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 charcoal prone to clogging screens, causing the process is not smooth. Too coarse granularity of carbon through the lift and piping water shell activated carbon, produced by wear set 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, which will affect the uniformity of string Yan W charcoal, charcoal make different size and pulp contact time is not balanced, reduced adsorption. As a result of the extent of water pollution is worsening, diminishing drinking water quality continues to decline, causing the close attention of people around the world, well-known high-quality drinking water beneficial to human health, to achieve the quality of drinking water, you must use the advanced water treatment technology, but only a very small part due to drinking water, the city's total water supply, if the high cost of water treatment processes, improve the city's water quality and pricing of all water use shell activated carbon, then do not divided use, water use, is clearly unreasonable, it is not economical. Activated carbon drinking water and one of the means in combination with other methods can be used for purification. Its advantages are: for chloroform, pesticides, different odor, organics removal of oil effects; partially removing the bacteria, chlorine, magnesium, sediments; calcium, iron, potassium and other elements that are not useful for the removal of the body; reduced color; Cost is not. In the treatment of drinking water, under normal circumstances, the ion exchange resins can not be comparable with the shell activated carbon, reverse osmosis process is also very good ability to remove organic matter, because the cost is too high and can not be promoted. Ultrafiltration although cheaper, but only effective for the removal of organic molecules adsorbed gold shell activated carbon, the scope has been limited. Activated carbon is generally a specific method for removing an organic compound is the cheapest. Silver shell activated carbon is activated carbon to purify drinking water function best selection of high-strength core-shell as raw fruit, with a special silver refining process, is widely used in drinking fountains, water purifiers, water purification equipment and other mineral pot .
