Title: Method of separating suspension, in particular for waste water treatment, and an apparatus for performing the same
Inventor: MACKRLE SVATOPLUK
IPC: C02F1/52
Filed: 2002-05-07
Abstract: A method of separating suspension, in particular for treatment of waste wate r, wherein the flocculating suspension is separated from the liquid by filtrati on in a fluidized layer in a sludge blanket wherein the flocks are created from the separated suspension and the fluidization is maintained by the rising stream of liquid, while the liquid with suspension enters the fluidized laye r from the bottom and the liquid freed from suspension is discharged above the surface of the sludge blanket represented by the interface between the fluidized layer and the liquid without suspension. The thickened separated suspension in form of flocks from a sludge blanket is withdrawn from the zon e of the fluidized layer, the velocity of upward flow in the fluidized layer essentially decreasing in the upward direction. The apparatus for performing this method contains an upward widening separator (1) provided by inlet (5, 38, 59) of treated suspension in its bottom part, and by means for withdrawi ng the liquid without suspension at its top. A separator (1) the inner space of which contains a separation space is provided with at least one withdrawal spot of the thickened suspension from separation space that is arranged abov e the inlet (5, 38, 59) into separator (1), predominantly at its outer wall (2 ) or outer walls (33, 34, 50, 51) and under the surface of the sludge blanket.

Abstract: The invention relates to the removal of bivalent copper from copper chloride solution in connection with the hydrometallurgical production of copper. In the copper production process, a copper-bearing raw material is leached with a chloride-bearing solution. The copper chloride solution formed in the leaching, which contains both mono- and bivalent copper, undergoes bivalent copper removal at least in part by precipitation, and the copper(I) chloride solution is conduced to further treatment. Precipitation of the bivalent copper occurs as alkaline copper chloride precipitation. The alkaline copper (II) chloride formed is leached as copper(II) chloride either separately or in connection with raw material leaching, and is used in copper raw material leaching.
