The ore is often brown iron stained rock or massive white Quartz and usually contains only minute traces of gold To extract the gold the ore is crushed then the gold is separated from the ore is the presence of graphitic carbon in a gold ore This species which occurs naturally in many orebodies particularly in the SW United States and West Africa is able to re adsorb gold cyanide from the leach solution lowering overall gold recovery Finally refractoriness can be due to physical interference ie the inclusion of very fine particles of gold usually < 1 micron in diameter

Carbon Adsorption In Recovery Of Gold Mine EngineerComExtraction of gold using cyanide nzqagovtnz

The carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton If the ore is a high grade it may be feasible to tank leach it By high grade it would probably be gold ore The dissolved gold in the form of the complex now needs to be separated out and recovered This can be done by a process called absorption Absorption is when gaseous or dissolved species attach to a solid surface A substance called activated carbon is used to absorb the gold Activated carbon is formed from wood peat coal etc It is treated so that gold will absorb to its

Extracting Gold HowStuffWorksHow gold is made history used parts procedure

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 carbon in pulp As the cyanide and oxygen react chemically gold in the pulp dissolvThe carbon in pulp method also uses cyanide but utilizes carbon instead of zinc to precipitate the gold The first step is to mix the ground ore with water to form a pulp Next cyanide is added to dissolve the gold and then carbon is added to bond with the gold After the carbon particles are removed from the pulp they are placed in a hot caustic corrosive carbon solution which

During the CIL process gold is leached from the ore using an alkaline cyanide solution The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon Elution is the next step in the process whereby the adsorption of the gold cyanide complex onto carbon is reversed Loaded carbon is removed from the CIL circuit and the gold Gold is extracted from its ores by mechanical means and separated from other metals by chemical processes notably the cyanide process the amalgamation process and the chlorination process in this the ore is oxidized and chlorinated and the gold precipitated with hydrogen sulfide It also occurs in compounds notably telluride minerals
