Activated carbon for extracting gold is made from high-quality coconut shells in Southeast Asia through carbonization, high-temperature activation, pretreatment and refining. The product has the remarkable characteristics of developed pore structure, large specific surface area, high wear resistance, fast adsorption speed, large adsorption capacity, easy desorption and reusability, and is widely used in carbon slurry method and heap leaching method for gold extraction. Activated carbon for gold adopts special technology, activated carbon particles are shaped with high strength, and vulnerable parts such as needles, tips and corners are almost completely removed. The particle shape is full and uniform, which greatly improves the wear resistance of the product. Pre-grinding is not needed after entering the factory, and it can be used directly after washing with water. Bamboo charcoal is a porous material with a large number of micropores, a considerable specific surface area and strong adsorption, which can adsorb residual chlorine and trihalomethane in water, so bamboo charcoal is suitable for purifying river water and domestic water. Using bamboo charcoal as Wet Control under the bed of a residential room can inhibit the increase of humidity and the propagation of mold and microorganism. At the same time, bamboo charcoal can be placed under the floor to prevent bacteria and adjust humidity.
