The Method of Processing High Alkali Concentration of Sodium Tungsten Solution

The method of processing high alkali concentration of sodium tungsten solution is to use strongly alkaline anion exchange resin. When dealing with high concentration of alkali solution, we just desorb for saturated resin. The characteristic is using multiple fixed beds exchange column in series, and take series of column operations. The exchange column of A leaks after wearing and containing tungsten exchange liquid directly into column B. It continues to adsorption. Column B leaks after wearing again further to column C. Column C leaks after wearing again further to column D. It is an order of pushing downstream. When column saturated, we can desorb and regenerate of resin at the same time. The regeneration of column A connected to the downstream. It is always continuing cycle operation.
