Leaching is the process of a solute becoming detached or extracted from its carrier substance by way of a solvent.. Leaching is a naturally occurring process which scientists have adapted for a variety of applications with a variety of methods. Specific extraction methods depend on the soluble characteristics relative to the sorbent material such as concentration, distribution, nature, and size.
In a tank leach the slurry is moved, while in a vat leach the solids remain in the vat, and solution is moved which reduce wear and tear of tanks. In tank leaching the material is ground sufficiently fine to form a slurry, which can flow under gravity or when pumped.

Sepro Leach is a chemical additive used to increase the rate of gold leaching within cyanide systems. Sepro Leach is typically used for intensive cyanide leaching of gravity concentrates but can also be used to improve leach kinetics in conventional cyanide leaching systems.
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...
A manual gravity-feed system with buckets or other vats and small growing containers may be used. The vat is attached to the bottom of the tank or container with a flexible hose, and is raised to flood the tank and lowered to drain it. The vat may be lowered and raised by hand or by means of a mechanical device.
100T/D gold tailing vat leaching line (zinc wire displacement) Vat leaching involves placing ore, usually after size reduction and classification, into vats at ambient operating conditions containing a leaching solution and allowing the valuable material to leach from the ore into solution.
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 ...
A Vat leaching plant in Mamud, Sabah, has 6 vats having measurements of 14 x 9 x 6 m using counter current flow from tank to tank. About 500 metric tonne of ore is leached per day. The ore contain 2.28% Cu, 1.9% copper oxide and 0.3% copper sulphide that is not leached in the Vat. The enriched pregnant solution contain 45 kg/m Cu and 30 kg/mº ...
Leach and RIP Pilot Plant Michelin ore was pumped to the pilot plant at a pulp density of 56% and a solids flowrate of 2 kg/hr, through a circuit that consisted of 6 stages of sulphuric acid leaching, followed by 6 stages of RIP. Pulp residence time in the leach circuit was 36 hours and in the RIP circuit, 2.3 hours.
Jan 31, 2014· Introduction to INNOVAT Continuous Vat Leaching. This video details the installation of an INNOVAT Continuous Vat Leaching plant with a basic description of the process mechanics. See more at innovat.ca.
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 ...

In metallurgical processes tank leaching is a hydrometallurgical method of extracting valuable material (usually metals) from ore.. Tank vs. vat leaching Factors. Tank leaching is usually differentiated from vat leaching on the following factors: In tank leaching the material is ground sufficiently fine to form a slurry or pulp, which can flow under gravity or when pumped.

Comsur's Comco silver heap leach at Potosi, Bolivia, showed the same recovery in both a heap and an agitated leach plant. However, the silver ore leached very slowly and residence time of up to 4 days was needed in an agitated leach plant. Although the heap leach took several months to achieve the same recovery, the economics favored the heap.
