Hazardous properties of APCr come from a high content of soluble salts. The most effective and economically feasible way for the removal of soluble content of APCr is water washing. The results of preliminary experiments of water washing show that the extract from water washing can be a source of salts (especially chlorides of Ca, K, and Na), but there is an optimization issue that needs to be solved for successful utilization of resource recovery potential. On the one hand, a higher total liquid-to-solid (L/S) ratio leads to more efficient removal of soluble compounds from APCr and significantly improves their environmental properties. On the other hand, it leads to higher consumption of water, higher production of wastewater, and less concentrated extract, which is not so suitable for further salts recovery. This paper summarizes the results of optimization of the water washing process from the point of view of salts recovery and the improvement of environmental properties of treated APCr. The aim is to optimize the water washing process for effective removal of soluble content and stabilization of APCr with simultaneous up-concentration of extract for further recovery of salts via minimization of water consumption.
