密地选矿厂尾矿系统生产组织优化

密地选矿厂对破碎和磨选系统进行工艺设备升级改造后，原矿处理量和铁精矿产量提高，而尾矿浓缩和输送系统仍为原流程和装备。选矿厂正常生产时，尾矿浓缩系统可以满足生产能力；选钛系统停产或浓缩机出现故障时，尾矿浓缩系统处理能力不能满足生产要求，需降低磨机处理量以保障浓缩机安全运行；尾矿输送系统一直超负荷运转，存在安全隐患。根据生产组织实际，在确保选矿系统正常生产条件下，提出局部改造尾矿制备和输送系统及优化生产组织的方案，实施后保证了企业实现产能最大、规模效益提升。

Optimization on Tailings System Production of Midi Plant

Since the crushing and grinding system of Midi Plant have been upgrades and transformed，tailings capacity and iron concentrate output had increased，while the tailings enrichment and conveying system is still the original process and equipment.When the plant in the normal condition，tailings enrichment system can meet the production capacity；Ilmenite system shutdown or the thickener was malfunctioned，tailings enrichment system processing capacity can't meet the production requirements，mill capacity will be reduced in order to ensure the safe operation of the thickener；Tailings conveying system have been overstretched，has safety hazard.According to the actual production organization，production organization method by partial transforming tailings preparation and transfer system and optimization was proposed when dressing plant in normal status，ensures the enterprise to realize largest production capacity and scale.
