细粒级氧化铜矿浸出矿浆絮凝沉降试验 总被引:1,自引:1,他引:0
采用复合絮凝剂对某细粒级氧化铜浸出矿浆进行沉降试验,考察了絮凝剂种类和用量、矿浆浓度等对沉降性能的影响。结果表明,当矿浆质量浓度为8%,每吨干渣PHP-5与PHP-8用量分别为48g和12g时,矿浆沉降速度达到5.1m/h,完全满足工业要求。 相似文献

针对某铜矿超细全尾砂在絮凝沉降过程中存在底流浓度偏低和沉降速度较缓等问题,选择了适当的絮凝剂并进行参数优化,以提高絮凝沉降效果。首先,对涉及矿浆尾砂等关键试验材料进行详尽的物化分析;然后,对多个候选絮凝剂进行了比较与筛选,通过参数优化,最终确定了最为合适的絮凝剂型号。这一研究成果为突破矿浆絮凝沉降过程中的性能瓶颈提供了有力的理论和实践支持,并显著提高了絮凝沉降效能。此外,深入探究了全尾砂矿浆浓度、絮凝剂投加量以及絮凝剂溶液浓度等因素对超细尾砂絮凝沉降过程的影响。研究结果显示,超细尾砂絮凝沉降受到多个因素的交互作用影响,通过执行回归分析,得出了最佳参数配比,即全尾砂矿浆浓度为10%,絮凝剂单耗为20 g/t,絮凝剂溶液浓度为0.05%。本研究为矿山生产实践提供了有价值的指导,并为下一步的参数优化工作提供了参考。通过优化絮凝剂的选择和参数调整,可以进一步改善超细全尾砂絮凝沉降过程,提高底流浓度和沉降速度,从而提升矿生产效率。 相似文献

为解决拜什塔木铜矿因尾砂含泥量高而导致的沉降脱水效果差及膏体输送阻力大等问题,基于絮凝沉降实验确定了适用于该矿的全尾砂膏体充填参数。首先,利用拜什塔木铜矿全尾砂与不同絮凝剂开展了尾砂絮凝实验,优选了最为适合该矿的絮凝剂;然后,根据选定的絮凝剂开展了不同单耗条件下的尾砂沉降规律研究;最后,基于确定的最佳絮凝剂单耗,采用自制的深锥实验装置开展了室内动态沉降与压密取样实验。研究结果表明:絮凝剂可以明显提高全尾砂沉降效果,以沉降速度为判据,Magnafloc5250絮凝剂的絮凝效果最优,且在该絮凝剂掺量为25g·t~(-1)时其技术经济效益最佳;从动态压密、底流取样两个角度对底流浓度进行了研究,确定浓密机最佳底流浓度为70%~71%。 相似文献
