Abstract: In order to solve the problem of high COD value of tailings wastewater caused by tungsten collector during production, a new environmental friendly floating tungsten collector was developed and an industrial test was carried out in a concentrator in Hunan. The tungsten concentrate obtained from the industrial test contains 40.10% WO₃, the actual recovery rate of WO₃ is 71.73%, and the WO₃ recovery rate is 3.41% higher than the annual cumulative production index of tungsten in 2016 and 2017; The tailings wastewater COD of industrial experiment is 28.39 mg/L, which is 14.53% lower than the average COD of GY as collector in 2016 and 2017. The results show that the new collector presents excellent separation performance, stable production process and green environmental protection. The industrial test can ensuring the grade and recovery rate of tungsten concentrate, at the same time, the cost of comprehensive reagent and the COD value of tailings wastewater in industrial test has been reduced. It is concluded that the application of new environmental protection collector has obvious economic benefits, will bring great significance in terms of energy-saving and emission-reduction, as well as environmental protection and clean production．
