Deposit

iron ore
Iron ore is a rock containing iron veins. The separation of iron ore and iron melting occurs. Fe chemical symbol for iron.

Deposit
Instead of natural accumulation of ore, or ore mine say. Now the separate definition of mineral resource and mineral resources as defined by the classification criteria. In a deposit, there is a particular ore. Most deposits are named based on criteria such as the location (eg, Vytsvatrsand, South Africa), or the name of an explorer (eg Kambalda nickel), from the luxury, a historical figure or a prominent person, or Aznamhay mythological (Phoenix, Kraken ) or name of company code that it found (eg MKD-5 for Mount Keith nickel).

Classification of deposits
Deposits according to various criteria developed through the study of economic geology or ore genesis classified. The usual assortment is as follows.

Epigenetic hydrothermal deposits
Mesothermal vein gold deposits, examples of which Golden Mile, is Kalgrvly.
Conglomerate hosted gold-uranium deposits Rkayn, such as Elliot Lake, Canada and the Witwatersrand, South Africa
Carlin type gold deposits,
Stuck in the form of epithermal vein deposits Framework

Porphyry copper deposits + / - gold + / - Mo + / - Silver
Intrusive Related Gold and copper deposits + / - (tin, tungsten), typified, Arizona
Hydromagmatic magnetite iron ore deposits and skarn
Skarn ore deposits of copper, lead, zinc, tungsten, etc.

Nickel-cobalt-platinum deposit
Magnetite ore nickel - copper - iron - PGE includes:
Or platinum-bearing magnetite or chromite deposits vanadiferous mass
Hard rock deposits of titanium (ilmenite)
Kvmatyt host deposits of nickel - copper - PGE
Subvolcanic feeder subtype, such as Norilsk Tanak and the Thompson Belt, Canada
Intrusive deposits of nickel - copper - PGE, such as the Gulf Vvazy in Canada and Jinchuan in China
Lateritic nickel deposits, examples: Guru and Kvjh, Philippines and Rvnztrvp in Western Australia.

Reconstruction deposits Metamorphically
Scrip form (Podiform) iron oxide hosted serpentine, chromite paramagnetic, like Wild River, Tasmania Vkansar chromite ore Kvbyna
Broken Hill Type Pb - Zn-Ag, a kind of SEDEX deposits are considered to be restored
Carbonatite - related alkaline igneous
Tantalite Vrmykvlyt- phosphorus (Falabvrva in South Africa)
Rare earth elements - Mount Weld in Australia and expressed Obo in Inner Mongolia
Diathermy kimberlite hosted diamond, Lamprvyt or Lamprophyre

Sedimentary deposits
Close-up of Banded Iron Formation specimen from Upper Michigan. Scale bar is 5.0 mm.
Iron ore banded iron models, including:
Channel deposits of iron or iron ore Pysvlyt
Heavy mineral sand deposits and sand dunes with deposit
Alluvial deposits of gold, diamonds, tin, platinum or black sand deposits
Alluvial deposit zinc oxide, such as the Scorpion

Hydrothermal sedimentary deposits
SEDEX
Lead, zinc, silver, like Red Dog, McArthur River, Mount Isa, etc.
Arkose strata of shale-hosted copper, Zambia's copper sample.
Tungsten strata, such as deposit Erz Mountains, Czech Republic
Split exhalative hosted gold deposits Chert
Mississippi Valley type deposits (MVT) lead-zinc
Hematite deposits from forming a band Azahn
Related ore Astrobleme
Nickel and copper, Sudbury Basin, Ontario, Canada

Extraction
Extracting oil deposits involves the following steps:
1. Explore to find and then determine the value of the ore that is in place ("lump ore")
2. Resource estimate for the math to estimate the size and grade of the deposit.
3. Economic pre-feasibility study to determine the deposit from the perspective of the theory that early detects whether further investment in estimation and engineering studies is required and key Nyzkhtrat and define areas for further work.
4. Conduct a feasibility study to evaluate the investment operations, technical and financial risks, project coordination and decision-making to be done or drop a proposed mine project. This section includes mine planning to evaluate the economically recoverable ore sector, metallurgy and processing of ore, ore concentrates market and profitability, cost engineering, cost of infrastructure and crushing, the needs of stakeholders, analysis of the beginning By the end of the deposit, from start drilling by the end of the earth to restore the situation before the operation.
5.gstrsh for creating access to the ore mass and plant and equipment.
6.bhrh dynamic operation of the deposit.
7. Restoration and reclamation of land to the state before the operation for later use.

to trade

And metal ore imports in 2005
Ore (metal) international trade and a significant proportion of international trade in raw materials as well as the volume to be allocated from the perspective of value. The reason is that it is unequally distributed around the world and around the peaks ore demand and infrastructure are processed.

Most base metals (copper, lead, zinc, nickel) on the London Metal Exchange traded at the international level, and the size of reserves and minor metals trading by
کومکس (COMEX) Vnymks (NYMEX) in the United States and the Shanghai Stock Exchange (Shanghai Futures Exchange) take place in China.

Iron ore between the manufacturer and the customer sales, despite the different prices for three months between major mining conglomerates and major consumers will be determined, and this is the basis for smaller companies.

Other commodities firm international base prices are, in most cases the price is agreed between suppliers and customers. In general, this means that determine the price of the ore is opaque and difficult. Such metals include lithium, niobium, tantalum, bismuth, antimony and rare earths. Many of these goods are dominated by one or two major suppliers with more than 60% of world reserves. London Metal Exchange aims to add uranium to its list of metals.

According to the World Bank, China was the top importer of ores and metals in 2005 and then the country of United States of America and Japan.
