| titleOfInvention | A kind of method that zinc oxide is reclaimed in the flotation tailing from zinc sulphide |
| abstract | A kind of method that zinc oxide is reclaimed in flotation tailing from zinc sulphide, comprises the following steps：(1) high alkalinity zinc sulphide flotation tailing is concentrated into 45wt%, adds 800g/t 1200g/ citric acids, stirring reaction 10 15 minutes.(2) 3kg/t of vulcanized sodium 2 is added, then stirring reaction 5 minutes adds clear water, by concentration dilution to 30wt%.(3) 500g/t of primary octadecylamine acetate 300, stirring reaction 5 minutes are added；(4) No. 2 160g/t of oil 120 are added, stirring reaction is after 3 minutes, and now pH values of pulp is 8.5 9.5.Start inflation and scrape bubble flotation, you can obtain high-quality zinc oxide product. |
