摘要
本文针对东山选矿厂的矿石性质和工艺流程存在的问题,进行了流程改造和优化研究。若按试验研究推荐的放粗入选粒度、增加精选、提高扫选场强的最佳方案进行改造,预计年经济效益可达300万元,且改造的投资当年即可收回。
To counter the property of the crude ore and the problems in ore dressing process flow in Dongshan Dressing Plant, the optimization research on reconstruction of the ore dressing process flow is conducted in the paper. If the process flow is reconstructed in light of the optimum scheme recommended by the experimental research, with rougher run ore particle size, higher magnetic field strength of scavengers and additional cleaners, the anticipated annual economic gains will be increased by 3,000,000 RMB Yuan and the capital cost for reconstruction can be returned the same year it is completed.
