摘　　要：采用高能球磨对铜精矿进行活化预处理,并通过超声场辅助矿浆电解的方法直接利用铜精矿制备出平均粒度小于10μm的超细铜粉。超细铜粉经油酸和丙酮的表面改性处理后,抗氧化性能得到提高。The activation pretreatment of copper concentrate has been done by high energy ball mill,and ultrafine copper powder with average size less than 10 μm has been prepared by directly using copper concentrate and ultrasonic slurry electrolysis.The antioxidation performance of ultrafine copper powder has been improved after surface transform treatment using oleic acid and acetone.
