Vat Leaching of Finely Crushed Gold Ore

The ore, confined in a rectangular leaching vat is successively treated with an increasing concentration of leach solution, which may be added as a continuous flow or on a batch basis. Thus, maximum leaching strength first comes in contact with minimum metal concentration in the ore, and as its leaching potential diminishes, it comes in contact with increasing metal concentration in the ores ...

VAT leaching of copper oxide ore - Hydrometallurgy ...

Hi We are planning a VAT leaching for HMS rejects of copper oxide ore. We are stuck at design and would value inputs. We are planning for a 5000 tons holding capacity for the VAT and feed grade is 1% copper. Size of feed 100% passing 20 mm. Would there be any channeling effect in the VAT as we are planing to feed acid at the bottom at one point.

Day 51, Procedures to obtain gold: Vat Leaching Process ...

Vat leaching can be considered when an ore body does not have the grade or quantity to be a candidate for normal agitation leaching, and as an alternative to heap leaching. At a location where there is excessive rainfall, such as more than 120 in./yr, or even a short and intense rainy season on the order of 50 in., the solution in heap leaching can become seriously diluted.
