Seong-Rin Lim, et al., report that light-emitting diodes (LEDs) are advertised as environmentally friendly because they are energy efficient and mercury-free. This study aimed to determine if LEDs engender other forms of environmental and human health impacts, and to characterize variation across different LEDs based on color and intensity.

The objectives are as follows -

(i) to use standardized leachability tests to examine whether LEDs are to be categorized as hazardous waste under existing U.S. federal and California state regulations; and

(ii) to use mat... More →

Mark Willacy reports that the rehabilitation of abandoned mines could create thousands of jobs in areas hit hard by the resources downturn, according to a new report. Queensland alone has more than 15,000 abandoned mines, including 300 classified as mega, large or medium size. A report on these mines by the environmental group Lock the Gate Alliance is recommending the introduction of an independent authority to rehabilitate the sites.

It proposes funding the remediation with a modest industry levy or from the interest on a new cash bond deposit system. The report said the extra mon... More →

P. Eger, P. Jones and D. Green report that the Soudan Mine was Minnesota first iron mine, operating from 1882 to 1962. The mine was donated to the State of Minnesota in 1963 and became a state park in 1965. The mine discharge contains elevated copper and cobalt concentrations and has been treated with an ion-exchange-resin-based system since 2009.

The system includes flow equalization tanks, bag and cartridge filters, a carbon tank and two commercial ion exchange tanks. Although effective, the system high cost, inefficient removal of suspended material and substantial maintenance h... More →

Thomas Hillig, proponent of renewables, opines that significant carbon charges would speed up solar-diesel and wind-diesel hybrid projects at mines and might boost storage applications ...but at what cost and reliability?

Until very recently, there was little activity among mining companies regarding renewable energy. A recent report from CDP, formerly known as the Carbon Disclosure Project, came to the conclusion that the biggest miners are unprepared for the transition to a low-carbon economy. Nine out of the 11 analyzed large mining companies oppose new climate regulation. Only t... More →
