PROCESSING OF IRON ORE BENEFICIATION WASTES
Abstract
Iron ore beneficiation waste is formed during wet magnetic separation (WMS) and dry magnetic separation (DMS) of pre-crushed rocks. The magnetic part of the ore is fed to agglomeration and then used in the metallurgical industry, the mineral part is delivered by hydrotransport to dumps, which are surrounded by a dam. Water drains from the dump into a channel constructed around it. The water suspension located in the channel is called the slurry part. In the dump, after drying, the waste (tailings) have a fine-grained composition. Dewatered tailings are fine sand with a fineness modulus of 0.64 - 1.7. The presence of silt clay impurities is 5 - 8% (determined by the method of B.I. Rudkovsky).
