An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted at a profit from the earth through mining; they are then refined (often via smelting) to extract the valuable element or elements.

Insitu Recover (ISR) Mining (also known as Insitu Leach or ISL) While not all uranium ore deposits are amendable to ISR, it is the preferred method to extract uranium since it is far cheaper to get the ores out of the ground and it is considered more environmentally friendly than traditional underground or open pit mines.
Apr 25, 2017· Shaft mining is employed to reach the deepest ores. There are shafts or tunnels for miners and heavy equipment to move in and out. A different shaft is used for transportation of extracted ore and an air shaft for ventilation. Slope mining is done with slanted shafts that are not too deep and helps to extract ore that occurs parallel to the ground.

But the ore''s journey to becoming a usable metal is only just beginning when the ore leaves the mine. Mining produces a mixture of rocks that contain ore and other rocks that do not contain ore. So, the ore must be separated from unwanted rocks. Then, the minerals need to be separated out of the ore.
Iron ore is the key component in steel, the most widely used of all metals. In South Africa our iron ore operations are made up of a % shareholding in Kumba Iron Ore Limited (Kumba), a leading supplier of seaborne iron ore. Kumba is listed on the Johannesburg Stock Exchange and operates three mines.

Before any actual mining even takes place, prospectors need to locate the diamond sources first. Geologists do this by following the trail of secondary diamond sources ( river beds) to determine where the primary sources of pipe deposits are. Once the pipes are found, ore samples are examined to evaluate suitability and profitability in mining.
For these reasons, iron ore production is concentrated in the hands of a few major players. World production averages two billion metric tons of raw ore annually. The world''s largest producer of iron ore is the Brazilian mining corporation Vale, followed by AngloAustralian companies Rio Tinto Group and then BHP Billiton.
To get to the bits of iron in the ore, you have to smelt it out. Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores.
