The mining of rare earth metals, used in everything from smart phones to wind turbines, has long been dominated by China. But as mining of these key elements spreads to countries like Malaysia and Brazil, scientists warn of the dangers of the toxic and radioactive waste generated by the mines and processing plants.
Mining also causes water pollution which includes metal contamination, increased sediment levels in streams, and acid mine drainage. Pollutants released from processing plants, tailing ponds, underground mines, waste-disposal areas, active or abandoned surface or haulage roads, etc., act as the top sources of water pollution.
Ans: The heap leaching is a kind of industrial mining process which is useful for the extraction of precious metals, uranium, copper and several other compounds from their respective ores. This is done with the help of a series of chemical reactions that tend to absorb specific minerals and tend to re-separate them once they undergo a division ...
DISADVANTAGES. ADVANTAGES *que insprational music* We are running out of high grade copper mines, they are disappearing,which means we will have to go back to, traditional mining and phytomining, which sadly, produces lower quality metal.
Mining gives people a portion of the resources needed for modern civilization, but it can also lead to environmental harm. While some are in favor of mining due to the resources it produces and the jobs it provides in the U.S., some are opposed to mining based on opposition to destructive mining practices and environmental concerns.

Advantages: Bronze is an alloy consisting mainly of copper but the addition of other metals (usually tin) produces an alloy much harder than plain copper. Bronze resists corrosion and metal fatigue better, and conducts heat and electricity, better than most steels. Disadvantages: Bronzes are generally softer, weaker and more expensive than steel.

advantages and disadvantage of mining Advantages and disadvantages of open pit mining Advantages and disadvantages of open pit mining. Open pit mining is profitable when the deposit is not very deep or when the terrain is sandy or deli e so that underground mining is not possible.
Mining involves the extraction of valuable minerals from the earth surface. Mining can either be surface mining or sub-surface (underground) mining. Mining not only beneficial to the surrounding community and public in general, but it can also pose a lot of risks to the surrounding community. Let's look at the pros and cons of mining […]
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
• Deep-sea mining is the process of retrieving mineral deposits from the deep sea – the area of the ocean below 200 m. • Depleting terrestrial deposits and rising demand for metals are stimulating interest in the deep sea, with commercial mining imminent. • The scraping of the sea floor and pollution from mining processes can wipe out entire species – many yet to be discovered.
Asteroid mining is the hypothetical exploitation of materials from asteroids and other minor planets, including near-Earth objects.. Notable asteroid mining challenges include the high cost of spaceflight, unreliable identification of asteroids which are suitable for mining, and the challenges of extracting usable material in a space environment.
It requires various machines for mining and refining raw materials, while recycling has considerably fewer energy costs. Energy is roughly 30% of primary aluminum production costs, while aluminum scrap uses 5% of the energy during production. Besides lower energy costs, scrap metal recycling can be even more efficient than mining .
