Extracting Gold HowStuffWorks
Leaching dissolves the gold out of the ore using a chemical solvent The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp As the cyanide and oxygen react chemically, gold in the pulp dissolves When workers introduce small carbon grains to the tank, the gold adheres to the carbonGold processing, preparation of the ore for use in various products For thousands of years the word gold has connoted something of beauty or value These images are derived from two properties of gold, its colour and its chemical stabilityThe colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms Gold processing BritannicaIn one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added The zinc causes a chemical reaction which separates the gold from the ore The gold is then removed from the solution with a filter press For the carboninpulp method, the ground ore is mixed with water before cyanide is addedHow Is Gold Extracted From Gold Ore?

Gold extraction Wikipedia
Gold extraction refers to the processes required to extract gold from its oresThis may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of Straight gravity concentration of this ore, using the flowsheet shown, would result in a mixed goldtungsten concentrate containing much sulphide which is not desirable for marketing Consequently, it is evident that other concentration processes must be incorporated in the flowsheet to produce separate marketable concentrates of tungsten and goldExtracting Tungsten from Wolframite Gold OreThe other main advantage over current recycling processes, he continued, is that this specific solution is gold selective, meaning it only dissolves gold not other base metals, like copper, nickel Sustainable technique recovers gold from ewaste cheaply
How to use Mercury to recover Gold Gold, Mining and
Gold and Mercury will combine into a substance called an amalgam, and once again the gold can be separated from the mercury by the application of heat by heating the amalgam in a retort that recovers the mercury by distilling its vapor back into metallic mercury This is a process Feb 24, 2013 was351, Depending on gold to silver ratio content of the metal, the silver in aqua regia can make it hard to dissolve the gold as the silver chloride forms a crust keeping the acids from dissolving the gold, and then also the gold can make it hard for nitric acid to get at the silver to remove the silver copper from the goldHow to separate silver from gold ore> Gold Refining Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complexIt is the most commonly used leaching process for gold extraction Production of reagents for mineral processing to recover gold, copper, zinc and silver represents Gold cyanidation Wikipedia

The process included three steps: 1) leaching of antimony from the refractory gold ore with sodium sulfide solution; 2) pressure oxidation of the leaching solution containing sodium thioantimonite The next step in the process is to separate the gold amalgam from any 'unreacted' mercury We did this by squeezing the crude amalgam through a small piece of chamois leather Shiny metallic beads of mercury oozed through the leather, leaving the gold amalgam behind We now had some gold amalgam, but the challenge was to obtain gold, not some Extracting gold from rock OpenLearn Open UniversityA major development in the world’s platinum industry took place in the early nineteen twenties when large deposits of platinum bearing ore were discovered in the Transvaal in South Africa This led to the formation in 1931 of Rustenburg Platinum Mines Limited to work these deposits, and this company remains to this day the only platinum producer in South Africa and the only major producer in Extraction and Refining of the Platinum Metals Johnson
