Diamond Mine Location

Where is diamond mine location?Before you know diamond mine location you must understand about what is diamond...a diamond is a transparent gem made of carbon, one of the earth's most common elements. The formation of diamonds began very early in the earth's history, when the condensation of solid matter into a sphere caused the centre of the planet to become subjected to incredible extremes of temperatures and pressure.

In the world, diamonds mine location in at least 20 countries around the world; the majority of diamonds are found in Australia, Zaire, Botswana, Russia and South Africa.

The Argyle Diamond Mine, the world's largest diamond-producing mine, is located in the Kimberley Region of north Western Australia.

Most natural diamonds are formed at high-pressure high-temperature conditions existing at depths of 140 to 190 kilometers (87 to 120 mi) in the Earth mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth). Diamonds are brought close to the Earth surface through deep volcanic eruptions by a magma, which cools into igneous rocks known as kimberlites and lamproites. Diamonds can also be produced synthetically in a high-pressure high-temperature process which approximately simulates the conditions in the Earth mantle.

Mining Guide : Learn to Know About Mining

Mining guide : First think is we must Learn about what is mining?Simple answer ; Mining is the process of extracting minerals and various materials from the earth. Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite (aluminum ore), iron ore, gold, silver, and diamonds are just some materials of what is mined. and Why Mine?We know Mining is a BIG money making business. Not only do mining companies prosper, but governments also make money from revenues. Workers also receive income and benefits. What is Principle of Mine? Mine is valuation of Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite (aluminum ore), iron ore, gold, silver, and diamonds. What are the minerals and metals important used for?Minerals and metals are very valuable commodities. For example, GOLD is a important material for jewelry business. Gold It is also used to electronic industrial. Other example is Tantalum, Tantalum is used in cell phones, pagers, and lap-tops. Cooper and tin are used to make pipes, cookware,. and.... etc. Mine Valuation ?;is Calculation of quantities of ore and classification of ore in sight.As mines are opened by levels, rises, etc., through the ore, an extension of these workings has the effect of dividing it into "blocks." The obvious procedure in determining tonnages is to calculate the volume and value of each block separately. Prospective value ?is Extension in depth,origin and structural character of the deposit,secondary enrichment,development in neighboring mines;depth of exhaustion. Large scale mining versus small scale mining?1.Large scale mining usually involves a company with many employees. The company mines at one or two large sites and usually stays until the mineral or metal is completely excavated. 2.Small scale mining usually involves a small group of nomadic men. They travel together and look for sites which they think will yield gold or another valuable metal or mineral. Where does mining occur?Mining occurs in many places around the world, including the U.S. In South America, mining is particularly active in the Amazonia region, Guyana, Suriname, and other South American countries. In Central Africa, mining devastated a National Park called Kahuzi-Biega in the eastern Democratic Republic of Congo (DRC). South Africa is also very well known for mining diamonds. Mining also occurs in Indonesia and other S.E. Asian countries. Price of Metals?is recoverable % of the gross assay value or cost of production.Unfortunately for the mining engineer, not only has he to weigh the amount of risk inherent in calculations involved in the mine itself, but also that due to fluctuations in the value of metals.
