Process for extracting vanadium and chromium from chromic slag by using waste acid of titanium powder plant

The invention discloses a method for separating and extracting vanadium and chromium. The method comprises the following steps of: (1) producing chromium fine sand (Cr2O3) of which the content is over 80 percent and ferric vandate of which the content is over 20 percent from two waste materials by taking waste acid of a titanium powder plant as a leaching agent and vanadium-chromium slag (containing 2.5 to 4.5 percent of vanadium and 14 to 25 percent of chromium) as a raw material; (2) putting the vanadium-chromium slag into the waste acid to allow the chromium and the vanadium in the slag to form chromium sulfate and vanadyl sulfate which can be dissolved in water very easily, wherein the leaching time is about 6 hours; (3) adding a certain amount of steel making steel slag during leaching to fulfill the aim of generating a great deal of calcium sulfate when a great deal of calcium oxide meets the acid during filtration, and wrapping, adsorbing or and stopping 'silica gel' formed by silicon dioxide in the chromium slag by the calcium sulfate which is used as a filter medium to ensure that the filtration is performed smoothly; (4) adjusting the pH value of the filtrate to be 2.5 by using sodium hydroxide, and then adding an oxidant and oxydol to ensure that the chromium in the solution is oxidized to be hexavalent, the iron is oxidized to be trivalent, and the vanadium is oxidized to be pentavalent; (5) heating the leaching solution to the temperature of between 70 and 90 DEG C to ensure that the vanadium and the iron is combined together to generate water-fast 'ferric vandate', wherein the time for thermal precipitation is about one hour, and the vanadium residual in the solution is not more than 0.4 g / L; (6) adding sodium hydroxide into the solution of which the ferric vandate is filtered out, and fully stirring the mixture until the pH value of the solution is between 5.5 and 5.9 to ensure that the chromium in the solution is completely converted into chromium.
