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.

Most pyrite is not valuable (I have heard estimates of 50 cents (USD) per gramme). Some pyrites contain traces of gold that increase its value, but it is mainly used for industrial extraction of sulphur. Large, perfectly cubic crystals of pyrite are valued by museums as exhibits.
Compare surface and subsurface mining?
Surface Mining
easier than subsurface mining
does more damage to environment
creates more of a mess
Subsurface Mining
it is very dangerous
you retrieve minerals from underground
you have very little air underground

Why were railroads so important for miners and the mining industry?
In the US and in many parts of the world, railroads are the main form of transportation for various types of minerals and ores that are part of the mining industry. With proper transportation, the miners have an ongoing way to transport the products mined from the earth. Often the railroads lead to a water port and the mining products can be shipped via waterways, canals and seas to their proper destination.

When was the gold rush in Alaska?
Gold had been discovered by Russian Colonial explorers as early as 1848 but it never amounted to anything until 1870. In 1880 Joe Juneau, Richard Harris and Chief Kowee made their find at Silver Bow Basin beyond Gold Creek. In 1886 the Fortymile River discovery touched off the first gold rush and produced about 500,000 ounces of Gold (including a 56.8 troy ounce nugget). In 1896 the Chicken Creek discovery was made but in August word reached the miners of the Klondike River Strike (where in the next three years, 1,200.000 ounces were extracted) and the race was on to Canada. In 1898 the Porcupine Creek discovery was made. In more modern times gold is still being found in and produced in Alaska.

Which country is the biggest gold producer in the world?
which country has the highest gold reserve
you can find the U.S. world statistics at the USGS. Bigest country producer :
* south africa * USA * China * Peru * ...
I would say that the countries who lead gold are USA, South Africa for there reserves and also because the bigest mining companies are located there (Rio Tinto is from the UK...).
The mining companies have a major role as they hold the supply side... and this way control the prices. They can short term reduce or increase production and long term through investment in explotation and exploration.

What was the most popular method that prospectors used to mine for gold?
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.
