为了将溶液中悬浮胶体量减少到10ppm左右,在矿石浸出与矿浆分离后进行溶液的附加澄清往往是必要的,而这种方法与后续工序无关(直接电积、溶剂萃取、离子交换等等)。用加压砂滤法来解决这个问题时,如果适宜的高分子电解质应用于流程的前面阶段,那么砂滤的作业就能得到改善。但必须在中间工厂进行初步试验来确定所采用的参数(粒度大小、过滤速度,砂层厚度等等):这些参数取决于浸出的类型、悬浮固体的性质和所要求的滤液质量。
In order to reduce the amount of suspended colloids in the solution to about 10 ppm, additional clarification of the solution after ore leaching and pulp separation is often necessary, and this method is independent of subsequent processes (direct electrodeposition, solvent extraction, ion exchange, etc.) . When using pressurized sand filtration to solve this problem, the sand filter operation can be improved if the appropriate polymer electrolyte is used in the previous stages of the process. However, preliminary tests must be carried out in the intermediate plant to determine the parameters used (particle size, filtration rate, sand thickness, etc.): These parameters depend on the type of leaching, the nature of the suspended solids and the quality of the filtrate.
