本文描述了用湿式强磁场磁分离（WHIMS）富集中等品位铁矿石的实验室研究。讨论了影响此种分选方法所需设各类型的选择因素，描述了铁矿精选厂湿式强磁选部分流程的设计，其中包括获取操作灵活性的方法及强磁场磁选分选腔的适当保护法。介绍了过去几年的运行结果及生产现场的操作情况，同时也对选厂操作的先进经验作了介绍。列出了处理的各粒级赤铁矿的回收率数据，并和文献中的数据进行了比较．讨论了改善选厂运行情况的潜在方案。
This paper describes a laboratory study that enriches middle grade iron ore with WHIMS. This paper discusses the various types of selection factors that are required to influence this sorting method and describes the design of the wet magnetic separation process in the iron ore processing plant. The method includes the operation flexibility and the selection of strong magnetic field Proper protection law. Introduced the operation results of the past few years and the operation of the production site, and also introduced the advanced experience of plant selection. The recovery data for each grade of hematite are listed and compared with the data in the literature. Discussed potential solutions to improve plant operating conditions.
