| titleOfInvention | Method for producing basic chrome sulphate with dichromiumtris (chromate) slag |
| abstract | The invention discloses a method for producing basic chrome sulphate with dichromiumtris (chromate) slag. The method for producing basic chrome sulphate with the dichromiumtris (chromate) slag comprises the following steps of completely dissolving the dichromiumtris (chromate) slag with concentrated sulfuric acid, that is, adding 1.93t sulfuric acid per ton of Cr2O3 according to a Cr2O3 content in a raw material, adding 0.37-0.42t urea per ton of Cr2O3 to prepare a 10% urea solution and a 50% sodium bichromate solution, slowly adding the prepared urea solution and the sodium bichromate solution into acid soluble dichromiumtris (chromate) slag slurry, heating the slurry to be boiled, performing continuous reaction for 2-3h, filtering the reacted slurry, and after alkalinity of liquid basic chrome sulphate is detected to be qualified, obtaining a basic chrome sulphate finish product through a spray dryer. The method takes the waste dichromiumtris (chromate) slag as a raw material, is environment-friendly, saves resources, reduces unit consumption, produces obvious economic benefits, and provides an energy-saving, environment-friendly and synergetic novel production technology. |
