In the mineral processing, smelting, gold leaching, lithium salt, alumina red mud and other industries, there are a lot of problems in filtration and dehydration, and most of the filtrates in these industries contain harmful substances or rare precious metal substances. In recent years, the state has increasingly demanded environmental protection and resource utilization in all walks of life, and has strongly advocated energy conservation, emission reduction, cleaner production, and green manufacturing. The requirements of environmental protection agencies for such enterprises are increasingly stringent. Most companies adopt one or more washing operations before filtering operations. The process flow is: filtration→stirring and washing→filtering→stirring and washing→filtration, resulting in the process of filtration and washing. Complex, large security risks, high investment and operating costs.
In view of the dehydration process and the current status of filtration and washing in the above industries, Changjie Filter () has developed the CJX series of washing and filtering machines. The equipment replaces the conventional two-stage or multi-stage combined washing and dewatering technology under the condition of reaching internationally advanced or better filter cake moisture content and washing index, and realizes beneficiation, smelting, gold leaching, lithium salt, alumina red mud, etc. Industry washing and filtration without short circuit integration, filter cake moisture content is low, production capacity is large, filter cake washing rate is as high as 99.9%, and washing water is greatly saved, the recovery rate of valuable resources in the filtrate is increased, and the amount of sewage treatment is reduced. Alumina, lithium salt, gold, hydrometallurgy and chemical industries have provided strong support for shortening or optimizing production processes, reducing investment and operating costs, and improving corporate economic and social benefits.
Red mud washing and filtering: Different from the existing red mud sedimentation washing and filtering process, the long Jieyi washing and filtering integrated machine achieves the completion of red mud washing and filtering. The red mud moisture content is significantly reduced to 25%, and washed into the red mud. The loss of sodium oxide is also significantly lower than 0.3%, which effectively solves the problems of traditional sedimentation methods such as lengthy procedures, complicated equipment, poor adaptability, long operation time, high procurement and operating costs.
Lithium salt washing and filtering: Changjie washing and filtering integrated machine assists in the filtration and washing of lithium salt. The water content of the filter cake is less than 15%, and the lithium content of the residue is lower than the original filtration-stirring washing-filtering process. An order of magnitude, and less water consumption, the original process also adds a filter cake drying process, using Changjie washing filter integrated machine, the drying process is canceled, shorten the process, reduce equipment investment, greatly reduce production costs.
Gold washing and filtering process: In view of the high cyanide content in gold tailings and leaching slag, Changjie washing and filtering integrated machine removes gold by removing the cyanide process and countercurrent washing process. The cyanide rate is as high as 99.99%, which ensures that the filter cake cyanide content is reduced to less than 0.05mg/l, which effectively avoids secondary pollution and directly meets the national environmental standards for gold tailings, and significantly improves the recovery rate of gold in the filtrate. .
Hydrometallurgical washing and filtering: Through efficient washing without short circuit, the content of valuable components in the residue is drastically reduced, and the multi-stage filtration—washing—refiltration—washing is shortened to one machine, which increases the yield of valuable components. At the same time, the entire operation process was shortened, which provided powerful support for owners to significantly reduce the cost of infrastructure construction, procurement, management and operation.
