carbon in pulp process

Carbon in pulp process. 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. Carbon in Pulp Gold CIP - JXSC Machine.

Carbon Adsorption In Recovery Of Gold - Mine Engineer.Com

The carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today, since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton. If the ore is a high grade, it may be feasible to tank leach it. By high grade, it would probably be

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.

Types of Gold Extraction Equipment - Xinhai

The method of adsor gold from cyanide leaching solution of gold-bearing pulp by using the adsorption of activated carbon is called Carbon in Pulp method, while the method of simultaneous deuteration leaching process and activated carbon adsorption process is called Carbon in Leach method. The gold in gold-containing desorption solution can be recovered by zinc replacement method or

Extracting Gold | HowStuffWorks

The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. Filtering the pulp through screens separates the gold-bearing carbon.
