HiraChem is your specialist supplier of Granular Activated Carbon. 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 deÃ?Âdusted. 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.
Our Powder activated carbon is manufactured using pure pine wood which is an excellent base for manufacturing activated carbons with good adsorption power. The steam activated process is done by activating the charcoal in a rotary kiln by heating at high temperatures by steam. The activated carbon that comes out from the kiln is called unwashed activated carbon. These unwashed activated carbon has higher ash and iron content. This is reduced by washing the unwashed activated carbon with acid (HCl / H2SO4) and purified water. This results in reduction of ash content to as low as 1% and iron as low as 50 ppm. The gradation of different qualities of activated carbon is done on the basis of Methylene blue value and iodine value. The iodine value is a better test as the particle size of iodine molecule is small enough to penetrate the smallest of pores. We can relate the iodine value of activated carbon directly to its surface area because of the above fact.
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

Coconut shell charcoal is a type of charcoal produced from coconut shells. It is a popular choice for charcoal production due to its high carbon content and low ash content. Used in various applications, including cooking and grilling, as a fuel source, and as a raw material for producing activated carbon. It is valued for its clean-burning properties and its ability to produce a steady and long-lasting heat source.

To suit the requirements of water purification, modern approach is to filtering huge volumes of water contaminated with many organic and inorganic contaminants but in form of blocks along with reverse osmosis, UV irradiation, mineral addition, etc. Carbon blocks are engineered and manufactured using compression molding or extrusion for different applications such as dechlorination, bad taste and odour removal, chloramines and organic materials removal, VOC removal, heavy metal removal, etc. Carbon blocks provide effective and versatile filtration for a wide range of different applications such as sediment and chemical removal. - Manufactured from coconut shell based low ash, micro porous Activated Carbon. - Designed to be used in most standard size housings. - High adsorptive capacity & high Iron, HMR & VOC removal Capacity - Simultaneously removes chlorine, bad taste, odour and organic contaminants from water. - Provides particular filtration and high dirt capacity. Size & Diameter can be customised as per the Buyers requirements
Activated carbon has very high capacity to adsorb organics, inorganics, bad taste and odour material. Adsorption capacity is enhance by modifications such as acid washing because this modification removes the acid soluble inorganic materials from the carbon and make it more porous, efficient and useful for various liquid process applications such as waste water treatment, water purification, decolourisation process in chemical and pharmaceutical industries, food and beverage industry for many purposes such as decolourization of sugar, dechlorination, decaffeination, purification of organic compounds, etc. Some of the benefits of Acid Wash carbon include Dechlorination of water, better taste, removal of bad odors, removal of color from water, removal of organic substances, etc. Available in different mess Size as per customer requirement.
One of the main applications of granular activated carbon is the purification of water. Its function is the retention of organic contaminants and the elimination, by chemical reaction, of the free residual chlorine that remains in the water after the disinfection stage. In order to inhibit bacterial growth, the surface of the carbon is impregnated with 0.1% metallic silver to make carbon bacteriostatic using ionic silver to enable it to bind strongly with carbon surface to make it suitable to function and purify large volumes of water. - High efficiency - Negligible silver leaching - No health hazards to humans - No loss in Bacteriostatic property up to 6000 litres water - Available in Granular and block form
