Reduction and Precipitating of Copper from its salt solutions without using electricity  

+++

I am trying to reduce metallic copper from cupric solutions and have tried different reducing agents such as Sulfoxylates, sodium borohydride, Sodium hydrosulphite and THPC but I am looking for more reducing agents because none of these could fulfill my necessities. It must reduce copper at room temperature and in a non toxic environment with high efficiency and the precipitated particles must be very fine. I would be very grateful if you could give me some pieces of information according to your experience and researches.

to have a fine copper powder you can use Zn,Al ,or H2.in case you are looking for a ultrofine copper why not to try colloidal copper and to destroy the colloid afterwards. for detailed information contact again and i'll submit procedure. good luck

Dear Sir

I saw a response from Cair Shishani; I would also like to get a procedure for reducing and precipitating copper from its salt solutions without using electricity. He mentioned the use of Zn, Al, H2 and colloidal copper. I am interested in the use of colloidal copper and and hydrogen. I will apprecaite if I can get this information urgently.
