Supergravity extraction process for copper hydrometallurgy process

The invention discloses a supergravity extraction process for a wet copper smelting process. The supergravity extraction process comprises the following steps: conveying raw materials; feeding of materials; performing extraction; performing cyclic extraction; standing and separating liquid; a reverse extraction oil phase is obtained; conveying raw materials; reverse extraction; circulating back extraction; and after standing, liquid separation is conducted, the wet-process copper smelting electrolyte is obtained, and the extraction and reverse extraction processes are completed. The supergravity device used in the invention greatly increases the phase interface area in the liquid-liquid heterogeneous mixing process, accelerates the updating speed of the phase interface, and strengthens the mass transfer process of the liquid phase and the liquid phase; meanwhile, according to the extraction process, the traditional extraction process is simplified, the retention time of the fluid is greatly shortened, the two
