Carbon in Pulp Mining Equipment Manufacturer

Gold Carbon-in-pulp (CIP) production is the sequential leach, then absorption of gold from ore. During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution. CIP process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content.

The process design of gold leaching and carbon in pulp

The process design of gold leaching and carbon in pulp

Before leaching the pH of the pulp is normally adjusted to a value of around 9.5–11 to ensure minimum loss of cyanide as hydrogen cyanide. The leaching of gold can be conveniently represented by the Elsener equation: [1] Although air agitated leach tanks were commonly used in the industry, mechanically agitated reactors are preferred due

leaching and adsorption of gold from the pulp

leaching and adsorption of gold from the pulp

In most cases leaching process is done using sodium cyanide due to its high activity while in adsorption the activated carbons work well when there are many calcium ions in the pulp therefore in other words it seems like not necessary using sodium cyanide for leaching instead calcium cyanide could be used and favours adsorption of gold as well as leaching, so why this is not done in many cip or cil plants?
