The present invention relates to a method for recovering copper oxide from a copper chloride solution of copper chloride, comprising the steps of injecting air or oxygen into a copper chloride solution,1+Ions were replaced with copper Cu2+And ammonium hydroxide solution or pure ammonia gas is added thereto to prepare a copper complex salt solution in which the basic solution of pneumoconiosis is made basic and the caustic soda is added to the basic pneumocysteine solution in an amount of about 0.2 to 0.7 times And the mixture is reacted at about 60 to 90C for about 2 to 4 hours to produce copper oxide particles, which are then filtered, washed, dehydrated, dried and packed by a conventional method. According to this method, since the copper oxide particles having a large particle size are produced, the manufacturing work is easy and a high purity copper oxide can be obtained.
