1.电解法以金属铜为原料，溶解于浓硫酸。配成电解液组成为：含Cu52.3 g/L、H2SO4约200 g/L，电解液温度58.5℃，槽电压0.33 V，阴极电流密度1.82 A/cm²。经电解精炼，制得高纯铜粉成品。

2.将硝酸铜进行重结晶、干燥，并在800～850℃下灼烧以除去氮的氧化物。然后，把制得的氧化铜放入管式炉内的瓷皿中，并在250～300℃的条件下用氢气进行还原。用此法制得的铜呈粉红色粉末状，在较高温度(800～900℃)时，铜可黏结起来，而得到海绵状物质。

3.向硫酸铜的浓溶液中放入过量的锌棒、锌块或锌粉，通过置换反应使铜析出。当溶液褪色后，回收未起反应的锌，同时用加热到60～70℃的稀硫酸或稀盐酸浸泡含锌残渣的沉淀铜。在锌被完全溶解后，将沉淀铜转移至过滤器上，然后用稀盐酸、水洗涤，最后用乙醇洗涤，并在40～50℃的条件下将铜烘干。这一制法中也可用铁或铝来替代锌。

4.粉末状氧化铜，在管式炉中于135～150℃下通氢气还原，直至黑色氧化铜转变为玫瑰色铜粉为止。
停止加热，继续通氢气冷却，即可制得成品。若要制取在空气中相当稳定的粘结体，还原温度要控制在500～520℃

5.先将工业铜用稀硝酸（或稀硫酸）和蒸馏水洗去表面污物，然后用硝酸（或硫酸）溶解，作为电解液，采用较纯铜片作为阴极，电流密度控制在120A/m2，电解产物根据产品要求，可以经水洗、酸洗、脱水、干燥。
