Using copper sheet as raw material, ammonia leaching process preparation copper ammonia complexation solution evaporates to obtain alkali formula carbon using tiny structure one kind by secondary filter
Sour copper obtains active oxidation copper powder product through low temperature calcination, and the leaching copper raw material in the technique mainly is ammonium hydroxide, accurate overanxious institute
Membrane aperture is 2~5 microns and is difficult to carry out.CN201410240133.6 is reported to be dissolved in industrial acetic copper or copper nitrate
In pure water, powdery cocoanut active charcoal is added, with ammonium hydroxide or carbonic acid hydrogen ammonium tune pH value, and is precipitated under ultrasound condition, from anti-
Collection target product high pure and ultra-fine cupric oxide powder in product is answered, ultrafine copper oxide powder purity is up to 99%.Patent
CN102320644A is reported using copper sulphate as raw material, and using ammonium hydroxide as buffer, sodium hydroxide is precipitating reagent, reaction preparation oxidation
Copper powder.However, the above-mentioned method raw materials for preparing copper oxide are high-purity red copper wire, red copper bar, copper sheet, copper acetate, nitric acid
Copper or copper sulphate etc..
Summary of the invention
The purpose of the present invention is to provide a kind of from printing with recycling copper in useless version Kun for the method for cupric oxide powder, it is intended to
Solving the existing method raw materials for preparing copper oxide is high-purity red copper wire, red copper bar, copper sheet, copper acetate, copper nitrate or sulphur
The problem of sour copper etc..
The invention is realized in this way a method of copper is recycled from printing in useless version Kun for cupric oxide powder, the party
Method the following steps are included:
(1) by printing useless version Kun acid processing, the chromium on surface is dissolved, the useless version Kun for removing surface chromium is made；
(2) the useless version Kun for removing surface chromium is placed in ammonia solution, and is passed through air and dissolves the useless surface version Kun copper, obtain ammonia
Formula carbonic acid copper solution；Ammonia formula carbonic acid copper solution is transferred in heating kettle, 100 DEG C are to slowly warm up in 1~2h, 1h is kept the temperature, makes
Kocide SD is made in ammonia after discharging completely, the ammonia of release is absorbed through absorption plant to be recycled；Kocide SD mixed liquor is turned
Enter in settling tank through settling separated from the water, the Kocide SD that solid is dried powdered；
(3) Kocide SD is calcined at high temperature and cupric oxide powder is made.
Preferably, in step (1), the acid be mass concentration be 2~37% hydrochloric acid, 2~50% sulfuric acid and/or
2~30% nitric acid.
Preferably, in step (1), the mass ratio of the material of chromium and acid ion is 1:(2~6 in the useless version Kun).
Preferably, in step (1), the reaction temperature of the acid processing is 10~40 DEG C, the reaction time is 0.5~12h.
Preferably, in step (2), the ammonia solution be mass concentration be 2~17.8% ammonium hydrogencarbonate, 2~50%
Carbonic acid ammonia and/or 2~25% ammonium hydroxide.
Preferably, in step (2), copper in the useless version Kun, oxygen in air, ammonium ion the mass ratio of the material be 1:(1
~10): (4~20).
Preferably, in step (2), it is 10~45 DEG C that ammonia, which dissolves copper reaction temperature, and the reaction time is 4~48h.
Preferably, in step (3), calcined under the high temperature specifically: 300~800 DEG C of temperature lower calcinations 0.5~
10h。
The present invention overcomes the deficiencies of the prior art and provide a kind of use in useless version Kun from printing and recycles copper for cupric oxide powder
Method, comprising steps of dissolving the chromium on surface, chromous salts being made printing useless version Kun acid processing；The useless of surface chromium will be removed
Version Kun, which is placed in ammonia solution and is passed through air, dissolves the useless surface version Kun copper, obtains ammonia formula carbonic acid copper solution；Then in heating condition
Under release ammonia be made Kocide SD；Kocide SD obtained is calcined at high temperature is made cupric oxide powder.
Compared with the prior art the shortcomings that and deficiency, the invention has the following advantages:
(1) from the yield of useless version Kun recycling copper and obtained cupric oxide powder up to 95%, the purity of copper oxide reaches the method for the present invention
98% or more；
