Process for the treatment of dilute sulfuric acid |
| abstract |
The purpose of the invention is energy-savingnreprocessed diluted wastenhigh content sulfuric acidniron for a usable product. This is achievedncontinuous mixing with concentratednsulfuric acid at residence timenreaction mixture for 5 to 150 minutes. No coolingnthe reaction mixture is allowed to settle. Clearnsulfuric acid at a concentration of about 60%nweight is further concentrated by additionnadditional concentrated acids perna final concentration of about 80 wt. Secondarynthe second acid additionnis that they are not eliminated even after cooling or transportnferrous sulfate monohydrate crystals.nThe acid thus treated may be, for examplenuse in leaching ores and fertilizer production. |
