Activated Carbon for Gold and Metal Recovery

Gold activated carbon, activated carbon types, gold extraction activated carbon has three categories: coconut shell gold activated charcoal, apricot shell gold activated carbon, wooden columnar gold activated carbon. There are several advantages in adsorbing gold: gold-specific activated carbon has uniform particle size, strong adsorption, high wear resistance, etc. It is suitable for modern gold mining production, mainly used for heap leaching or carbon slurry extraction of precious metals in the gold metallurgical industry. Benefits: 1. Improved gold recovery: Maximizes the amount of gold recovered in the leaching process. 2. Cost reduction: Reduces costs associated with the purchase and disposal of new absorbent materials. 3. Reduced environmental impact: Contributes to lower environmental impact by using sustainable materials and offering activated carbon reactivation options. Kelin granular activated carbon specifically designed for the recovery of gold and silver cyanides in gold and silver recovery circuits. It is manufactured from coconut shell, a raw material with which the maximum hardness available on the market is obtained. This is essential because it minimizes the erosion of the carbon, thus avoiding valuable losses of the adsorbed product.

Activated Carbon for Wastewater Treatment

Activated carbon is made by activating carbon-containing materials such as wood, coal, and fruit shells under high temperature and anoxic conditions. It has a large number of micropores and a huge specific surface area. Usually, the surface area of 1 gram of activated carbon is 500 to 1500 square meters, so it has a strong physical adsorption capacity and can effectively adsorb organic pollutants in wastewater. In addition, during the activation process, some oxygen-containing functional groups are formed on the non-crystalline parts of the surface of activated carbon, such as carboxyl (―COOH), hydroxyl (―OH), and carbonyl [88-01]. These groups give activated carbon the properties of chemical adsorption and catalytic oxidation and reduction, and can effectively remove some metal ions in wastewater. The wastewater activated carbon treatment method uses the physical adsorption, chemical adsorption, oxidation, catalytic oxidation and reduction properties of activated carbon to remove various pollutants in wastewater. It is a type of wastewater adsorption treatment method. Activated carbon has a large number of micropores and a huge specific surface area, and has a strong physical adsorption capacity, which can effectively adsorb organic pollutants in wastewater. Activated carbon for wastewater treatment can be divided into powdered carbon and granular carbon....

Activated Carbon for Mercaptan Removal

Colin is an activated carbon product designed for a variety of applications in the oil and gas processing industry. It is a low density activated carbon used as a catalyst support in mercaptan oxidation. The Colin product range includes granular activated carbon and pellet activated carbon for direct adsorption or as a catalyst, providing a diverse range of options for a variety of refinery tasks. The mercaptan oxidation process is an efficient and economical catalytic process for the chemical treatment of liquefied petroleum gas (or LPG) and condensate to remove sulfur in the form of mercaptans. The process relies on a special catalyst that accelerates the oxidation of mercaptans to disulfides at near economical product operating temperatures. Activated carbon is an ideal substrate for impregnation of any oxidation catalyst that removes mercaptans from LPG, propane, butane, light naphtha, kerosene and jet fuel by converting them into liquid hydrocarbon disulfides.
