Abstract
A relational database (keys : ions and precipitates, attributes : reagents to be added, records : chemical species produced by adding reagents) is constructed, based on information about deposition and dissolution of precipitates which are described in the literature.
A computer-aided method for synthesizing metal separation processes by precipitation is established. Processes for separating metals in leaching solution of fly ash discharged from furnaces used for burning municipal wastes are synthesized. A feasible process is tested experimentally. The result shows that the process has ability to separate metals, cadmium, copper, manganese, lead and zinc from each other. More studies are needed, however, on the optimum operating condition.
