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.

Where can you dig for Amethyst?
Almost all the African countries are famous for producing best quality gems. However, the top quality amethyst mines are located in Zambia. Brazil and Argentina in South America are the other places which have several amethyst mines, but the gem color is lighter.
Historically many of the best amethysts come from Russia, hence even today the top quality amethysts are called "Siberean" amethysts.
The other minor places where amethysts are mined include India, Canada, Madagascar, Mexico, Myanmar, Namibia, Sri Lanka and Tanzania.
How do crystal shapes help us?
Well, unless you're a crystallographer or geologist, they don't really do much for you at all.
If you're one of those, then the crystal shape can either help you understand how the crystals grow (for the former) or help you identify the mineral (for the latter).
the mining of ore is when you get ore from a rock you mine anywhere in runescape.
Does pyrite have any special properties?
It can be sold as "fool's gold" and it's shiny, hard and not too dense :-)
Acid mine drainage is the low pH created by microorganisms convering sulfides and sulfates in tailing from the ore processing into sulfuric acid.

How is aluminum extracted from the earth and processed?
Aluminum ore is called Bauxite, which is a heterogenous mixture of aluminum hydroxide minerals (mainly gibbsite, with some boehmsite and diaspore) bound in a matrix of clay, silica, silt and other metallic hydroxides. It is usually found near the Earth's surface, and so strip-mining and pit mines are the typical methods of extraction. The production of metallic aluminum requires two steps. First the Bauxite ore has to be converted to a mineral called Alumina (aluminum oxide Al2O3), by a method called the Bayer process. In this process, the Bauxite ore is treated with hot sodium hydroxide solution (2NaOH + 3H2O), which dissolves only the Alumina from the Bauxite. The process is completed by cooling the "Bayer liquor", drying the residue, and then reheating (calcining) the residue to obtain nearly pure Alumina. Aluminum metal is obtained by electrolysis of the Alumina using the Hall process (Hall-Héroult process). The Alumina is dissolved in liquid Cryolite (Na3ALF6) at a temperature of over 1000oC, and then a low-voltage high-current electrical field is used to separate the aluminum from the oxygen and Crylolite. The voltage in a Hall cell is only 3-5 volts, but the current is typically 200,000-300,000 amperes. Because the liquid pure aluminum metal is denser than the Cryolite, the metal collects at the bottom of the cell where it can be periodically drained out and cooled. In the early 20th century, over half of the world's Bauxite was mined in Arkansas. Now the USA produces virtually no domestic Bauxite and is an importer of the ore. Nearly 50% of the Alumina used in the US in 2008 was imported from Australia. Other major sources of Bauxite and Alumina are Guinea, Jamaica, Brazil, China and India. The production of aluminum metal uses a tremendous amount of energy. The recycling of existing aluminum products is the most cost-effective way of obtaining aluminum metal for future use, being far less expensive than processing Bauxite and Alumina.
Where can you find a place to melt ores on runescape?
Look for "furnace" on the World Map. There is one north of the Lumbridge Palace; there are several more in different parts of Gielinor.
How do you get the mining gear on Pokemon Diamond and Pearl?
you have to talk to all the people in Eterna city after you beat the gym leader.
I think he is particularly on the middle road that leads downward to cycling road
How is Halite extracted from the Earth?
Halite (NaCl) is extracted by mining or from seawater by crystallization/recrystallization.
The term, "Teller mine" is still used today to describe a similar shape land mine.
A related item, the "bouncing Betty" was a small anti-personel mine. When tripped, it would jump into the air and explode, sending dozens of small balls in every direction.
Totally unrelated, Edward Teller was nuclear scientist who was called "the father of the Hydrogen bomb" (the nuclear bomb that was the upgrade from the atomic bomb developed during WW2).
Which has more mass quartz or pyrite?
There's no way to answer your question. More accurately, there is no way to answer your question without sounding like a smart-ass. We can't tell which has more mass unless we know how much of each you have to begin with! If you've got a pound of quartz and 10 pounds of pyrite, the pyrite is more massive, because objects with greater mass have greater weight. If you've got only an ounce of pyrite, your one-pound sample of quartz is more massive. Here's a question for you: What weighs more, a pound of feathers or a pound of rocks? Many people who answer too quickly say, "Rocks." And they'd be wrong. Since both weigh a pound, they have the same weight and, therefore, have the same mass. In other words, they both contain the same amount of matter. Perhaps what you meant to ask is What has the greater density? Density is mass per unit volume. So, if you had, say, a cubic foot of quartz and a cubic foot of pyrite, then you could ask Which is more massive? or Which has greater mass? That would be a question we could answer definitively. Quartz has a density of about 2.65 grams per cubic centimeter. Pyrite's density is about 4.9 g/cc. So a cubic centimeter of pyrite is more massive than a cc of quartz.
Well... The Lumbridge mine has no gold... The mine west of the Lumbridge mine has no gold... The mine near the Champion's guild has no gold... the mine east of the dark wizards has no gold... and I don't think the dwarven mine has any gold.
I hope those are the answers your looking for =)
What did the Jupiter Mining ship Red Dwarf Mine?
Alternative sources of energy
AnswerRed Dwarf does the extended run to the outer planets, it is one of the medium haul vessels collecting various minerals in the form of ores from the moons of Uranus and Neptune primarily. Much of its mining equipment takes the form of rock blasters and ore-scoops, it is not usually mining those elements and minerals which occur raw in seams: there are more specialist teams with different equipment doing that. However, because it is a great investment of time and money to get the ship out there from the inner gas giants (given that it is a ship based in the Jovian system,) the mining crew will tend to return a great bulk of raw rock and ore, sorting it through during the return journey. The variety of material collected is used for many things, including energy, industry, construction and scientific uses. You don't want to hang around on many of those moons, they're pretty inhospitable and suits are harder to maintain that a chunky ship, which explains the lack of discrimination in the collection. AnswerOn the contrary, Red Dwarf is a deep-space vessel. The high level of technological advancement clearly present in Red Dwarf would be completely incompatible with taking years to get from one part of the solar system to another. They go into hyperdrive, for heavens' sake! As for what it mines, it seems evident to me that it mines asteroids. The claw at the bow is obviously to latch on to an asteroid while the mining machines extract its resources.How do you unlock - mining laser in where's my water?
Much like unlocking the planetarium, the mining laser level can be found by forcing the screen upwards in the challenges section of "cranky's story"... It's a little skull icon sketched in the top left corner of the screen:)
In what form is phosphate rock mined?
All of the U.S. production of phosphate minerals--and 90 percent of worldwide production--was the sedimentary phosphate rock known as phosphorite, which was largely comprised of carbonite apatite
How do waves deposit sediment on the coastlines?
they wash in the sand at the ocean floor that is then called "deposit" I THINK
Where do people that mine gold sell their gold?
Grand Exchange in varrock
Many small miners sell to Licensed Gold BuyersThe laws in many countries are designed to make sure their government can collect a fee when the gold is sold. The governments tax or fee is often about 4% of the selling price.In the Capital City of each mining country there are gold buyer and sellers. In some there are stores where you bring your gold to sell. From the mine, gold is usually ingots or gold dust, in which the gold content might be 60% or 70%.
Refiners often charge 3% to 5% for Refining.
The Prices used in a Capital City might be as much as 20% below the New York and London prices. Often it makes money to ship to the US or UK to a refiner there to sell, getting usually about 95% of the world market price. About 2% to 3% is lost in the refining process.
Moderate to large mines sell to Refiners or Refine ThemselvesThe way to get the full world market price is to have .999 fine gold bars in standard sizes. Even a relatively small sale, like 100 ounces, can often get 95% to 97% of the world market price adjusted for what is lost during refining.

They are a kind of minerals, and historically some people have called them "fool's gold" because they are similar in appearance to gold, although they are not gold at all.
Is there an endless supply of iron ore in Minnesota?
