Efficient Coconut Shell Gold Extraction CharcoalIt is made from high-quality coconut shells and refined using physical methods and high-temperature steam activation processes. The high-efficiency coconut shell gold extraction charcoal for gold has uniform particle size, high mechanical strength, strong adsorption force, and is manufactured through special processes such as water grinding. It has the characteristics of good wear resistance and high adsorption performance, and is suitable for modern gold mining production. It is mainly used for the separation and extraction of precious metals in the gold metallurgical industry by heap leaching or carbon slurry method.
Efficient coconut shell gold extraction charcoal is a porous carbonaceous material with highly developed pore structure, making it an excellent adsorbent. The adsorption area per gram of high-efficiency coconut shell gold extraction charcoal is equivalent to eight tennis courts And its adsorption effect is achieved through physical adsorption force and chemical adsorption force In addition to the carbon element, its composition also contains small amounts of hydrogen, nitrogen, oxygen, and ash, and its structure is formed by the stacking of six rings of carbon. Due to the irregular arrangement of six ring carbon, coconut shell gold activated carbon has the characteristics of multi microporous volume and high surface area.
Efficient coconut shell gold extraction charcoal can be made from various carbonaceous materials, including wood, sawdust, coal, coke, peat, lignin, fruit kernels, hard fruit shells, sucrose pulp, bone, lignite, petroleum residue, etc. Among them, coal and coconut shell have become the most commonly used raw materials for manufacturing coconut shell gold activated carbon. The production of high-efficiency coconut shell gold extraction charcoal is basically divided into two processes. The first process includes dehydration and carbonization. The raw materials are heated, dried at a temperature of 170 to 600 ℃, and about 80% of the original organic matter is carbonized. The second process is to activate the carbonized material, which is achieved by reacting it with an activator such as water vapor and carbon. In the endothermic reaction, a mixed gas composed of CO and H2 is mainly produced, which is used to burn and heat the carbonized material to an appropriate temperature (800 to 1000 ℃) to remove all decomposable substances, thereby producing a developed microporous structure and a huge specific surface area, thus having strong adsorption capacity.
The pores of high-efficiency coconut shell gold extraction charcoal can be divided into three categories according to their pore size. Large pores: radius 1000-1000 mA. Transition pores: radius 20-1000 A. Micro pores: radius -20 A.
Coconut shell gold activated carbon made from different raw materials has different pore sizes. Coconut shell gold activated carbon made from coconut shell has the smallest pore radius. Wood based high-efficiency coconut shell gold extraction charcoal generally has the largest pore radius, which is used to adsorb larger molecules and is almost exclusively used in the liquid phase. The first type of granular coconut shell gold activated carbon used in urban water treatment is made of wood and is called charcoal. The pore size of coal coconut shell gold activated carbon is between the two.
In coal based coconut shell gold activated carbon, lignite high-efficiency coconut shell gold extraction carbon has more transition pores and larger average pore sizes than anthracite coconut shell gold activated carbon, thus effectively removing large molecular organic compounds from water.
Coconut shell gold activated carbon commonly used in water treatment may not have a large surface area, but it should have more transition pores and a larger average pore size. Some coconut shell gold activated carbon for liquid phase sold in the Japanese market has the following characteristics: specific surface area of 850 to 1000 m2/g, pore volume of 0.88 to 1.5 ml/g, and average pore radius of 40 to 50A.

Introduction to the functions of activated carbon:

Efficient coconut shell gold extraction carbon has efficient air purification function. Coconut shell gold activated carbon can create a comfortable and clean environment. Efficient coconut shell gold extraction carbon cares more about human health. Activated carbon is an invisible air filter. Efficient coconut shell gold extraction carbon combines its physical adsorption and chemical decomposition functions to decompose harmful gases such as formaldehyde, ammonia, benzene, cigarettes, oil fumes, and various odors in the air, especially carcinogenic aromatic substances. Activated carbon has strong adsorption ability and is a commonly used adsorbent, catalyst or catalyst carrier. It is easy to fully contact harmful gases in the air. Activated carbon uses its own pores to adsorb harmful gas molecules into the pores, blowing out fresh and clean air. So family partners cannot do without coconut shell gold activated carbon.
Application of Efficient Coconut Shell Gold Extraction Charcoal

Efficient coconut shell gold extraction charcoal is widely used in various aspects of industrial and agricultural production, such as alkali free deodorization (refined mercaptan removal) in the petrochemical industry, ethylene desalinated water (refined filler), catalyst carriers (palladium, platinum, rhodium, etc.), water purification, and sewage treatment; Water quality treatment and protection of power plants in the power industry; Chemical catalysts and carriers, gas purification, solvent recovery, and decolorization and refining of oils and fats in the chemical industry; Refining and decolorization of beverages, alcoholic beverages, monosodium glutamate mother liquor, and food in the food industry; Gold extraction and tailings recovery in the gold industry; Wastewater treatment, treatment of waste gas and harmful gases, and gas purification in the environmental protection industry; And related industries such as cigarette filters, moisture-proof wooden flooring, odor absorption, control of automobile gasoline evaporation pollution, preparation of various impregnating agent liquids, etc. Efficient coconut shell gold extraction charcoal will have excellent development prospects and a broad sales market in the future.
