The concept of the small-scale agitated leach unit was to design and build an agitated leach system for the small-scale mining industry, with a capacity equivalent to most small operations of around 20 to 40 ton per day. Traditionally the small-scale mining industry has used the practice of concrete tanks and static leach.
For silver a similar vat contains the calcium polysulphide. It does not require a filter, but the pipe is inserted a little higher, to allow room for sediment. Apparatus - Vats. 59. Troughs for conveying the lixivium from the leaching vats to the precipitating tubs, are not built, but hollowed out of timber.
In some cases also air-lift reactors (Pachuca tanks) are used. Tank leaching processes require fine ground ores/concentrates and are more costly to operate than in-situ, heap and vat leaching operations, therefore tank leaching is performed on materials with higher metal values. Process conditions can be carefully controlled

Chemical Leaching. Chemical leaching makes use of the chemical properties of gold to leach it from ore, concentrate, or tailings. This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost.
The Vat Leaching Process Vat leaching can be described as leaching in a bathtub inside a building. Treatment of ore is site-specific as determined by metallurgical tests. Bench scale metallurgical testing of ores for their amenability to vat leaching is similar to that for heap leaching. First, bottle-roll tests of finely ground material are run.

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. This process usually takes place inside a mill or other mining facility.

Heap leaching is widely used in modern large-scale mining operations as it produces the desired concentrates at a lower cost compared to conventional processing methods such as flotation, agitation, and vat leaching.
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 and weak ...
