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.

Why doesn't India buy uranium from Canada?
Because India has his own uranium (and also thorium) resources.
Difference between Online analytical processing and data mining?
online analytical processing uses basic operations such as slice and dice drilldown and roll up on historical data in order to provide multidimensional analysis of data
data mining uses knowledge discovery to find out hidden patterns and association constructing analytical models and presenting mining results with visualization tools.

What kind of rock do they make marbles out of or used to make marbles out of?
Take a look at the related link I have included below. It is very informative and explains how marble rock is formed and what it comprises of.
It is possible you may mean CALICHE. If so, it is a very hard, cemented soil that, depending on where you are, may contain carbonates or nitrates.

How is Silicon extracted from Sand?
ndustrially, silica is converted to pure silicon by heating it with coke (the form of coal, not the drink) in a furnace. But there's an even easier, if less cost-effective, method that I learned from Jason Stainer, a science teacher in England. All you have to do is heat a mixture of common silica sand and magnesium powder in a test tube. The magnesium steals the oxygen atoms from the silica, leaving elemental silicon.
No reaction is perfect, and in this case you're left with a mixture of magnesium, magnesium oxide, magnesium silicide and silicon in the bottom of the test tube. Fortunately, the best way to purify it is also the most entertaining. I told my eight-year-old Harry Potter fan that I had prepared a fire potion.
First pour one cup of what is sold in any hardware store as muriatic acid (37% HCl) into five cups of water. (Not the other way around. The old chemist's saying "Do as you oughta, add acid to watta" is there to protect you from steam explosions that can occur if water is poured into acid instead of acid into water.) Then dump in the contents of the test tube, and you'll get a wonderful frothing mass of flaming bubbles and a lovely mushroom cloud of smoke. This is one of the best can't-fail fire potions. (

Perhaps you mean Michael Moore ? He is a documentary film maker.
What cost more gold or platinum?
Gold. It is more expensive according to how much mass it has inside of it.
How much palladium has been mined in human history?
As of the End of 2004, total palladium mined was estimated at 3,781.5 tons. Given annual production is now around 222 tons pa, total mined in human history at the end of 2009 would be around 4,890 tons.
How did gold hydraulic mining work?
Hydraulic mining used a water cannon (called a monitor) to wash the hillside down and into a huge sluice box which separated the Gold from the dirt and gravel.
What problems were caused by mining booms?
The beurocracy didn't like poor people having money as they may have revolted and overthrown the oligarchs.
How was gold mined in the 1850s?
In the 1850s, there were numerous methods for mining 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 were the concerns of russians who opposed the kamchatka mining operation?
Russians that opposed the Kamchatka mining operation did so because of concerns they had for the environment. They contended that the operations would hurt the wildlife and contaminate water sources.
