The process design of gold leaching and carbon in pulp

It has been noted that a small amount of leaching takes place in CIP plants, due to the additional residence time of pulp in an environment appropriate for leaching in the CIP reactors. This additional leaching provides additional economic benefit. The CIL process The carbon in leach (CIL) process, illustrated in Figure 3 is a variation of the CIP process.

Starch becomes soluble in water when heated. The granules swell and burst, the semi crystalline structure is lost and the smaller amylose molecules start leaching out of the granule, forming a network that holds water and increasing the mixture's viscosity. This process is called starch gelatinization.
