Deepest Mines In The World

A mine is a term used to refer to a pit in the soil from which metal ores and other valuable minerals are extracted. As we know gold is very expensive, and therefore the gold miners need desire to extract merely 0.35 particles from a mountain of any rock formation to obtain a profit. Daily, more than 4,000 workers descend into the gold mines through pulleys, or, as they have also been called in mining idioms, in their "bird cages". The top three deepest mines, according to their global rankings, are looked at below. Each of these are in South Africa.

Mponeng Gold Mine

Mponeng Gold Mine is located to the southwest of the city of Johannesburg in South Africa, and is presently one of the deepest mines in the world. The ownership of the Mponeng gold mine lies with the firm AngloGold Ashanti. The depth of the mine is around 4 kilometers inside the earth. The functioning depth of Mponeng mine is ranged from among 2.4 kilometers to a further extent of 3.9 kilometers lower to the ground. Mponeng mines abstract the Ventersdorp Contact Reef (VCR) in the region of West Wits in South Africa.

The deepest mine under the ground at Mponeng works with the sequential "grid iron method" of mining. In this method, the ore which is mined is preserved and melted at the gold plant of Mponeng’s mine. Firstly, the ore is initialized down towards the ground with the help of the semi-autonomous process of milling, and then a conservative gold filter process including liquefied oxygen dose is smeared.

TauTona Gold Mine

TauTona is listed as the second deepest mine in the world. The TauTona gold mine is 3.9 kilometers deep. Though mining at TauTona presently takes place at the depths extending from within 1.85 kilometers to 3.45 kilometers deep, and its mining depth was prolonged to 3.9 kilometers concealed with the accumulation of a subordinate shaft. The mining operation of TauTona hence begins with the overall construction of around 800 kilometers of passageways. Now, the mine is at this time functioned with the three shafts.

The ownership of this mine is held by the AngloGold Ashanti company, which has started fluctuating its methods of mining at TauTona between "long wall" and "dispersed grid" mining. TauTona's life of the mine is predicted to end up soon. This mine produces nearly 189,000 ounces of the gold for many years. The mining operation of TauTona is accompanied at the range of 1.8 kilometers down towards 3.9 kilometers. The plant customs conservative milling to break the mineral, and a "carbon in plant" (CIP) is used to work up with the mine. When carbon is added, it transfers to the plant at Mponeng for the processes of "electro-winning" and melting before the final retrieval of gold is complete.

Savuka Gold Mine

Savuka Gold Mine reaches a depth of around 3.7 kilometers into the earth. This mine is also found in the West Wits area of South Africa and is operated by AngloGold Ashanti. It is the third inmost mine. The method of mining for Savuka gold mine is converted to grid mining. Savuka gold mine produces 37,000 ounces of gold for a year. This mining process includes three-shaft system. The methods included in the mining are sequential grid mining, conventional mining and long wall mining. The working temperature too is tolerable for the workers. The plant of the gold mine includes a conservative mill circuit, which breaks the mine into an appropriate size. The breaking of the mine further nourishes into a Carbon-In-Pulp route.
