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.

Best regards,
