Figure 1 Experimental equipment used for co-precipitation tests (a) and reaction mixture evolution during a typical test: at the beginning (b); after the complexing agent addition (c); at the precipitation phase end (d) 2.2 Rigorous simulation model The co-precipitation process has been modelled and simulated on UniSim Design® R470 using the OLI Engine® 10.0 package suitable for electrolytic equilibria.	cache/cet-13107.pdf	txt/cet-13107.txt
