Pure carbon which is gold recovery granular activated carbon is coconut-shell-based granular activated carbons specially designed for gold recovery operations. GR was developed to be a consistent, high performance, high activity gold recovery carbon product line. The activated carbon's ability to achieve high gold loadings and the relative ease with which they can be stripped enables gold processors to obtain the highest possible yields from ores with high silver/gold ratios, carbonaceous ores and ores containing other metals that complex with cyanide; for example, copper and nickel. In Carbon in Leach (CIL), Carbon in Pulp (CIP), and Carbon in Column (CIC) circuits, it is essential that the activated carbon employed provides excellent process performance, minimal losses due to attrition, and minimal maintenance problems.

Through the years, Pure carbon has continually upgraded its manufacturing processes to ensure that it continues to provide high quality products. Steps have been added to the manufacturing process which have improved the carbon's resistance to abrasion and reduced its tendency to plug retention screens in adsorption tanks. Platelets (flatter granules which are relatively long and wide while not particularly thick) can end up oriented in such a manner that they pass through the retention screens. This results in a loss of gold-containing carbon, which directly affects percent recovery and pro stability. In order to have a product that has less tendency to plug screens with "platelets," GR is also processed through a vee-wire screen and de�­dusted. GR products are manufactured specifically for gold adsorption. As a result, the quality of the carbon is extremely consistent and tailored to gold recovery applications. GR activated carbon enable the extraction of even trace amounts of gold from every ton of ore, even when processing average or low-grade ores. Pure Carbon expertise in activated carbon application technology is a valuable resource for designing and optimizing.

Among its numerous sources, coconut shells have gained significant attention as a sustainable and efficient raw material for producing high-quality activated carbon. Coconut shell-based steam-activated Carbon is mainly used for the removal of chlorine, organic contaminants, color and odor from drinking water to make it suitable for human consumption. Being microporous in internal structure, coconut shell activated carbon is well suited for organic chemical adsorption, including volatile organic chemicals.
- One of the prominent applications of coconut shell-based activated carbon is in water treatment processes. It effectively removes impurities, organic contaminants, and heavy metals, ensuring clean and safe drinking water.
- It acts as a decolorizing agent, removing impurities and unwanted odors from edible oils, beverages, and food products finding its application in the food and beverage industry. Additionally, it is employed in the purification of sugar syrups, ensuring high-quality and clear syrup for various confectionery and beverage manufacturing processes.
- It serves as an excellent adsorbent in the production of drugs, where it eliminates unwanted impurities, colorants, and traces of heavy metals making it ideal choice in pharmaceutical industry too. The high purity and porosity of coconut shell-based activated carbon make it a preferred choice for pharmaceutical manufacturers to ensure product quality and safety.

Granular activated carbons are made from rigid raw materials, giving the necessary hardness to avoid excessive losses due to attrition and handling. They present large internal surface of pore structure, ensuring high adsorption power in specific purposes and uses. They are used in fixed or moving beds as columns where the liquid or gas passes through and gets purified. They can be used in liquid or gas phase continous adsorption process and offer unusual economy in cases where carbon regeneration is favorable. In liquid phase applications they remove colloids and organic substances that give undesirable odors, colors and taste to the products. They are efficiently used for water dechlorination in processes which require super chlorination as well as the removal of organic substances from the water. In vapor phase application they participate in the solvent recovery, adsorption of colors, purification of carbon di-oxide and catalyst support. They are also used to reduce the COD and BOD in effluent waste water.

Granular activated carbon is produced from coconut shell charcoal by the process of steam activation. The coconut shell charcoal is fed into the rotary kiln and activated by steam at high temperatures resulting in the evaporation of impurities and opening up of pores on the surface. The resultant big particles are then crushed and sieved to get the desired particle size.

Our main grades of granular activated carbon are given as under. We can customize the iodine value as well as the particle size according to your requirements

Black activated carbon is a highly porous and adsorptive material commonly produced from carbon-rich materials such as coconut shells, coal, or wood. It is widely used in water treatment, air purification, and industrial processes due to its exceptional ability to remove impurities, toxins, and odors. Activated carbon works by trapping chemicals and contaminants within its vast network of pores, making it highly effective in filtering and purifying liquids and gases.

In addition to environmental applications, it is used in food and beverage industries for decolorizing liquids, in pharmaceuticals for toxin removal, and in chemical processing for gas purification. Its versatility extends to personal care products, where it is used for detoxifying and cleansing purposes in skincare.
