4. VatLeaching Process Vat leaching can be described as leaching in a bathtub inside a building. In Vat leaching the ore usually after size reduction (either as a finely crushed or a coarsely ground and deslimed) is manually loaded into the vats. Vats are tanks built by bricks, cement and sand may be rectangular or circular with a partial filter floor. . Picture 1 and 2 .

Method process system and apparatus for recovering. Laboratory testing has shown that high gold and silver recoveries, as to the slimes, can be obtained 90 plus for gold and 75 plus for silver by soaking the slimes of ore that is amenable, in a lower concentration cyanide solution 1 pound,, NaCN per ton solution which is employed in the soakleach process, the slimes .

Jul 13, 2016 · Vat Leaching of Finely Crushed Gold Ore. Vat leaching is carried out in vats ranging in capacity from 30 to 1200 tons. Sand for leaching is separated from slime in cones, V boxes, classifiers, and in collecting vats filled by distributors—the overflow in each case being slime or finer portion of the ore. As a rule, leaching is a simple ...

Jun 05, 2020 · Gold vat leaching process is currently widely used in smallscale gold mines, because of a series of advantages including high recovery rate, strong adaptability to ore, low cost and simple process. The basic principle is first to leach the gold from the ore with cyanide solution containing oxygen, and then to extract the gold from the leaching solution with zinc .

Vat (or tank) leaching: The ore is mixed with cyanide solution in large tanks. Although the chances of spills are lower because the leaching process is more controlled, the resulting waste, known as tailings, is stored behind large dams (tailings impoundments) which can and do fail astrophically .

Process. Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock.

Gold Recovery Process. For gold recovery, water and a cyanide such as calcium cyanide, sodium cyanide, or potassium cyanide, are added to ore or scraps to form a slurry. The gold will leach out and mix with the cyanide into a solution. Activated carbon is then used to separate and store the gold, which is removed as the final step of the process.

With the SART plant design already underway, BQE Water was contracted by the mine owner to provide process review and commissioning services for a SART plant at an open pit gold mine operation with high copper concentrations in the heap leach. More

KCA conducted laboratory investigations on ore samples from the deposit, provided conceptual design of heap leach pads and ponds, and developed the operating philosophy. KCA also provided the design, construction, and startup of a complete gold adsorptiondesorptionrecovery plant rated at a production capacity of 300 tons per day.

Gold is dissolved by the cyanide and then removed from the vat heap or columns. It is then extracted from the pregnant leach solution by adsorption on carbon or resins. This costeffective, proven method of ore extraction provides maximum recovery for many gold ores, including low grade and some refractory ores.
