| titleOfInvention | A kind of method that hydro-thermal method preparation high stability consolidates arsenic mineral |
| abstract | The present invention relates to the methods that a kind of hydro-thermal method preparation high stability consolidates arsenic mineral, will contain high arsenic solution dearsenification and be solidified, arsenic containing solution is made to obtain harmless treatment.By the trivalent arsenic in arsenic containing solution after catalysis oxidation is pentavalent arsenic, oxidated solution can directly be stored up the present invention using the solid arsenic mineral of the heavy arsenic method of lime-hydro-thermal method synthesis high stable.It first passes through the heavy arsenic method of lime and obtains calcium arsenate, then calcium arsenate is changed into the solid arsenic mineral of high stability using hydro-thermal method, toxicity leaching meets GB5085.3-2007 (solid waste judging standard-leaching characteristic identification) regulation.Present invention process process is short, and arsenic effect of sinking is good, sink after arsenic liquid can direct emission, the solid arsenic mineral stability of synthesis is high, can stablize stockpiling under the conditions of wide ph range 2~11 and strong reducing property. |
