摘要:

研究针对高密度全尾砂在深锥浓密机(DCT)中的絮凝过程开展试验研究,旨在确定最佳絮凝参数,以提高高密度全尾砂的浓密效率和稳定性。通过实验室絮凝试验,探索了不同絮凝剂单耗、全尾砂料浆浓度、沉降时间等因素对尾砂絮凝浓密的影响。基于实验室试验得出的高密度全尾砂最优絮凝浓密参数,开展了DCT调试运行,且絮凝沉降结果良好,验证了实验室试验结果的正确性。研究表明,确定最优的絮凝参数能够保证高密度全尾砂深锥絮凝浓密效果,为高密度全尾砂的环保处理和资源化利用提供了有效的技术和理论支持。

Abstract:

The study focuses on optimizing flocculation parameters to enhance the thickening efficiency and stability of high-density ungraded tailings in deep cone thickeners (DCT). Laboratory flocculation tests were conducted to investigate the effects of unit consumption of different flocculants, the slurry concentration of ungraded tailings, and settling time on the thickening process. Based on the optimal parameters derived from laboratory experiments for high-density ungraded tailings, the commissioning, and operation of the DCT demonstrated excellent flocculation and sedimentation perfor-mance, validating the accuracy of the laboratory findings. The research confirms that determining optimal flocculation parameters ensures effective flocculation and thickening of high-density ungraded tailings in deep cone thickeners, providing robust technical and theoretical support for environmentally sustainable tailings management and resource-based utilization.
