The invention discloses a rectifying still residue extraction method, and belongs to the field of environmental protection and the technical field of hazardous waste harmless resource utilization. The technical problem that the recovery rate of residual NMP in the current rectifying still residues is not high is solved. The method comprises the following steps: soaking the residual lignosulfonate in an NMP rectifying still, adding an organic solvent for treatment, and then rectifying to obtain NMP.

A method for extracting platinum and palladium from silver electrolytes envisages the dissolution of a starting material, the sorption extraction of platinum metals from the silver electrolyte using an anion exchange resin, and desorption with an ammonia solution. The process of the sorption extraction of platinum and palladium from a silver electrolyte solution is carried out in parallel with a process of electrorefining silver. The silver electrolyte is circulated through a fixed sorbent bed at a rate of 1-15 column volume / hour, wherein the sorbent is saturated until a set critical value for the amount of palladium in the silver electrolyte is registered. The process can be carried out in an automatic mode with the photometric measurement of the concentration of palladium, wherein the set critical value for the amount of palladium in the silver electrolyte is registered up to a value of between 0 and 200 mg / l. The result is an increase in the productivity of a process of obtaining high-purity cathodic silver by virtue of an increase in the density of the current in the electrorefining process and a widening of the range of the permissible amounts of platinum and palladium in the anodic feedstock.
