01/01/2012 The important issues on disposal of solid wastes from metal mines are to choose the right varieties for the comprehensive utilization of mining waste and to control contamination from waste rocks and tailings. Environment- friendly disposal of solid wastes from mines is the key pathway. This paper summarizes and enumerates some comprehensive utilization methods and proposes new ideas
Despite numerous recycling methods, the majority of mine waste is still stored in facilities or waste sites. The long-term storage of these facilities has become an important topic in modern mine closures. Various regulations have come to pass that require the waste to be stable for years, sometimes centuries. This requires engineers to develop storage methods to withstand catastrophic events ...
01/09/2008 In view of these, it is worthwhile for the industry to consider the option of recycling mine waste. Further, such an effort by the Goan iron ore mining industry will displace the laterite mining, which caters to construction industries requirement in Goa. As a direct consequence of this, the environmental impacts due to primary laterite mining activity would be reduced. This would accord a ...
Waste disposal in underground mines is not a revolutionary concept. "A Dictionary of Mining, Mineral, and Related Terms" (U.S. Bureau of Mines, 1968) actually defines backfill as "Waste sand or rock used to support the roof after removal of ore from stope." But many mines choose not to backfill with waste rock for a variety of technical and economic reasons. Much of the underground void volume ...

Some of the impacts of the mining waste include: Unpleasant visual impact as big piles of waste stand out like sore thumbs. Takes up large areas of land for their storage and disposal and also make the land infertile and useless. Waste disposal by in-pit dumping is considered to be the most economical and environment friendly9 Heavy metal contamination which reduces soil productivity or ...

One such company Schnitzer Steel Industries Inc, founded in 1906 as a one-man scrap metal operation, is now one of the largest recyclers of scrap metal, a leading provider of used and recycled auto parts and a manufacturer of finished steel products.

10/08/2018 Tailings are a type of rock waste from the mining industry. When a mineral product is mined, the valuable portion is usually embedded in a rock matrix called ore.
The processing of black coal in Australia segregates waste in the form of coarse reject and fine tailings. The coarse reject is relatively easy to handle, while the tailings can be problematic. Conventionally, the two waste materials are disposed of separately, the coarse reject in dumps, and the tailings in man-made containments. Aqueous tailings slurry...

21/05/2020 Improper mining waste disposal will lead to air, soil, and water pollution. Different types of mining include landfill mining, coal mining, oil and gas extraction, metal, and non-metal ore mining. In this article, we will look at different types of mining waste and how to manage it effectively. Types of Mine Waste 1. Rock or Solid Mine Waste
1 Waste Disposal Options All mining operations generate waste.1 One of the most widespread management problems in the mining industry relates to the sheer volume and chemical composition of waste material handled. These very high volumes mean that where it is put and how it is managed are critical to determining the impact of mining. 1.1 Initial Considerations Ore bodies are mineral ...

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, and thus has larger visual and physical impacts. As the amount of waste rock in open pit mines is commonly ...

28/03/2018 Waste accounts for 99.9 percent of the processed material in gold production, 99 percent for copper and 60 percent for iron. Sometimes disposing of tailings on land isn’t the preferred option, Vare said.
