Abstract: PURPOSE:To convert a metal, especially all dissolved copper into red cuprous oxide by aging treatment at low temperature under normal pressure by adding an aqueous solution of metallic salt and a solution of alkali containing a complex forming agent, respectively, to different permeable membrane chambers and reacting the two kinds of the solutions outside the permeable membrane chambers. CONSTITUTION:A complex forming agent such as NaCl is previously added to a reaction tank and dissolved. Then, an aqueous solution of cuprous chloride containing NaCl is added to one of permeable membrane chambers in the reaction tank charged with NaCl and a solution of alkali containing NaCl is added to the other. Then both the solutions are diffused to the outside of the permeable membrane chambers and continuously reacted to form cuprous chloride having high uniformity. In the reaction, a reaction zone outside the permeable membrane chambers has preferably pH 8-12 and the temperature is preferably 35-45 deg.C. Then, the reaction solution is successively aged preferably at 85-99 deg.C for 3-6 hours so that the whole dissolved copper is converted into cuprous chloride and production cost is extremely reduced.
