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.

What are the 4 main mining methods used in the gold rush?
There were more than two mining methods used during the gold rush. Diggers in the gold rush used the following equipment and methods to find gold :
- Panning involved the use of a solid pan. An amount of potentially gold-bearing dirt was placed in the pan with some water, and gently swished and shaken around, a process which would bring the smaller particles of gold to the surface.
- Cradling involved a wooden box loosely resembling a cradle. The cradle was used for sifting through larger amounts of sediment to find gold, and was popular from the early times of the goldrushes. It required at least two men to work. The cradle had a grate and a sieve. The dirt and sediment to be sifted through was emptied onto the grate in the cradle. The cradle was rocked quickly back and forth (in the action of a cradle) while water was poured over the sediment to help work it through. The grate stopped coarser stones from going through, while the fine material was sifted out the other end. The gold would be left behind for easy collection.
- Fossicking was another method which involved picking at rock and stone with sharp tools until gold was located inside, or to pick through mullock heaps left behind by other miners.
- Sieves were also popular. They were like a pan but with a mesh base through which the water would drain, to help separate gold from similar sized particles.
- Windlass was one of the slower methods of mining for gold. Two people were required to operate it, one at the surface and one in the mine shaft. The person in the shaft filled a bucket with potential gold-bearing soil and rocks, and the person on the surface operated the windlass to wind up the bucket. The contents of the bucket were then sorted through, perhaps in a cradle or a pan.
- A poppet head and winch was a larger version of the windlass. Poppet heads stood over deep mining shafts.
- Stamper batteries were large steam-driven machines, which were used to crush the quartz in order to extract gold.

What impact does mining in antarctica have?
Another Answer
There is no mining in Antarctica.
The environment is too extreme, cold and isolated to make mining any kind of a sound financial investment. This is in addition to it being banned under The Antarctic Treaty.
Antarctica is a continent for science shared among nations representing 80% of the earth's population.
_______First Answer_______ well, firstly mining is illegal until 2041 and was banned by the antarctic treaty in 1991.
scientists already know that there is a big hole in the ozone layer that appears every spring, by mining antarctica we are only making the hole bigger
also it will destroy animals habitats such as penguins and seals
breeding will be hard for them. also mining will poison waters and will destroy half of the land, this will kill seals, whales and penguin and fish and others
although we do not have enough resources to last until 2048 so if we mine there we can drive cars in and use computers and other things. there is a large quantity of oil which is needed, although if we let mining people will fight over it, as people are fighting for oil in Iraq
there is also
- Silver
- Gold
- Cobalt
- copper
- Chromium
- Iron
- Molybdenum
- Manganese
- Nickel
- Lead
- Titanium
- Uranium
- Zinc
soon there will probably be another gold rush if we really need gold even though there is not that much
transport to and from antarctica would be very expensive alone and with all the other fees
there will be another depression.
i have more information, if you want i can give more later!
Who is Europe's lead producer of copper?
Russia is the leading producer of copper in Europe, and 7th in the world. However, this also includes Russia's land in Asia, so the country wholly in Europe with the largest copper production is Poland, who is the 10th largest producer in the world.
No, thankfully it is not. Think of Alaska without a tree, shrub, bush, weed, grass, farm crops (without soil nothing could grow). Think of Alaska without the Kodiak Bear, the Moose, Caribou, wolf, Arctic Fox, Arctic Hare, wolverine, bald eagle, ptarmigan. (without flora the fauna could not survive), Think of Alaska without mountains and hills for if they were solid silver they would have been dismantled and sold on the world market until silver had no value at all.
What did people in Montana mine?

What are the Natural resources of Somalia?

What state in the United States produces the most uranium?
Wyoming has the largest uranium ore reserves in the US. The industry was hard-hit in the 1980's. As of 2006, the only active uranium mine in Wyoming in the Smith Ranch-Highland, which is the leading uranium producer in the US.
Is Mining in Antarctica good or bad?
There is no mining in Antarctica. It is forbidden by the Antarctic Treaty.
What type of locomotives were first used on the London underground?
Coal-burning steam locomotives. Originally these were fitted with condensing equipment to recycle the steam (rather than allowing it to escape into the tunnels), but the condensers made the engines very inefficient and they were soon removed. As might be expected, the air quality in the tunnels was not good, even though there were openings in the tunnel roofs at stations and elsewhere.
++++
It was not long before the system was electrified, for the reasons above.

What minerals are mined in China?
China consumes and owns a high portion of all rare metals. Molybdenum is used in 10% of stainless steel and in Nuclear Reactors. China is said to consume over 60%.
Rhodium, titanium, palladium, steel, oil, gold, coal China wants them all.
In 2005, China's top Molybdenum miner produced 24 million pounds, about six percent of the world's total production.
Well, since the major global suppliers of Molybdenum) replenish only 88% of the molybdenum consumed in Y 2010, JPMorgan expects prices to rise as much as 120%.
The Chinese are in the largest continuing building Boom in history and are producing molybdenum-laden steel at a rate of 500M tonnes per year, USA produces about 93M tons annually, that 12% deficiency is expected to grow to a 38% deficiency within 5 years, which will likely result in the doubling of the price again.
What gems and minerals are mined in Australia?

Famous Western Australian gold mining town?
The main areas are the Kalgoorlie and Leonora regions. There are mines at Coolgardie, Leinster, Menzies, and a new gold mine at Boddington, southwest of Perth. Western Australia has several working gold mines, but its largest is the Fimiston Open Pit gold mine at Kalgoorlie- Boulder. This mine is nicknamed the "Super Pit" because it is an open cut gold mine, currently 3.5 km long, 1.5 km wide and 360 m deep. It will eventually reach 3.9 km long, 1.6 km wide and a depth of over 500 m. A complete listing of Western Australian gold mines and their localities can be found at the related link below.

How was mining used to attack a castle?
Castles are, of course designed to be resistant to attack. The battlements and loopholes in the wall allowed those inside to fire at attackers from a sheltered position, the height and placement of a castle usually allowed those inside a clear view of any attackers and there were several lines of defence inside the castle. Castles could be attacked with large catapults which could throw rocks over the walls, a battering ram, usually to break through the gates and latterly canons could try to breach the walls. Ultimately, the best form of attack would be to lay siege to the castle. This meant posting soldiers all around so that no one could leave or enter and the castle would eventually run out of food and water.
