中文摘要:
      对刚果(金)某氧化铜钴矿进行絮凝沉降试验研究。结果表明,原矿在磨矿粒度-0.150 mm占80%、矿浆浓度10%~12%、絮凝剂用量5~10 g/t,絮凝剂浓度0.05%~0.1%的条件下,沉降速度最高可达25 m/h,底流浓度可达54%以上。对于磨矿粒度-0.150 mm占80%、酸矿比132 kg/t、初始矿浆浓度25%、常温浸出时间4 h的浸出矿浆,在矿浆浓度6%、絮凝剂用量20 g/t,絮凝剂浓度0.1%的条件下,沉降速度最高可达22 m/h,底流浓度可达47%以上。
英文摘要:
      Flocculating setting process of Cu-Co oxidized concentrate from Dr Congo was experimental studied. The results show that settling velocity and solid concentration of under-flow of raw ore slurry is 25 m/h and 54% above respectively under the conditions including granularity of -0.150 mm of 80%, slurry concentration of 10%-12%, flocculant dosage of 5-10 g/t, and flocculant concentration of 0.05%-0.1%. Settling velocity and solid concentration of under-flow of slurry leached at ambient temperature for 4 h is 22 m/h and 47% above respectively with granularity of -0.150 mm of 80%, initial solid concentration of 25% and ratio of mine to ore of 132 kg/t under the conditions including slurry concentration of 6%, flocculant dosage of 20 g/t and flocculant concentration of 0.1%.
