Located in Songtao County, Guizhou Province, The project design capacity is 160,000 tons/a EMM, supporting 300,000 tons/a sulfuric acid and waste heat power generation. The project design capacity is 80,000tpa (Phase I) EMM, with accessory facility of 300,000tpa sulfuric acid and after-heat power generation. The design is the first to apply the processes of pulverization by vertical mill, large-tank continuous leaching, on-line residue washing with large pressure filter and large cathode   electrowinning. The project was put into operation in Oct., 2013.
