FIELD: chemistry.
SUBSTANCE: nanofiltration, in which valuable metal is extracted from ores or wastes through leaching using a suitable leaching agent, is used. The process requires at least two subsystems of nanofiltration. In this process, the raffinate from the metal extraction process is treated with a solvent in the first nanofiltration subsystem, after which the permeate is combined therefrom with the rich solution stream and processed in a second nanofiltration subsystem.
EFFECT: achieved benefits in terms of the number of regenerated leaching agent for the necessary raw materials is obtained, in respect of installation and size in relation to the total cost.
