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.

quot;Mininginduced displacement was one of the most underreported causes of displacement in Africa, and one that was likely to increase, as mineral extraction remained a key economic driver in the whole region,quot; was one of the conclusions of a official report by SADC, the Southern African Development Community, early 2006.
Small to medium scale mining equipment for the recovery of gold, chrome, tin, tantalite and more. We are based in South Africa, but our mineral processing plants are supplied globally.
Over 50% of all gold reserves are found in South Africa, with the Witwatersrand Basin remaining the largest gold resource in the world.. In 1975, South Africa was responsible for producing 40% of the gold ever mined. By 2010, however, China affirmed its status as the worlds largest gold producer with production of 324 tonnes of gold, followed by Australia ( tonnes), and South Africa
African Rainbow Minerals (ARM) Everything from coal to iron ore, gold, diamonds, cobalt, copper, oil and platinum is mined in Africa. The region has seen a sharp uptick in capital intensive mining industries, with oil and natural gas exploration taking off in the 21st century.
Gold miners too take special care to make the impact of mining for gold as light as possible. Reclaiming land to its previous natural state is the final and perhaps most important step to ensuring the process of obtaining gold doesnt result in permanent damage to the landscape.

The Mining Process. 1. Mining open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. This process removes 93% of the gold and 70% of the silver.
#0183;#32;Africas mineral industry is highly characterized by artisanal and small scale mining (ASM) operations. This is so in areas producing gold, diamonds and precious/semiprecious stones. Specific industrial minerals like cobalt, tantalum, tungsten and tin are also majorly sourced through artisanal and smallscale mining in Africa.
The Mining industry of Ghana accounts for 5% of the country''s GDP and minerals make up 37% of total exports, of which gold contributes over 90% of the total mineral exports. Thus, the main focus of Ghana''s mining and minerals development industry remains focused on gold. Ghana is Africa''s largest gold producer, producing t in 2008.
