May 24, 2016· Leaching plants, faced with increased tonnage, coarse (up to —3/16″ solids) feed, longer retention time, erosion, corrosion and the high cost of space, must be compact, simple and highly efficient. The engineer faced with the obvious economy of using a few large agitators compared to many smaller units must also evaluate the design factors which will prevent the settling-out of solids ...
Vat leaching. Vat leaching involves contacting material, which has usually undergone size reduction and classification, with leach solution in large vats.. Tank leaching. Stirred tank, also called agitation leaching, involves contacting material, which has usually undergone size reduction and classification, with leach solution in agitated tanks.The agitation can enhance reaction kinetics by ...
Jan 02, 2013· 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 carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to ...
The cyanide solution strength is also important in leaching gold, with the typical range of solution being in the 0.02% -0.05% NaCN. The gold particle size has a tremendous effect on the time required for dissolution in a cyanide solution. Generally, the finer the gold, the quicker it will dissolve. A 45 micron particle of gold would dissolve ...
Jun 13, 2016· Heap leaching of gold and silver ores is conducted at approximately 120 mines worldwide. Heap leaching is one of several alternative process methods for treating precious metal ores, and is selected primarily to take advantage of its low capital cost relative to other methods. Thirty-seven different heap leach operations with a total production of 198 tonnes of gold per year (6,150,000 …
Other articles where Vat leaching is discussed: gold processing: Cyanidation: …ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators. For extracting gold from low-grade ores, heap leaching is practiced. The huge heaps described above are sprayed with a dilute solution of sodium cyanide ...
Feb 18, 2019· GOLD VAT LEACHING CONSTRUCTION. Tank and vat leaching involves placing ore, usually after size reduction and classification, into large tanks or vats at ambient operating conditions containing a leaching solution and allowing the valuable material to leach from the ore into solution..
