Process for producing stable cupric hydroxide and basic cupric salts |
| abstract |
Stable copper hydroxide is prepared by removing ferrous ion from the beginning cupric solution. The ferrous ion is oxidized to ferric ion, and the ferric ion is precipitated by raising the pH of the solution to 3-4. The utilization of phosphate ion both increases the efficiency of oxidation and simultaneously precipitates ferric ion. A second raising the pH of the purified solution precipitates highly pure copper hydroxide that can be harvested. |
