METHOD FOR REPROCESSING AN EMULSION FORMED DURING HYDROMETALLURGICAL RECOVERY OF A METAL.

摘要

Method for centrifugal reprocessing of a solids-containing emulsion formed during the hydrometallurgical recovery of a metal, wherein the reprocessing takes place in at least one decanter (1) forming a first lighter liquid phase (5), a second liquid phase (6) and a solids phase 7), characterised by the following steps: i) determining an actual value of the density of the first liquid phase (5); ii) comparing the actual value with a desired value for the density of the first liquid phase (5); and iii) setting the outlet pressure of the first liquid phase in dependence upon the determined actual value/desired value comparison.
