How can metal mining impact the environment? American
Underground mining generally results in relatively small waste rock disposal areas ranging from a few acres in size to tens of acres (0.1 km2). These areas are typically located near the openings of the underground workings. Open pit mining disturbs larger areas than underground mining,

Sea disposal of mining waste could spread as Indonesia weighs adopting the technique for new nickel projects, as Papua New Guinea is doing for a gold mine proposed by Australia's Newcrest Mining. The management of mining waste has drawn attention since two dam disasters in Brazil, and after red mud spilled into Papua New Guinea's Basamuk Bay from Ramu Nickel's operations in August.
Air Cannons Reduce Clogging Downtime at Nickel Mine
The company extracts approximately 2,200 st/pd (2,000 mt/pd) from the underground nickel-copper mine using a bench-and-fill stoping process. Clogging issues were affecting an undersized chute in the Humbolt milling process, which would stop the entire crushing process approximately 3-4 times per shift for as long as an hour, blocking input of material all the way back to the ore storage area.

Top 10 Ways to Make Mines More Environmentally Friendly
Apr 29, 2014Top 10 Ways to Make Mines More Environmentally Friendly. This creative trend of scrap mining, or utilizing ever-reusable resource for other mining initiatives, stems from the recognition of the environmental costs of excessive materials use. Mining exacts a severe and sometimes irreversible toll on public health, water and air quality,
A Pennsylvania Mining Town Moves Beyond Toxic History
The Cinder Bank is what is left of the 33 million tons of slag (rocky waste) left by the New Jersey Zinc Company as a byproduct of their mining operations. According to the U.S. Environmental Protection Agency (EPA), this pile extends for 2.5 miles and is over 100 feet high and 500 to 1000 feet wide.

Nickel production volume in the first half of the year was 9,963 tonnes, exceeding the production volume of the whole year 2016. The primary bioleaching area was taken in full production use in mid-May, when the area was fully stacked with new ore.
management is the key to soil quality. This series of technical notes examines the areas in or around mining waste piles and tailings, industrial areas where lead, nickel, copper, zinc, chromium, and manganese. The most common anionic compounds (elements whose forms in
Health hazards and waste management British Medical
Dec 01, 2003Waste management is now tightly regulated in most developed countries and includes the generation, collection, processing, transport and disposal of waste. In addition the remediation of waste sites is an important issue, both to reduce hazards whilst operational and to prepare the site for a change of use ( e.g. for building).

R 527 At the end of the mine operations phase, plans for management of waste rock and tailings to prevent, control and treat metal leaching and acidic drainage should be re-evaluated and revised as necessary, to ensure that they are consistent with the objectives and plans for mine closure and post closure. This evaluation should consider

Ansel Hubble established gold claims in the upper East Boulder drainage in 1893 and operated a nickel mine in the Hubble Gulch area in 1894. Hubble filed the Morning Star and Pilgrim Lode claims in 1894 near Hubble Gulch. He probably abandoned the site shortly
Economic Valuation of the Post Nickel Mine Reclamation in East Luwu Regency, South Sulawesi . Externality from the activities of nickel mining is the degradation of environment quality and the reclamation of post mining activities. The success of reclamation of the post mining area depends on the policy system that implemented
Biomining is mineral processing with microbes. Biomining is the process of using microorganisms (microbes) to extract metals of economic interest from rock ores or mine waste. Biomining techniques may also be used to clean up sites that have been polluted with metals.

Jul 23, 2018Innovative Incineration Solutions for Greenland's Mining Waste. As more and more mining operations open up the unexplored frontiers of Greenland's rugged landscape, the demand for a safe and effective way to dispose of mining waste is increasing. At Inciner8, we're helping to lead the way in pioneering incineration solutions.
Approximately 99% of the rock extracted in the proposed mine will be waste. When this waste rock interacts with water and air, sulfuric acid and toxic metals will be released. Similar mines throughout America generate hundreds of millions of gallons of acid mine drainage and will require active water treatment for thousands of years to avoid complete destruction of streams and groundwater.
Surface or open pit mining and underground mining are hazardous in all stages of mining. Soil waste dug and tunnelled is left as tailings or spoils, and can expose radioactive rocks, and create metallic dust. These tailings are also subject to erosion by wind and rain.
