The technical upgrading project for Ga and Ge recovery operation of 100kt/a electrolytic Zn oxygen pressure leaching plant in Danxia Smelter
The capacity of the project is 100t/a electrolytic Zn. It was put into production in 2009 and is the first large Zn smelter to apply the sulfide concentrate direct oxygen pressure leaching process. The project is the first in China to produced sulphur products from the direct leaching residue of zinc sulfide concentrates .The China first 3.2m2 largeelectrode plate and automatic Zn stripping production line was built. The goethite iron removal process was successfully applied to enrich Ga and Ge in the solution. The overall technology has reached the international advanced level. The project won the first prize by for excellent engineering design of China Nonferrous Metals Association in 2011.
