Discharges from mining operations are in some ways dissimilar to other types of industrial facilities. Mining facilities are often in remote locations and may operate only seasonally or intermittently, yet need year-round controls because signiicant materials remain exposed to precipitation when reclamation is not completed.

considered acceptable. The decant solutions from the waste retention system, where excess water is present, are treated in a similar manner. The seepage solutions change in character with time, especially in aged sulphide-bearing tailings with the consequent production of acid. By adequate engineering of the waste retention system, seepage is ...

Eng. Geol., 25: 17--31. Mining and quarrying wastes pose problems of environmental pollution. To prevent this, uses must be found for these wastes. The purpose of this paper is to review the availability, distribution and uses of wastes from most mining countries of the world. Some of the uses identified for the waste materials are as …

For years, the solution has been to leave these waste coal piles as-is or cover them up with a couple feet of dirt and grass, which isn't a real solution at all. Dirt cover is a leaky, temporary patch and an excuse to pass the ongoing pollution to future generations. Sealed landfills would cost billions of dollars and would not stop ...

The final form of waste can be detrimental to the feasibility of reuse and recycling because it dictates the cost of further processing. Mining and mineral-processing wastes consist of rocks, soils, oil sands, and loose sediments. The mineralogical and chemical characterizations of mining wastes are useful in forecasting geotechnical …

There are many causes of mining pollution. Some of them include the following: 1. Technological Advancement. Technological advancement has a serious role to play in mining pollution. Before the advent of technology, miners had to resort to conventional methods of extracting mined materials from the ore, and these methods had little to no …

3. Processing Chemicals Pollution. This kind of pollution occurs when chemical agents (such as cyanide or sulphuric acid used by mining companies to separate the target mineral from the ore) spill, leak, or leach from the mine site into nearby water bodies. These chemicals can be highly toxic to humans and wildlife. 4.

First, to access the actual seams or veins of ore, the top layers of rock or overburden must be removed. Once the overburden has been removed, the seams can be extracted. When extracting the seams, there is additional waste rock that must be separated from the ore. This additional waste rock is called gangue.
