  • Selective recovery of manganese, lead and zinc
    Patent number: 9249478
    Abstract: This invention relates to a method for the selective recovery of manganese and zinc from brines that includes the steps of contacting a brine with an ionic liquid in order to selectively extract manganese and zinc from the brine into the ionic liquid; and treating the ionic liquid containing extracted manganese and zinc with an aqueous solution to selectively precipitate manganese, producing a manganese depleted, zinc rich ionic liquid. The method can further include the steps of treating the manganese depleted, zinc rich ionic liquid with an aqueous solution to selectively precipitate zinc.
