SPECIAL SERIES CCASORB-1100


The bone charcoal, coconut CCASORB-1100 series is a high quality material made ​​especially for use in high recovery processes of gold, silver and other high value on the market, its high hardness and excellent adsorption, they this material coal more efficiently than others in the market.

Due to its characteristics and properties, is used for leaching, this process of dilution of gold using a variety of solvents and oxidizing agents, according to the type of solvent leaching system can be classified as alkaline, neutral and acid.

The leaching of gold can be done using a variety of solutions diluted cyanide such as NaCN, Ca (CN) 2 and NH4.CN.

In the solution of gold cyanide solutions, the presence of oxygen is critical, the amount of oxygen used in plant vary between 0 and 9 mg / L. If this concentration is almost zero, it is necessary to add a substance such as oxide depolarized sodium, barium oxide, lead oxide, hydrogen peroxide, etc..

The dissolution of gold in alkaline solution takes place at ambient temperature and pressure, if pressurized the process raises the dilution capacity of the cyanide and the reaction rate, except that the process may be unprofitable because of its high cost.

The dissolution of gold in thiosulfate solutions as bromocianuro neutral, are slower and require oxygen and high temperature, so it is only used at the laboratory.

The dilution of gold in acid solutions is the most used, gold is oxidized to Au (III) and complexed with bromide, chlorine or iodine, thiourea is a reagent that forms the cationic gold Au (I), fast reaction rate and low toxicity, make this very attractive reagents for use at industrial level.

For gold recovery by leaching, the gold metal is placed in solution in ionic form, which must be removed through any method that is economically convenient and efficient metallurgically.

The gold recovery methods used are gold precipitation with zinc dust, known as the Merrill-Crowe process.

Other processes for recovering gold from cyanide solutions, including ion exchange resins through basic or resin in pulp and solvent extraction by amines.

Currently, the gold adsorption process with activated carbon is the most used for its simplicity and high efficiency.

Process innovations where deals are carbon column (CIC), carbon in pulp (CIP) and carbon in leach (CIL).

The removal or desorption of gold from activated carbon is mainly done through the process developed by Zadra, and in smaller scale through the process of the Anglo Research Laboratory (AARLA).

Generally the process of dilution of gold cyanide solutions is carried out under conditions of pressure and temperature, high efficiency and profitability of this process, now make it the most widely used to obtain gold by activated carbon adsorption, and that having this precious mineral betas with low concentrations of gold, is capable of obtaining profitable for its high efficiency.
