摘要:
浮选时间是选厂设计的重要参数之一,而浮选时间的确定与实验室小型试验的浮选时间和放大系数有关。针对难选金矿浮选时间的选定问题,在某选厂原设计(1 500 t/d)的基础上,重新进行了选厂设计以及实际浮选时间和放大系数的计算,验证选厂浮选时间的放大系数。随着矿石性质的变化,在该选厂开展了浮选工艺优化试验,将试验成果应用于选厂生产中,并在磨矿细度和浮选条件相同的情况下,开展了不同矿石处理量工业试验,确定了选厂最佳矿石处理量,计算了优化后的浮选时间和放大系数。结果表明:小型试验浮选时间为21 min,选厂实际浮选时间为84.08 min,实际放大系数为4.00;相比优化前,在原矿金品位降低0.47 g/t的情况下,选厂矿石处理量增加了204 t/d,金精矿富集比降低了0.11,金回收率提高了3.22%。研究结果可为同类型矿石性质选厂的浮选工艺设计提供参考。
