Gold extraction - Wikipedia

History. The smelting of gold began sometime around 6000 - 3000 BC. According to one source the technique began to be in use in Mesopotamia or Syria. In ancient Greece, Heraclitus wrote on the subject. According to de Lecerda and Salomons (1997) mercury was first in use for extraction at about 1000 BC, according to Meech and others (1998), mercury was used in obtaining gold until the latter ...

Characterising Energy Efficiency of Particle Sorting

Particle sorting is a separation technique used in the minerals industry to remove low grade particles prior to the energy intensive milling stages. Sorting devices utilise a range of different sensors to assess the composition of individual rocks and then eject those containing low value minerals using air, water or mechanical ejectors.

Gold mining - Wikipedia

Gold mining is the extraction of gold resources by mining. Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning. However, with the expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation.
