处理氧化铜矿最常用的选矿方法是硫化—黄药浮选法。国内外大量研究资料表明,同时加入硫酸铵是强化氧化铜矿物硫化的一种有效手段,并获得一定的经验,但是在混合铜矿浮选实践中,使用硫酸铵有何特点,还未见详细报道。我矿某厂处理的铜矿石是氧化——硫化混合铜矿石,氧化率40～45%。为了提高氧 The most commonly used beneficiation method for the treatment of copper oxide is sulfide-xanthate flotation. A large number of domestic and foreign research data show that while adding ammonium sulfate is an effective means to strengthen the sulfidation of copper oxide minerals, and gain some experience, but in the mixed copper flotation practice, the use of ammonium sulfate, what are the characteristics, has not yet seen Detailed report. I mine a copper ore processing plant is oxidation - sulfide mixed copper ore, the oxidation rate of 40 to 45%. In order to raise oxygen
