The copper and nickel from electroplating sludge were selectively recovered by cyclone electrowinning 

technology, and the electrowinning behaviors of Cu

2+

, Ni

2+

 and other metal ions in the process were investigated. The 

results indicate that the electrolytic copper is electrodeposited from a leaching solution with high impurities and low 

copper content by cyclone electrowinning and meets the requirements of the standard GB/T467

1997, and more than 

99% copper is recovered. After the removal of chromium, the liquor with low nickel content is applied to nickel cyclone 

electrowinning, and the product meets the requirements of the standard GB/T6516

—

1997 (Ni9990), and more than 93% 

nickel is recovered. Compared to the traditional electrowinning, the cyclone electrowinning shows the advantages of high 

selectivity of metals, high current efficiency and high purity of electrolytic product.

Pick and Select electrowing Technology System

Pick and Select Electtrowing Technology is one of Electrowing system, which can be use in deal with complex cation slution recycle. For example Cu \ Co \ Ni separete , it can short the work flowt. 

China National Building Materials Group Corporation (CNBM) was established in 1984 with approval from the State Council, and then became a Central Enterprise under direct supervision of State-owned Assets Supervision and Administration Commission of the State Council in 2003.

As one of Word TOP 500, upholding the philosophy of “Making Best Use of Resources to Serve Construction”, and vigorously carrying out such strategies as “technical innovation”, “internationalization of building materials”, and “building strength with talents”, CNBM is the largest comprehensive building materials industry group in China
