Beschreibung
Zusammenfassung:	The invention relates to a processing method for sodium treatment vanadium and chromium extracting residues. The method comprises the steps that the sodium treatment vanadium and chromium extracting residues, a calcium compound and water are mixed, the hydrothermal reaction is carried out, solid-liquid separation is carried out on the mixture obtained after the hydrothermal reaction, and a liquid phase and a solid phase are obtained, wherein the sodium treatment vanadium and chromium extracting residues are residues obtained after vanadium and chromium are extracted through the sodium salt roasting of vanadium and chromium residues. The invention further provides a method for extracting vanadium and chromium through sodium salt roasting of the vanadium and chromium residues with the liquid phase as an alkaline reagent to replace part of a sodium compound. By means of the processing method for the sodium treatment vanadium and chromium extracting residues, the liquid phase containing the enriched sodium element can be well separated out. According to the method for extracting vanadium and chromium through sodium salt roasting of the vanadium and chromium residues with the liquid phase as the alkaline reagent, the cost for extracting vanadium and chromium through sodium salt roasting of the vanadium and chromium residues is reduced.
