Abstract:
1. A method for manufacturing a mixer-settler used in hydrometallurgical metal processes, where the bottom of the mixer-settler is essentially rectangular, and the mixer-settler is compiled of vertical wall structures that get into contact with a solution, of a bottom plate that is cast of concrete to be inclined in the solution flowing direction, and of a cover structure, the method comprising connecting the wall structures whereafter to the bottom plate, whereafter the cover structure on top of the wall structures, connecting the wall structures by vertical support columns to the bottom plate, fastening a plurality of horizontal support beams to the vertical support columns at regular intervals, to form a wall structure, attaching a required number of plate-like wall elements made of a chemically resistant material to the horizontal support beams inside the mixer-settler, so that they form a load-bearing structure in the spaces left between the horizontal support beams, said plate-like wall elements being connected to the plate-like element covering the bottom plate of the mixer-settler.
