Mining
Mining for coal is something that is widely known, but did you know that diamonds, uranium, copper, and other non-renewable natural resources are also mined? There are two types of mining; surface and subsurface. Questions about the methods and types of mining, what ores are mined, and related questions should be asked in this category.

How mining operation cause the destruction of forest?
Mining operations in forest areas have also contributed to the destruction of forests.Mining activities cause soil erosion,while mine wastes and tailings pollute bodies of water.
How does mining affect air pollution?
Mining causes dust and particles to get into the air. This will add to air pollution. In a coal mine emissions of methane that is helping to mine the coal is also a contributing factor to pollution.
What effect does mining have on the environment?
- destroys forest and wetlands.
- It may mean that you have to cut down lots of trees just to get to the spot that has all the gold or iron ore.
- Many mine require tailings dams to prevent waste being washed into the rivers. Unethical miners can dispense with the dams, to save costs, resulting in massive pollution downstream. In other cases, the tailings dam can overflow, and even breach, during periods of heavy rain.
- Underground coal mining can require the removal of almost an entire layer of material deep under the surface. When the timber supports collapse, this can lead to subsidence. The subsidence can mean economic loss to people above or damage to natural areas. It can even cause cracks in river beds, leading to loss of river flow.
- Some mining involves the inadvertent dispersal of heavy metals, such as lead, into the atmosphere. This can have serious health effects, including mental retardation in children.
- Asbestos mining causes the dispersal of asbestos into the environment. This will cause deaths among local residents and workers, often several decades later. Fortunately, the mining and use of asbestos are banned in most parts of the world.
There is no reason for a blanket ban on mining. However, the environmental impact of each proposed mine should be analyzed before permission to proceed is granted. Mining operators must be aware of the potential impacts of their operations and ensure minimum risk to the environment.The holes also spread a big germ to many parts of the world which soon gets the world polluted
How does mining fluorite impact the environment?
The effect of mining quartz is it make the world smell more. If there are still quartz mining going on, monitor lizards will extinct from the world.
Which ore is tin extracted from?
Tin is primarily extracted from the mineral cassiterite, which is a form of tin oxide. Cassiterite is typically found in veins and alluvial deposits in regions rich in tin ores such as China, Indonesia, and Bolivia.
Which state mines the most iron ore?
Minnesota. On the Cuyuna, Vermillion, Gunflint, and Mesabi ranges. This I know because I'm from the area.
What minerals are mined in Michigan?
Some of the key minerals mined in Michigan include iron ore, copper, gypsum, salt, and sand and gravel. Iron ore is particularly abundant in the upper peninsula of Michigan, while copper mining has historically been important in the Keweenaw Peninsula.
What is the equivalent BS steel of astm a36 steel?
BSEN 10025-3GRS420N give me the material composition number
Does salt come from the bottom of the ocean?
Salt's origins are in the rocks on land. As rocks weather and erode, finding their way to the seas and oceans through streams and rivers, minerals such as salts are dissolved in the water and do not evaporate causing the salinity of seawater to increase over time. The vast majority of salt produced today for human use is mined from seas and lakes which evaporated long ago, leaving vast quantities of chemical sedimentary rock known as rock salt.
Where is the deepest mine in Canada?
The Enterprise mine, a copper ore mine located at Mt Isa Mines, is currently Australia's deepest mine. Its shaft is 1,900m deep.
Open cast mining is mines that are dug on hilly areas. It is quick easy way of providing coal but it damages the wildlife and can be quite dangerous. The way open cast mining is carried out is that they stay on the same ground level when digging. This is done by moving the dug out soil along so slowly more area has been dug out. This will continue until all the coal has been removed and then the mine will be filled up again and left to grow naturally.
Yes it it used today!!! For mining and demolishing old buildings making towns, paths, but mostly for MINING!!!!!
Iron, Fe, is mined from the ground it is extremely reactive with oxygen and can burn at high temperatures.
Humans rely on iron or its alloys, steel and stainless steel, to make durable strong objects. Examples - bridges, car bodies, metal furniture, building supporting beams, engines, weapons. The list would be very long.
The iron is protected from oxygen by paint, grease, plastic coating, metal coating or zinc coating.
It's not. it is chosen. just like you. you are the new chosen one. the matrix has you neo
Pyrite is used to make jewelry, semiconductors, and cathodes for lithium ion batteries. It has been suggested as material for photovoltaic solar panels, and was used in radios prior to the vacuum tube (it is still used in crystal radios as a mineral detector). In the past, it was used to manufacture iron sulfate and sufuric acid, and is now used commercially to produce sulfure dioxide, commonly used in the paper industry.
What is mining Spanning Tree algorithm?
It prevents loops in a switched network with redundant paths.
The color of a mineral's streak depends on the color of the mineral?
The color of a mineral's streak is the color of the powdered mineral. It may be different from the color of the mineral itself due to impurities or the crystal structure affecting light reflection. This property is useful in mineral identification.
What is the difference between open-pit mining and underground mining?
I was searching for an answer for my science homework, when I stumbled upon this answer. This was very incorrect, and I would like to fix it for you. Here is the correct answer: Open Pit Mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.Hope this helps!

What is atypical day like for a paleontologist?
On a typical day, a seismologist is usually studying the instruments that monitor shocks and any seismic activity on the earth. Seismologists carry out a lot of graph reading and record keeping.
How deep in the ground do you have to dig to find metals?
Depending on what you want to mine dictates how deep you have to mine.
Take coal for an example. - Coal comes in layers the coal at the top is cheap and the coal lower down is more mature and is worth more. Therefore if you want good coal you will have to dig a long way down.Some underground mines are well over one mile deep. 120 metres
What are some advantages and disadvantages of mining engineering?
disadvantages of mining is that the chemicals used to extract the minerals will go down lakes which well put a big impact on the environment
UPDATE
This answer needs a slight correction. Chemicals are NOT used to extract minerals during mining in the United States. In some instances in South America, chemicals are used to "cluster" ores together, but this practice is not used in the United States. "Pollution of streams" that occurs in the United States is usually from the natural acidity of the geologic formations. Mining companies in the United States are required by federal law to take steps to decrease the drainage of acidic strata, so water pollution is not as prevalent as believed.
Why are diamond mines dangerous?
Diamond mines can be dangerous due to factors such as mine collapses, exposure to harmful chemicals, and the potential for accidents involving heavy machinery. Poor ventilation and unstable working conditions also contribute to the risks associated with diamond mining.
Who are the world's largest engineering firms?
There are numerous engineering consulting firms available to help with services. Many of these can be found online, but they can also be found in person. In general, one of the largest companies out there is General Electric, who offers great engineering services and products, available to everyone.
