Methods of Gold Mining The Super Pit gold mine in Australia Gold mining is the process of mining of gold or gold ores from the ground There are several techniques and processes by which gold may be extracted from the earth A rocking motion provides the water movement needed for the gravity separation of gold in placer material
Gold recognizable by its yellowish cast is one of the oldest metals used by humans As far back as the Neolithic period humans have collected gold from stream beds and the actual mining of gold can be traced as far back as 3500 B C when early Egyptians the Sumerian culture of Mesopotamia used mined gold to craft elaborate jewelry religious artifacts and utensils such as goblets
Membrane separation is a family of filtration processes in which feed water is forced through a semi permeable barrier membrane at high pressure to separate specific materials from the solution These processes classified according to membrane pore size include microfiltration MF ultrafiltration UF nanofiltration NF and reverse
Amalgamation is a concentrating process in which metallic gold or silver or an alloy of the two is mixed with mercury either in a amalgamation drum or on a amalgamation table where the precious metal bonds with the mercury to form the metal laden mercury AMALGAM and the waste barren ore pulp are caused to travel different paths to effect
A gold production plant A pdf version of this article is available in the Download section on the right hand side The industrial sectors involved with the extraction from the earth of mineral resources include Filtration Separation is at the forefront of technological advances market movements trends and breaking industry news
Parting in metallurgy the separation of gold and silver by chemical or electrochemical means Gold and silver are often extracted together from the same ores or recovered as by products from the extraction of other metals A solid mixture of the two known as bullion or doré can be parted by boiling in nitric acid The silver is dissolved as silver nitrate leaving a residue of gold that
Filtration Filtration is a separation method used to separate out pure substances in mixtures comprised of particles some of which are large enough in size to be captured with a porous material Particle size can vary considerably given the type of mixture For instance stream water is a mixture that contains naturally occurring biological organisms like bacteria viruses and protozoans

The solubility of gold in a water and cyanide solution was discovered in 1783 by Carl Wilhelm Scheele but it was not until the late 19th century that an industrial process was developed The expansion of gold mining in the Rand of South Africa began to slow down in the 1880s as the new deposits being found tended to be pyritic ore The gold could not be extracted from this compound with any
The industrial separation process that I have decided to do is gold separation Gold separation can be done in a number of ways but there is not always one way to do it but the combination of a couple of these processes to extract pure gold Gold is obtained form the lithosphere It is separated from the ore found in the lithosphere
