components in the ore are unaffected by the leaching process and remain in the solid state. Consequently, the metal is separated when the solids are separated from the solution after the leaching process has been completed, and the solution that is produced is termed a pregnant solution or leach liquor.
Know MoreHeap leaching, vat leaching, or the like may specifically be practiced. The cyanide leaching liquid is applied to the pile by spraying, flooding, or via a foam of oxygen gas and cyanide liquid on top of the pile. Gold and silver are recovered from the pregnant liquor.
Know MoreAlthough air agitated leach tanks were commonly used in the industry, mechanically agitated reactors are preferred due to lower operating costs. Typical residence times in the leach section may range from 20–40 hours depending on the head-grade and nature of the ore and the number of leach reactors in series may range from 6 to 12.
Know MoreLeaching is a physico-chemical process where minerals in rock masses go through dissolution under percolating water and anion/cation exchange reactions to generate metal salts in solute/colloid phase that migrate and accumulate under hydrological forces.
Know MoreFrom Example 2.9.1, the mean heat transfer rate for the tank material = (tank) = 14 kW. The mean steam flowrate to heat the tank material is calculated by again using Equation 2.11.1: Step 4 - find the mean steam flowrate to make up for the heat losses from the tank during warm-up. From Example 2.9.1:

Know MoreIn processing gold, once it is completely dissolved the solution that is formed by that dissolved gold is called the 'PREG' or short for PREGNANT SOLUTION. In other words solution that is full of gold and is accordingly yellow in shade/colour. The solids are now considered the waste and the liquid is the concentrate. To separate the two the solids are allowed to settle in a tank …
Know MoreTank Leaching and Vat Leaching are processes wherein the ores are placed in large tanks (or vats) which contain leaching solutions. They can be used to extract metals from their ores. Thus, the leaching process offers a wide range of variations which can be used to extract specific metals from their ores.

Typical residence times in the leach section may range from 20–40 hours depending on the head-grade and nature of the ore and the number of leach reactors in series may range from 6 to 12.
Know MoreTank 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. In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction;
