PROCESS OF LIQUID-LIQUID EXTRACTION OF METALS AND GEAR FOR ITS IMPLEMENTATION Russian patent published in 1999 - IPC

FIELD: extraction of metals from heavy streams of solutions during liquid-liquid selective extraction. SUBSTANCE: employment of process and gear for its implementation makes it possible to choose what phase in disperse mixture should be in homogeneous state as another phase should be in drop-shape state, to prevent aeration of organic phase and to pump phases further under low rotation speed in order to exclude emulsification. Invention makes it feasible to extract disperse mixture out of settling tank where it is spread over its entire area. Process and gear are especially suitable to recover copper at large enterprises. EFFECT: improved efficiency of process of gear. 9 cl, 6 dwg
