The scope of application of activated carbon It has a highly developed pore structure and is an excellent adsorbent. The adsorption area per gram of activated carbon is equivalent to eight tennis courts. And its adsorption is through physical adsorption and chemical adsorption. Sexual adsorption is achieved. In addition to the carbon element, its components still contain a small amount of hydrogen, nitrogen, oxygen and ash. Its structure is formed by the accumulation of six rings composed of carbon. Based on the microporous volume and high surface area of ​​activated carbon, gold adsorption activated carbon can be made from many kinds of carbonaceous substances, including wood, sawdust, coal, coke, peat, lignin, fruit stone, hard shell, sucrose Pulp, bone, lignite, petroleum residue, etc. Among them, coal and coconut shell have become the most commonly used raw materials for making activated carbon. The production of activated carbon is basically divided into two processes. The first process includes dehydration and carbonization. All the decomposable substances in it produce a developed microporous structure and a huge specific surface area, so it has a strong adsorption capacity. The adsorption capacity of activated carbon, fast adsorption, high strength, is used for gold extraction and other precious metal extraction. Activated carbon not only has a large adsorption capacity, but also fast adsorption, which can greatly improve the gold recovery rate and equipment production efficiency.
