| titleOfInvention | A method of using copper, cobalt in nanofiltration membrane concentration and separation-neutralization precipitation recycling copper raffinate |
| abstract | The invention belongs to technical field of wet metallurgy, more particularly to from copper raffinate synthetical recovery useful resources method, more particularly to a kind of using nanofiltration membrane concentration and separation and the neutralization precipitation technology method that recycles copper, cobalt and sulfuric acid from low cobalt copper raffinate.The copper in copper raffinate, cobalt, iron, calcium, aluminium, arsenic, magnesium retention are specially entered by concentrate using nanofiltration membrane concentration and separation technology, iron, aluminium, arsenic, calcium, magnesium addition open circuit removal while concentrate handles recycling valuable metal cobalt and copper through chemical precipitation, in raffinate；Dialyzate (sulfuric acid solution) returns to the leaching system of wet type copper smelting, achievees the purpose that useful resources recycling and purification and impurity removal in raffinate, while meeting the quality requirement leached in wet type copper smelting production with electrodeposition process to solution. |
