Abstract
The invention provides a method for removal of metal sulphide particles from a liquid stream comprising a solvent and metal sulphide particles, using a filter system comprising at least one membrane, the method comprising contacting the liquid stream with the membrane, thereby transferring metal sulphide particles from the liquid stream onto the membrane surface to obtain a liquid stream depleted of metal sulphide particles and a filter system comprising a membrane enriched in metal sulphide particles. The invention further provides an apparatus for removal of metal sulphide particles from a liquid stream comprising a solvent and metal sulphide particles, wherein the apparatus comprises a solvent regenerator column () comprising at least one inlet and two outlets, which solvent regenerator column is connected to filter system () comprising at least one membrane and comprising at least one inlet and one outlet, which the filter system is connected to a separation column () comprising at least one inlet and two outlets.
