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.

How heavy is pumice?

Pumice, being mostly composed of air bubbles, is surprisingly light for a rock. So light, in fact, that it can float on water.

What are veins of gold found in rock called?

Veins of gold found in rock are typically referred to as gold veins or gold lodes. These are formed when hydrothermal fluids carry gold and deposit it in cracks and fissures within the surrounding rock.

What mine is used when ore deposits occur in veins?

Underground mining is typically used when ore deposits occur in veins. This method involves underground tunnels and shafts to access the ore deposits. Miners can follow the vein and extract the valuable minerals for processing.

Is uranium mainly found in Morocco?

Morocco is not now mentioned as a country with uranium reserves; but phosphates ores contain exploitable uranium (approx. 200 mg/kg).

Kazakhstan is the country that produces the most uranium, but large areas of uranium deposits include the area of Central Asia, Southwestern Australia, and the area around the Great Lakes.

What are five minerals mined in canada?

Canada's economy largely depends on its mineral exports. Some minerals that are mined in Canada are: coal, copper, gold, iron ore and potash.

What type of mining do Quartz process?

Quartzite is also called quartz sand, silica quartz etc. Quartzite is the major raw materials to produce quartz or silica sand.

Quartz crushing and grinding process are essential process in quartz crushing plant.
In crushing quartz plant, we use jaw crusher, impact crusher, cone crusher, VSI crusher and mobile crusher as quartz crushing machines.

Crushed quartzes are grinded into powder in grinding process using quartz powder plant. Ball mill, vertical mill, ultrafine mill are usually as machines for quartz grinding used in quartz powder plant.

How much limestone would you get in an average quarry?

This past week I visited a limestone quarry that has been mining limestone in one place for 40 years. In that time, they will have mined millions of tons of limestone. Usually nearly ALL the rock is limestone, so the answer will depend on the size (area) of the quarry, how deep you can mine, and presence of any "trash" rock.

Silicates rich in iron and magnesium are termed?

The mineral Olivine is a series between two end members, fayalite and forsterite. Fayalite is the iron rich member while forsterite is the magnesium rich member.

Is emerald a silicate or nonsilicate?

Emerald is a silicate mineral. It belongs to the beryl mineral family and is composed of beryllium aluminum silicate with trace amounts of chromium and vanadium, which give it its characteristic green color.

What is a mineral deposit that is large enough to be mined called?

An economic ore body, that's if you want to make a profit.

Early prospectors would extract shallow deposits of ore by?

panning for gold in rivers and streams, using a pan to separate the heavier gold particles from the sediment. This method was effective in finding surface-level deposits of gold and other precious minerals. It was a labor-intensive but relatively simple process that allowed prospectors to quickly identify potential gold-rich areas.

What is the impact on silver mining of the environment?

Very little. Most silver is mined in deep shafts below the surface and refined in smelters which do not have chemical residues. The tailings can be slightly radioactive, but overall low environmental impact

Is gypsum a carbonate?

No. Gypsum is a calcium sulfate dihydrate.

Which island produces 25 percent of the worlds nickel?

New Caledonia is the island that produces 25 percent of the world's nickel.

How is brown coal mined?

Brown coal, also known as lignite, is typically mined through open-cut or surface mining methods. In this process, the topsoil and overburden are removed to access the coal seams below the surface. Brown coal is then extracted using excavators, bulldozers, and other heavy machinery before being transported to a processing plant for further refining or combustion.

What is the mineral falcondoite mined for?

Since 1976, at least two new mineral species for the Geosciences have been discovered in Falcondo mine (Dominican Republic), being both approved by the International Mineralogical Association (IMA). The first discovery was in 1976 and this new mineral specie was named "Falcondoite" (honoring Falcondo mine) which is the Ni analogue of Sepiolite and with the corresponding IMA 1976-018 approval.

Falcondoite is one of the best sources of Ni for laterite mines where pyrometallurgical process is used for ore benefitiation, with average NiO up to 27%.

It is one of the most beautiful minerals, and can be used as semiprecious stone too, for jewelry, souvenirs, biscuits, etc.

Is ilmenite and rutile are iron ores?

Yes, ilmenite and rutile are sources of titanium, not iron. They are titanium-bearing minerals commonly found in beach sands.

How is soil erosion dealt with in zimbabwe?

In Zimbabwe, soil erosion is addressed through various measures such as terracing, agroforestry, and contour plowing to reduce the impact of rainfall on soil erosion. Additionally, promoting sustainable land management practices, such as conservation tillage and crop rotation, helps to improve soil structure and reduce erosion risk. Community education and awareness programs also play a crucial role in promoting soil conservation practices among farmers.

Which state in India has the world's largest deposit of thorium?

Kerala, a state in southern India, is known to have the world's largest deposit of thorium. Its monazite sands contain significant amounts of thorium, a valuable radioactive mineral used in nuclear technology.

What is Galenas luster?

Galena is a metallic mineral that has a bright, shiny metallic luster when freshly broken. Over time, the surface can tarnish and become dull.

What are mining advantages?

This is what I have found so far

1) More jobs are available so employment levels will increase in the local areas

2) It will increase the income of the area through things such as tax and substantial profits

3)Golds, diamonds and ores, such as uranium, that are found, supply the national government with trading goods meaning even more money will be made.

4)The golds, diamonds and ores are also used for product manufacture as we use electronics, such as computers and other items, containing these substances on a daily basis.

If I can find any more I'll come back and improve my answer but I hope this is helpful!

How does gold mining effect the landscape?

That depends on the mine. Most new mine operations have no detremental affect and can actually improve there area. While it may add some cost to the price of materials from the mine, they can be very good for the local economy and environment.

I met a mine owner from Missouri a few months back while flying. I have never met a more pro environmental human in my life. His views on the environment were inspiring!

What do mine operators do to fix land that has been strip mined?

To strip mine, the mining operation requires the removal of the overburden. That's all the stuff on top of the material that the mining company wants to extract. With the overburden removed, and the material removed, overburden is replaced and suitable surface cover is re-established. Some thought and planning are included in coutouring the surface to "match" the area around it. The mining company might plant trees, shrubs or just sow grasses on the land, according to the nature of the surrounding vegetation, and also their agreement with the regulators who will inspect the finished operation.

Where is the world largest thorium deposits found?

The largest thorium deposits in the world are found in Australia, India, and the United States. These countries have significant reserves of thorium that could potentially be used as a source of nuclear energy in the future.

What is the name of a deep hole dug for mining?

A deep hole dug for mining is called a shaft. It provides access to underground mineral deposits for extraction and transportation to the surface. shafts can extend vertically or at an angle depending on the depth and layout of the mine.
