The export of raw mineral resources has been steadily rising over the past decade. In June 2011, the Department of Mineral Resources developed a beneficiation strategy for the minerals sector (1), arguing in essence that it is possible to industrialise by leveraging natural resources, with the government driving beneficiation.
The appliion of mining technology in South African gold mining has two main aims: to assist the industry and its employees to work safely and to work efficiently. A great deal of attention is currently being focused by gold mining companies on the development of processes and technologies that will remove – as far as possible – individuals from the rockface, in order to .
· Historically, mercury has been widely used in placer gold mining to form mercurygold amalgam with smaller gold particles, thereby increasing the rate of gold recovery. In the 1960s, largescale mercury use stopped. In artisanal and smallscale gold mining (ASGM), however, mercury is still used, often clandestine, gold prospecting.
The story behind gold's discovery is still disputed. Jan Gerrit Bantjes and the Struben brothers unearthed gold on separate occasions in 1884. However, according to South African History Online, these were minor reefs and credit for the discovery of the main reef on Langlaagte Farm went to Australian George Harrison in July 1886.
· Gold mining was not resumed in Puerto Rico until 1828, when a mine was once again established in the Central Highlands. The first gold deposits worked by the Spaniards were the placer gold deposits. These placer deposits are associated with the major rivers that drain north from the Central Highlands, and were the easiest deposits to mine.

Open Document 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).
· Predecessors of Clariant, Cytec and Dow were all involved in the development and sales of these pioneering chemicals in mining. Some niche chemistries have been developed as an alternative to xanthates from Cytec and others, but they are still thought to account for less than 5% of the sulphide collector market.
Development of a mining industry Most of the gold won in the 1860s was found in rich, surface gravels, and was worked by individuals or small groups using simple equipment. The richer and most accessible ground was quickly exhausted, and largerscale mining started in the 1870s.
· Nearsurface goldmining in the region likely began in the 1500s, and several artisanal goldminers continue to operate today. The techniques they employ range from basic gold panning, to open pits, to more sophistied underground operations. Goldmining in the Essequibo region dates back to the mid1800s.
· Gold and diamond mining in Liberia was carried out largely by alluvial mining of smallscale operations, with estimates of over 100,000 artisanal miners in Liberia. But nearly 14 years of war (1989–2003) destroyed much of the country's productive infrastructure and brought mining to a virtual halt.
America's first gold rush was in North Carolina. The discovery of gold in 1799 in Cabarrus County and subsequent gold mining successes in the 1820s and 1830s made the state the leading producer of gold in the until 1849 and the California gold strike (1848). The first placer mining in streams and creeks got underway in 1804.

Mining in Victoria Victoria (VIC) has played a huge part in Australian mining history and is still providing exciting potential for mineral exploration today. VIC is known for producing gold, antimony and brown coal. VIC is home to large mining companies including an innovative mining equipment and technology sector (METS). Fast facts:
1911. The first gold is discovered in the MalarticVald'Or region by Sullivan and Hertel Authier, but it is only in 1928 that the exploration results are encouraging enough for the Sullivan mine to begin operations. . The opening up of Québec's northwest determines the future of the mining industry.
· 5. Big data and mining. Data transparency to aid the mining industry's relations with stakeholders. Collecting and processing massive amounts of data will be essential for mining companies as they digitalize and automate their operations. What data should be shared and made transparent will continue to be a major area of debate.
· Between 1933 and 1941, gold was the dominant and most important mineral in the mining industry. Under the tyranny of the Japanese, Filipinos in many regions of the country were coerced into mining for metals to be used for war weapons in Japanese imperialism.
The gold mining industry has flourished since then and continues to do so. Gold mining was initially done in the same manner as mining copper, iron or other minerals. Thousands of diggers worked day and night to dig out gold, which was processed in traditional ways. Gold was smelted in the furnaces, just as iron or copper are smelted.
