The impact of the carbon particle CIP gold extraction process on activated carbon particle size, there are strict requirements. Theoretically, the larger the particle size of granular activated carbon, which is smaller than the surface area, the lower the activity, adsorption efficiency worse. In contrast, small particle size of the activated carbon the specific surface area is relatively large, high activity, strong adsorption capacity. Production of activated carbon granules are mostly worn down from the coarse particles of carbon. As mentioned above, this part of the active carbon having the characteristics of providers, low intensity, continues to wear in the process, it is easy to lost with the tailings. In the process, activated carbon slurry was reverse flow, this flow approach is to rely on inter-stage sieve and put charcoal equipment to achieve, size too small mesh shell activated carbon clog, causing the process is not smooth. Too coarse granularity of carbon through the mention charcoal and piping, abrasion resulting set is relatively large. Carbon in pulp adsorption to achieve good results, we must make full contact with the carbon and pulp. If the carbon particle size uneven, prone to segregation in the pulp water shell activated carbon, which will affect the uniformity of string Yan W charcoal, charcoal make different size and pulp contact time is not balanced, reduced adsorption. The industrial water treatment products bleaching Most would choose activated carbon adsorbent for treatment under different circumstances, to use various types of decolorizing charcoal, in general, bleaching effect of activated carbon products, the strongest in the water, organic weak solvent and stirred for 30 to 60 minutes the best; in addition, the product size decolorization time influential, and different manufacturers, different processing methods for producing activated carbon, bleaching effects vary greatly. (1) Activated carbon general temperature is 75-80 degrees better; (2) decolorization of the strongest in the water, using the results in a very strong solvent shell activated carbon air purifier is also good and poor results in the non-polar solvent; (3) In general, used under pH3-6 better conditions; (4) Under normal circumstances gold shell activated carbon adsorption, adding the amount of one-thousandth of three (or5); (5) decolorization time is generally 30 -60min; (6) the type of activated carbon many models, such as carbon sugar, oil, carbon, etc., to choose a suitable for your use of activated carbon. Professional recycling of waste activated carbon manufacturers analysis of the product matters in decolorization use should be noted: (1) must not be added to the activated carbon, as there is a danger of bumping in the boiling solution. (2), decolorized with charcoal to be added only after complete dissolution of the solid material, because although the colored impurities soluble in boiling solvent, but when cooled to precipitate crystals, a portion of adsorbed impurities will be crystallized, so that a colored product, so use active carbon must be completely dissolved before adding the solid material.
