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. By 1899 the gold industry attracted investment worth

South Africa has failed to address the adverse environmental and health effects of more than 130 years of gold mining in and around Johannesburg, a new report from Harvard Law School shows.
An alarming 5,906 abandoned mines across South Africa were reported by the Auditor General. Many of which are Gold Mines and specifically in the Gauteng Province of South Africa.
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.
mining district of Johannesburg, South Africa, is heavily contaminated and acidified as a result of oxidation of pyrite contained in the mine tailings dumps and has

#0183;#32;Another largely ungoverned environmental concern is the pollution caused by mining through leakage and tailings dumping. Tailings are leftover materials from mining and are often dumped in rivers causing metals contamination. Several African mines have also experienced cyanide leaks the deadly poison is used to extract gold.

Today, South Africa produces only % of the worlds gold. 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
Abstract. Mining of metals such as gold, silver and copper results in the exposure to water and air of rock ore containing sulphides. This leads to the formation of several harmful products such as sulphuric acid. If uncontrolled, the water drainage from such mines may runoff into streams or rivers or leach into groundwater thus ultimately entering
Gold mining activities in the Witwatersrand have played a pivotal role in the development and existence of Johannesburg since 1886. Mining made Johannesburg the city of gold and has since been the main driving force behind the history and the economic development of Johannesburg and South Africa as a whole (Gass, 2012).
