As Tripathy explains, some types of FDMS can't separate ores smaller than 45µ – frustrating given iron ore particles can be as small as 30µ. Then there are more fundamental problems of magnetic separation. Materials like iron are perfect for FDMS, after all, but what about non-magnetic metals like aluminium, copper or zinc? An …

The relevance of the paper is that dry magnetic separation (DMS) is the main beneficiation method of magnetite ores. The lack of efficient industrial-grade machines and apparatus for separating fine-grained magnetite ores means that DMS is used mainly as a pre-concentration operation for fairly large classes. The aim of the research is to study the …
