Mining

Realgar is an orange-red mineral used in pyrotechnics and as a pigment for tanning.

Tin is separated from tin ore through a process called smelting, where the ore is heated with carbon in a furnace to create tin metal. This process allows the tin to be separated from the other impurities in the ore, resulting in pure tin metal.

Yes. There is an enormous amount of mineral resources in the Himalayas. Mining has been occurring there for centuries and then transported all over the world through the Great Silk Road. One of the royal crowns has a Spinel (ruby) the size of a golf ball that was mined from the Himalayas. Due to the extremely rough terrain, modern mining has been kept to a minimum in Nepal and Bhutan which lack the infrastructure and financial resources required for large operations. Many outside companies have tried setting up shop there but few have worked out. Another thing limiting the mining in Nepal and Bhutan has been the importance placed on not impacting the environment which is ingrained in their Tibetan roots. They mine for; Iron, Limestone, numerous rare gems (some found only in the Himalaya), Granite, Dolomite, and many others

India has the largest reserves of thorium in the world, followed by countries like Australia and the United States. Thorium is a naturally occurring radioactive element that can be used as a fuel in nuclear reactors.

mafic because it is-dark colored. Ultramafic - no light colored mineral which means it it attracts most heat from a volcano taking it longer to cool down from the lighter, in between substance known as felsic :D

Gallium is not found free in nature, and it is present in only ppm (parts per million) quantities in minerals. For that reason, we recover gallium (III) salt as a byproduct of bauxite (a chief ore of aluminum) and sphalerite (a primary ore of zinc) processing. In either case, gallium chloride (GaCl3) is the salt we generally extract. Recovery of gallium from other sources is negligible. Use the link below for more information on this interesting poor metal.

China is the largest producer of neon in the world. The country accounts for a significant portion of global neon production due to its large chemical industry and manufacturing sector.

I can't bother to write the right answer, so this is it:

No, azurite is not metallic. It is a copper carbonate mineral that typically exhibits a bright blue color due to its chemical composition.

The general answer is that some things are underground, and recovering them by removing material covering them up is not practical. A lot of coal is mined by removing overburden (the stuff covering the coal seam) and then, after the coal is removed, replacing that material to reclaim the land. We also see gigantic open pits were we recover copper and other minerals. But in the case of some minerals, particularly precious ones, we have to follow a seam or vein to recover metals, precious stones or the like. We need to point out that a quarry is generally a term applied to an open pit or surface excavation from which material is extracted. Mining includes open pit or surface mining, and also underground mining, which is generally at least an order of magnitude more dangerous. Hopefully the question was asking why some minerals or materials were taken from the surface, and others were removed from shafts or drifts or a combination of them.

Sapphires are commonly found in countries like Myanmar, Sri Lanka, Madagascar, and Australia. Additionally, they can also be found in parts of Africa, North America, and certain locations in Europe. Each region may produce sapphires with unique qualities and characteristics.

Zircon can be found in various geological settings, including igneous rocks like granite and syenite, as well as in metamorphic rocks and sedimentary deposits. It is commonly mined in countries such as Australia, Brazil, and South Africa, where it is extracted for use in jewelry and industrial applications.

There are 11 major producing diamond countries in the world today. The Catoca Diamond Mine in Angola, for example, is the 4th largest diamond mine in the world and is one of about 35 active diamond mines in Africa, Russia, Australia, Borneo, and Canada.

The waste products in copper mining include tailings, which are the leftover material after the desired copper ore has been processed and extracted. These tailings can contain harmful chemicals and heavy metals that can impact the environment if not properly managed. Mining operations must carefully manage and dispose of these waste products to minimize their environmental impact.

Myanmar has the largest deposit of jade. The country is known for its high-quality jadeite, which is a valuable gemstone and is predominantly found in the Hpakant region in northern Myanmar.

You can, but you need heat and charcoal.

Tin = Sn

Carbon = C

Oxygen = O2

SnO2 (tin oxide/tin ore) + C = Sn + CO2

You need to melt the tin ore and charcoal (made of C) together, and the carbon will take the oxygen from the tin oxide, creating carbon dioxide and tin. Voila, have your tin, and your waste compound, carbon dioxide.

When a molecule absorbs visible or ultraviolet radiation, electrons in their ground state are promoted to higher states. Through various types of decay, the electrons fall back to their ground states. During this process, some infrared radiation is emitted, which is felt as heat. Black materials emit more infrared radiation because most of the decay of electrons from excited states to ground states involves infrared radiation emission.

A banded stone is also known as an agate. Agate is a type of chalcedony quartz that is characterized by its banded or layered appearance, often featuring various colors and patterns. It is a popular material for jewelry and decorative objects.

Platinum ore typically has a silver-white color and is denser than palladium ore. A chemical test using aqua regia can help differentiate between the two ores, as platinum is more resistant to being dissolved by aqua regia compared to palladium. Additionally, the presence of other minerals in the ore can also help determine whether it is platinum or palladium.

Beryl does not have a set amount of sides.

Cracking is important in oil refining because it breaks down larger hydrocarbon molecules into smaller, more valuable ones such as gasoline and diesel. This process increases the overall yield of high-demand products and helps to optimize the use of crude oil feedstock. Additionally, cracking can improve the efficiency and profitability of the refining process.

Calcium and magnesium are naturally occurring elements that are commonly found in mineral deposits, rocks, soil, and water sources. They are essential nutrients for plant and animal health, and are typically obtained through dietary intake from sources such as dairy products, leafy green vegetables, nuts, seeds, and certain types of fish.

This is an example of metamorphism, which is the process where rocks undergo changes in response to heat, pressure, or other factors without melting. Shale turning into slate is a common metamorphic process that involves the recrystallization of minerals to form a denser, more compact rock with a characteristic foliation.

Froth flotation is commonly used in mining to separate valuable minerals from ores. Examples include the flotation of sulfide minerals such as copper, lead, zinc, and nickel from their respective ores to produce concentrates. It is also used in the processing of coal, where froth flotation is employed to remove impurities and achieve higher thermal efficiency.

The process of separating useful metal from other elements is called metal extraction or metallurgy. This process involves various techniques such as smelting, leaching, and electrolysis to isolate and purify the desired metal from its ore.
