The Hybrid Vat Leach process overcomes this problem by dividing the material into two size fractions: Coarse = -5mm, +600μm. Fine = -600μm. Once separated, these two size fractions are processed separately. The coarse material, now unencumbered by fines, reports to a leach pad or vat for leaching. The fines report to a leach tank equipped ...

cyanide leach mining", cyanide is used to extract gold from the surrounding rock. While cyanide is both effective and economical, its use and transportation present significant environmental risks. Process Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open.
The tank design should allow for efficient agitation or percolation of the leaching solution through the ore bed. Step 2: Ore Preparation: Before setting up the vat leach tank, the ore needs to be properly prepared. The ore should be crushed to a suitable size to ensure sufficient surface area for effective leaching.
