3. Carbon-In-Leach (CIL): The carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation. Leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution.

Hydrometallurgy - Wikipedia

Hydrometallurgy is a method for obtaining metals from their ores. ... The five basic leaching reactor configurations are in-situ, heap, vat, tank and autoclave. In-situ leaching. In-situ leaching is also called "solution mining." The process initially involves drilling of holes into the ore deposit.

Tank leaching - Wikipedia

Tank 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;

Tank leaching - BioMineWiki - Skellefteå

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
