本文描述了采用湿式高强度磁选机分选中等品位铁矿石的实验室试验工作。对这种选矿方法采用哪种磁选机所需考虑的因素进行了讨论。本文还描述了一个铁矿石选矿厂的高强度磁选流程设计，包括使选矿厂的操作具有灵活性的方法，以及为高磁场强度分选室提供适宜保护的方法．本文描述了该选矿厂投产后多年生产的结果及其生产经验。本文提供了所处理的各粒级赤铁矿的回收率数据，并与文献上的数据进行了比较。对提高选厂指标的可能方法进行了讨论。
This paper describes the laboratory testing of wet grade high strength magnetic separators for the separation of medium grade iron ore. The factors to be considered for the magnetic separator of this type of dressing are discussed. This article also describes the design of a high-intensity magnetic separation process for an iron ore beneficiation plant that includes methods that provide flexibility in the operation of the concentrator and methods of providing suitable protection for high-field strength compartments. This paper describes the results of multi-year production at the concentrator and its production experience. This article provides data on the recovery rates for the various hematite fractions processed and compares them with the literature data. Possible ways to improve the mill selection criteria are discussed.
