Jul 03, 2015· How the Extraction Process Works. Cyanidation is not used to extract large size gold nuggets from ore because the process is deemed too slow and is not cost effective. In mining operations that contain larger, freemilling type gold deposits, stamping and traditional gravity separation methods are more effective.

Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.

A stamp mill consists of a set of heavy steel (ironshod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam.

ball milling and gravity concentration subprocess, large ore fragments are crushed into small fragments measuring 2–3 cm in diameter. The milling process produces gold particles. In the third subprocess, cyanide is dissolved in sacks of tailings (about 40 kg of cyanide for mixing in 200 sacks of tailings).

VALVES FOR GOLD LEACHING IN CIL, CIP OR CIC CIRCUITS Process overview The nature and chemistry of an ore deposit determine the processing method used in gold production. For freemilling types of ores, this processing might only require comminution, followed by gravity concentration techniques, such as jigging or tabling. For more demanding ore

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carboninleach. This is a gold extraction process called cyanidation where carbon is added to ...

The fine ore is ground in a conventional rod and ball mill circuit. Gold is recovered by gravity separation prior to cyanidation. Cyanide bearing process water, lime and lead nitrate is added at the rod mill. The grinding thickener underflow is pumped to the cyanidation circuit where cyanide and lime are stage added, as required.

Introduction to Gold and Silver Leaching. The cyanide leaching process is the most important method ever developed for extracting gold from its ores. The early development of the process is attributed to a Scotchman, John Stewart Mac Arthur, in collaboration with the Forrest brothers. The method was introduced into South Africa in 1890.
