New gold mining technology to boost South African
A new method of underground gold mining, being tested by AngloGold Ashanti, is filling headlines in the country, as the method has the potential to reverse the decline in South Africas gold output.

Miners, mining materials and equipment are transported deep underground via the mine cage in the vertical shaft, which can go to depths of up to below the surface. Openpit gold mining also takes place in South Africa. This is a mining technique which excavates at the surface to extract ore.
#0183;#32;For 130 years South Africa has been exploiting its gold resources in Johannesburg. But at what cost? 278 abandoned mines and 200 mining dumps, that contain about 6 billion tons of waste, exist in Johannesburg. For every single gram of gold extracted, 200 kg of waste are produced.

South Africa South Africa Gold mining: Prospectors established in 1886 the existence of a belt of goldbearing reefs 40 miles (60 km) wide centred on presentday Johannesburg. The rapid growth of the goldmining industry intensified processes started by the diamond boom: immigration, urbanization, capital investment, and labour migrancy.

The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined. Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well
In South Africa, mining for gold typically involves methods like panning, sluicing, dredging, hard rock mining and byproduct mining. The most effective method used is hard rock mining, since reserves are typically encased in deep underground rock. Where is gold found in South Africa?
A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.
Apart from gold mining, there are many other minerals being produced, for some of which South Africa is the leading producer and holder of reserves. The Green Paper also has a chapter on smallscale mining which is intended to encourage the small and medium sized operator, to the benefit of employment and the overall economy.
Gold mining takes place in countries such as South Africa, Australia, the United States, Canada, China and Pakistan. One of the largest gold mines known worldwide is the Aurora Gold Mine located in Guyana, Africa. As of the year 2013, the Aurora Gold Mine has an estimated reserve of million ounces.

With South Africas economy built on gold and diamond mining, the sector is an important foreign exchange earner, with gold accounting for more than onethird of exports. In 2009, the countrys diamond industry was the fourth largest in the world. South Africa is
#0183;#32;The South Deep gold mine, located in Gauteng Province of South Africa, is one of the worlds biggest gold mines. It is also the seventh deepest mine in the world with a depth of 2,995m below the surface. It has a mine life of 75 years. The underground gold mine also has a large resource base of uranium.
