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 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?
No, the supply of everything on earth is finite. It does not matter where.
What are facts about feldspar?
Pretty much everywhere. About 60% of the earth's crust is feldspar.
feldspar is found near volcanoes.because it it a type of igneous rock
Feldspar if found mostly in Italy, Turkey and China

Filter fabric" is a generic term used to describe geotextiles whose primary function is allowing water to pass while keeping soil fines from migrating through the fabric. US Fabrics offers a complete line of geotextile filter fabrics.
How do you remove iron from iron ore?
Iron ore comes as a mixture of Ferric and Ferrous Oxide (forms of iron oxide). At the smelter it is mixed with coke and limestone. The coke is the reducing compound. The limestone or some other substance is the flux. Coke is made from heating coal to a high temperature. The coke becomes almost pure carbon. The mixture is placed into a large brick lined open top furnace. It is set on fire.
The oxygen from iron is transferred to the coke. It turns into Carbon dioxide. The iron oxide turns into iron. The limestone mixed with the impurities in the iron ore becomes slag.
From time to time a door in the side is opened up to let out liquid iron and slag. The liquid iron is sent to the next process where it may be turned into steel. The slag becomes like glass.
What would happen if you dig to the inner core?
If someone was to dig into the inner core, the planet would be hurdled towards the sun and doomed to destruction in less than 3 seconds.
totally legit.
You can't just dig to the inner core, since any hole that you dig would collapse long before it gets that far, however, I can imagine that with sufficient technological support, you could dig a hole and install a very durable and heat resistant pipe to keep the hole open. If you could get all the way to the inner core you would have access to a virtually unlimited source of valuable nickel and iron. It would be a fantastic mining opportunity.
== == Pyrite is iron sulfide, a mineral composed of sulfur and iron. It's also known as "Fools'Gold" because of its shiny yellowish metallic luster. Pyrite can be found in sedimentary, magmatic, and metamorphic rock deposits, and also in hydrothermal vents, wherever there is sulfur and iron.
Pyrite is sometimes an ore of gold and copper. It is also an ore of sulfur, which is used in the production of tires, explosives, disinfectants, medicines, ink, wood preservatives, dyes, matches, and sulfuric acid. Some collector specimens can be quite valuable as well. The streak of pyrite is greenish-black. Pyrite is in the cubic/isometric crystal system where three axes running through the center of the crystal are of equal length and form an angle of 90 degrees at intersection.
Quartz is a mineral- it does not grow. It is found in or near most places on earth.
What is continuous phase of drilling fluid?
sometimes when we are drilling we need to use drilling fluid which are mixture of two phase like oil and gas or water and oil. In such case the fluid which is running outside is known as continuous phase of drilling fluid.
What rocks can pyrite be found in?
Pyrite could be found in any of the three rock types (sedimentary, igneous, metamorphic).
What can happen to a sedimentary rock once it's formed?
it can turn into molten rock
it can be heated and pressured and turn into metamorphic
it can weather and turn to sediments
When was iron ore first discovered in pilbara?
Iron ore reserves were discovered first by Lang Hancock. In Pilbara iron ore reserves are Plant, BC Iron, and Brockman.
After being quarried it can be "roasted" in a revolving cylindrical "oven" to produce cement. Cement is in concrete and mortar, so the limestone has helped the construction of buildings and bridges. Indeed during the last World War there were even boats made from concrete. Limestone itself can be used as the foundation for road construction, and, like other types of stone, is used to construct stone buildings and stone walls. Lime and limestone are also used in many industrial and chemical processes.
Tantalite is an ore of tantalum, which is used in specialty metals, electronics, and computer parts.
Where are the potash mines in the us?
There are Potash mines in Utah. Potash deposts are also known in North Dakota, Montana and Michigan.
What is the streak color of a ruby?
The streak of a ruby is white.
To find the streak of a ruby, or any gem stone, rub a piece of gem material on a tile and look at the color of the streak it leaves.
How do you fuel a koehler mining lamp?
There are two main series of the Koehler mining lamps. The "E" series which is the heavier regular lamp, and the Lithium series. The Lithium Series "Li16" is a much lighter lamp, more comfortable that as every new technology had its shortfalls but I believe now they are working without a problem. I believe MSHA bought a large quantity of those for their inspectors. Did that help?
