Abstract
The invention discloses a method for preparing 6N-Cu by an electrolysis technology. The method comprises the following steps of 1, preparing a raw material selected from 4N electrolytic copper, 2, punching a hole in the 4N electrolytic copper according to electrolytic cell specification for installation and suspension, 3, removing dirt on the 4N electrolytic copper, carrying out pickling immersion by a sulfuric acid solution having a concentration of 5% for more than 24h, 4, cleaning the 4N electrolytic copper subjected to pickling immersion by tap water, washing the 4N electrolytic copper by ionized water and hanging the 4N electrolytic copper by a red copper hook cleaned by ionized water, and 5, putting the 4N electrolytic copper into an anode bag made of a filter cloth soaked by ionized water and hanging the anode bag in an electrolytic cell. The method has simple processes, is convenient for operation, has good purification effects, is environmentally friendly and is convenient for popularization.
Description
Technical field
The invention belongs to electrolysis tech field, say more specifically and utilize electroplating principle to reach the object of purifying metals.What the present invention adopted is sulfate liquor, reaches a kind of method of preparation superelevation fine copper, relates in particular to a kind of method of preparing 6N-Cu with electrolysis process.
Background technology
At present, conventional refining superelevation fine copper, is divided into nitrate solution and sulfate liquor, nitrate solution, and due to the volatility of nitric acid, environmental pollution is too large, also has current efficiency low, and acid mist is large, and therefore we do not adopt.Also have a kind of employing re-electrolysis to reach purification object, this process costs is high, and energy consumption is high, complicated operation.Nonvolatile sulfate liquor that has that we adopt is purified, and in this solution, sulfuric acid itself is non-volatile, and because current efficiency is high, electrolysis acid fog does not have substantially again.Be a kind of a kind of method that substantially there is no environmental pollution thus, and refining effect is also fine, once electrolytic just can reach 6N-Cu requirement.
Summary of the invention
It is simple that technical problem to be solved by this invention is to provide a kind of technique, easy to operate, and refining effect is good, environmental protection and be convenient to popularize prepare the method for 6N-Cu with electrolysis process.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of method of preparing 6N-Cu with electrolysis process, is characterized in that: described in prepare 6N-Cu method in turn include the following steps:
The first step, prepares raw material, described raw material choose 4N electrolytic copper;
Second step, according to electrolyzer specification, by 4N electrolytic copper, punching dress is hung and is used;
The 3rd step, soaks pickling after the scrubbing of 4N electrolytic copper, adopts 5% sulphuric acid soln to soak, and the time is greater than 24h;
The 4th step, cleans with ionized water after the first tap water of electrolytic copper after pickling is soaked cleans again, then adopts the red copper hook dress that ion was washed to hang;
The 5th step, puts into by electrolytic copper the anode that the filter cloth after ionized water soaks is made, and hangs in electrolyzer;
The 6th step, start energising, cathode current density 2～3A/dm
2; Anodic current density 2A/dm
2; On time is fixed according to deposit thickness, and when thickness reaches groove, machine is not related to, limit discharging limit blanking, and the purification copper after discharging peels on titanium plate, puts into acid and soaks;
The 7th step, after soaking in acid, purification copper material is added after ionized water cleans and is used immediately hot blast drying dry by tap water, or ion washing laggard enter in alcohol then cold wind dry up.
Compared with prior art, beneficial effect of the present invention is:
Preparation method's technique of the present invention is simple, easy to operate, and refining effect is good, environmental protection and be convenient to popularize.
