The mine adopted Changjie filter press for one-phase filtration of the gold tailings with feeding concentration 35% and the moisture content in the filter cake 10%. The cyanide in the filter cake was below 0.05mg/l meeting the national environmental emission requirements. During Beijing Olympics in 2008, all the large state-owned mines around are shut down. Only the mine using Changjie filter met the emission standards with continuous production. Moreover, the tailings filtered could be piled in station.
