Group Physical Science Project Topic 1: What is the Impact of Mining on South Africa and its people? GOLD Authors: Michelle Dandara, Kirsten Collins, Robyn Blench, Yumna Badrooien and Sonia Mataramvura Date of Completion: 17 February 2012 Teacher: Mr Altern Abstract Mining plays a very important role in South Africa: it is one of the driving forces behind South Africa’s booming economy and provides employment for millions of South Africans. South Africa boasts world-scale primary mining processing facilities and is a world leader of new technologies. In this research project we investigated the impact that gold mining has on South Africa and its people. We found that: • South Africa is a country that is rich in mining history with the…show more content…
The gold mines of South Africa currently account for about 12% of the world wide gold production each year. South Africa has produced nearly 30% of the world’s gold in the export market from the 1990’s onward. South Africa is still home to approximately 50% of the world’s gold reserves, despite the recent decline of gold production over the past few years. Gold mining is a very popular and big industry and provides employment for a large number of South Africa’s population. The gold industry accounts for an estimated 18% of South Africa’s gross domestic product. South Africa’s gold exports were valued at about $3.8 billion in 2005. The two deepest gold mines in the world call South Africa home. The East Rand Mine in Bloomsburg and the Tua Tua Mine in Carletonville are both as 3600 metres deep. Specialized cooling technology had to be developed to protect the mine workers because the rock is so hot at this depth in the earth. It is needless to say that South Africa is home to the largest known gold reserves in the world, which is estimated to be around 40000 tons. South Africa cradles about 45-55% of the world’s total global gold reserves and mining is perhaps the biggest and most popular industry in South Africa as the nation’s economy basically depends on gold mining.
