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.

What do you do with mail that is not mine?
Write on the envleope "Not at this address - Return to Sender" and out back in mailbox for return.
Why is open pit safer then shaft mine?
it cant collapse in the way shft mines can. As Shaft mines are underground it makes it alot more easier for it to collapse on everyone and they will all die so therefore open pits are much much safer than shaft mins. Thanks
What are the disadvantages of underground mining?
Underground mining is very expensive to conduct. It requires management of a fresh air supply, along with drainage. Underground mining can only remove a portion of the mineral present (the rest is holding up the roof).
You could get trapped and die.
What minerals like quartz that break into pieces with jagged edegs have?
Minerals like quartz that break into pieces with jagged edges are typically classified as having a conchoidal fracture. This type of fracture produces smooth, curved surfaces with sharp edges resembling the shape of a clam shell, hence the name "conchoidal." Other minerals with conchoidal fracture include obsidian and flint.
What is a large pile of rock and debris left by a receding glacier?
A large pile of rock and debris left by a receding glacier is known as a moraine. Moraines can consist of different sizes of material, from clay and silt to boulders, and are typically deposited along the sides or at the terminus of a glacier.
Which country has the highest uranium deposit in the world?
Australia has the highest uranium deposits in the world, with significant reserves located in several states across the country. It is estimated to hold about 30% of the world's known uranium resources.
Mining is not a field in which France competes, and only a very minor fraction of the labor force (less than 1 percent) is engaged in mining. Regarding coal, 2 major fields produce most of France's coal: the Lorraine coal field near Metz and the Nord-de-Calais coal field near Lille. Most of these fields do not have economically viable reserves compared to other big producers because they lack sufficient amounts in some cases or are difficult to extract. Many coal fields have shut down since the 1950s.
France is among the biggest producers of bauxite in Europe and also plays a big role in the continent's natural gas production. France's position may be threatened, however, if some Asian companies acquire access to the European market, although the tariff -free regulations that EU member states enjoy put France in a strong position. France is an importer of petroleum but processes petroleum at home to produce several oil products which are sold domestically and abroad.

Diatomite is High in Silica, Absorbent, Porous, Long Lasting, Environmentally Friendly, pH Neutral, Sterilized, Natural and Reusable, all factors necessary for health plants, while still being cost effective for the grower. = What are the Benefits of Using Diatomite? = ---- High Silica Content: Silica is essential for healthy plants and roots. While Diatomite is approximately 85% insoluble Silica, it contains a small but significant portion that is SOLUBLE SILICA. Silica is essential for healthy plants and roots. Your plants will receive from Diatomite a slow release of silica resulting in healthier, more robust plants. Plant available silica has been shown in studies to stimulate SYSTEMIC ACQUIRED RESISTANCE (SAR) in plants which increases their resistance to disease. Absorbency & Porosity: Diatomite is naturally very porous, and can hold 150% of its weight in water. The Silica Content, natural Absorbency, and Porous qualities result in a slow release of water and nutrients to your plants, contributing to higher yields and less watering. Capillary Action & Lateral Movement: The porosity of the Diatomite contributes to its ability to draw water, while moving water and nutrients laterally throughout the medium, making Diatomite ideal for Hydroponics! Air Penetration: Diatomite is multifaceted and varies in size. Because each rock is unique in shape it does not compact while in the pot. This leaves pockets, allowing air to penetrate and circulate to the root zone. Sterilized, Non-Toxic, pH Neutral: When Diatomite is mined it is heat treated to over 600 degrees Celsius, making it completely sterile and safe for all of your planting needs. Whether you are using 100% diatomite or you are adding it to a mix of your soil it will not contribute to changes in pH. Environmentally Friendly: Diatomite is a fossil, making it natural, safe and an Environmentally conscious alternative. We have visited the mine in Australia, and we are confident that the practices used to mine our product are safe and in accordance with Australian environmental guidelines. Long Lasting, Natural & Reusable: Diatomite is inert and will not break down or decompose like other growing mediums. It is Natural and completely reusable. When dry, diatomite is extremely lightweight, making it ideal for plant shipping purposes. Because it is Reusable and Long Lasting it is economical and cost effective for long term use.
Mining has not stopped, because otherwise we could not get diamonds or emeralds etc!
Where do most profits from mining minerals in many African countries south of the Sahara go to?
To the African Govt.
What is meant by primary and secondary snow belts of the greater Cleveland Area?
Secondary snowbelts is an area in Northern Ohio were snow occurs maily when winds are directly from the north; i.e. Lorain, Medina, and the northern halves of Summit, Portage and Trumball counties. Areas bordering these counties also receive lake-effect snow, altough to a lesser extent.
Lake, Geauga, Cuyahoga (mainly the eastern half), and Ashtabula counties get much of the lake-effect snow in Ohio every year. For this reason, these four counties are known as the PRIMARY SNOW BELT. Snows in this area result when very cold winds from the west, northwest or north blow across the unfrozen lake.
What problems can be caused when mining?
The problems caused by mining are:
water pollution
plant and fish habitats being destroyed
dangerous job
hard work
When was the Bessemer steel process discovered?
The Bessemer process was the first inexpensive industrial process for the mass-production of steel from molten pig iron. The process is named after its inventor, Henry Bessemer, who took out a patent on the process in 1855. The process was independently discovered in 1851 by William Kelly. The process had also been used outside of Europe for hundreds of years, but not on an industrial scale. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten.
Marl as lacustrine sediment is common in post-glacial lake bed sediments, often found underlying peat bogs. It has been used as a soil conditioner and acid soil neutralizing agent.
Your answer depends on the diamond mine you reference. Most diamond mines are owned by different companies.
For example, in Canada, from their Wikipedia page:
"The mine is owned by a joint venture between the Rio Tinto and Dominion Diamond Corporation, and is operated by Diavik Diamond Mines Inc., a subsidiary of Rio Tinto Group."
In Australia, the Argyle Mine is owned by the Rio Tinto Group.
In Russia, the Udachnaya pipe is owned by Alrosa.
In Africa, The (Botswana) Orapa diamond mine is owned by Debswana.

A mining makes about more than a millon dollars a week in a year average is around one billon It also dpends on how lucky you are to find gold and rocks
When did the mining industry start?
it started sometime during the 19th and 20th century.
or
In the Ancient Orient a unified China recorded in detail mining for profit. Later similar Egyptian, Greek, Roman, and other peoples operated mines near 2,000 BC as recorded in Egyptian scrolls.
This question depends on what type of mining. Modern - Industrial Revolution Mining began in the late 1700's. By the 19th Century large mines were operational around the World. Seeking Gold for Tribal Art with basic tools has followed the history of human development.
