| titleOfInvention | A kind of Rock coal containing alum water vapour charing pretreatment preparation V2O5Method |
| abstract | The invention patent relates to a kind of Rock coal containing alum water vapours to carbonize pretreatment preparation V 2 O 5 Method.Its technical solution is: (1) Rock coal containing alum being crushed to 150 mesh with ball mill；(2) concentrated sulfuric acid and initiator solution are added into Rock coal containing alum, stirs to obtain damp sand shape mixture；(3) damp sand shape mixture is placed in carbonization chamber, 72h is carbonized under the conditions of 180 DEG C and obtains charcoal slugging；(4) by charcoal slugging with 1:(1~2) solid-liquid mass ratio, carry out two-phase method leaching vanadium, it is spare that one section of leaching liquid enters liquid storage tank；(5) one section of leaching liquid is adjusted after pH is 2.5, places 2.5h, then Low Valent Vanadium is oxidized to pentavalent vanadium with hydrogen peroxide, then carry out resin adsorption, highly basic elution, ammonium chloride precipitation, 500 DEG C roast and etc. prepare high-purity V 2 O 5 .The present invention without ore roasting process, do not generate exhaust gas, the leaching rate of simple process, easy large-scale production, vanadium can greatly improve. |
