Apparently, your vat leaching plant treats oxide copper ores, try to review the copper feed grade. If the vat leaching process received a high grade material, the solution color would be dark blue. For that reason you should review the historical information. Some copper leaching operations prepare pregnant solutions of different copper content. The idea is to have a preliminary idea

This does not mean that the ore cannot be leached, but does mean a more complex process maybe needed. Such as an ammonical leach for the copper followed by cyanide for the precious metals. This will require vat or tank leaching. An alternative is flotation, especially if the ore grades (including copper) are high enough.

Leaching involves the use of aqueous solutions containing a lixiviant which is brought into contact with a material containing a valuable metal. The lixiviant in solution may be acidic or basic in nature. The type and concentration of the lixiviant is normally controlled to allow some degree of selectivity for the metal or metals that are to be recovered. In the leaching process, oxidation

Hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their ores. Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials. Processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy, and molten salt

Vat leaching involves contacting material, which has usually undergone size reduction and classification, with leach solution in large tanks or vats. Often the vats are equipped with agitators to keep the solids in suspension in the vats and improve the solid to liquid contact. After vat leaching, the leached solids and pregnant solution are usually separated prior to further

The most important operation in hydrometallurgy is leaching of properly prepared raw material. [2] The most efficient leaching agents are acids , due to their ability to leach both base and precious metals. Generally, base metals are leached in nitric acid .[5] 6 Process Stages.

Hydrometallurgy refers to the application of aqueous solutions for metal recovery from ores, ... Percolation leaching is conducted in a series of vats containing the crushed ore through which leaching solution is pumped to gradually put the metal into solution.

10.07.2017 1) Vat Leaching: Also known as “agitated tank” leaching, the lixiviant comes into contact with the metal material in large vats or tanks, which can be stirred, enhancing the reaction kinetics. The metal containing solid, such as concentrate, ore, residue, or slag, often undergoes size reduction via crushing and grinding prior to leaching.

13.07.2016 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 process, involving a vat of well-mixed neutralized sand, ample contact with strong

Vat-Leaching 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 de-slimed) 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 shows types
