Steinert’s permanent magnet wet drum separators have been beneficiating iron ore and heavy media successfully for decades. In iron ore processing, the wet drum separator separates magnetic iron ore such as magnetite from waste rock – at P80’s commonly down to 28μm. Steinert has continued to develop several aspects of the WDS. Heavy media recovery – magnetite or ferrosilicon – is near on 100% efficient. The feed mechanism and separation zone are optimised according to maximum flow principles. By introducing powerful neodymium iron boron magnets, fields of up to 7,000 Gauss can be achieved, meaning Steinert can also offer so-called medium-intensity magnetic separators (MIMS). Advanced 3D calculation software incorporating finite element analysis helps to fine tune the magnetic field. For greater throughput volumes, diameters of up to 1.2m and operating widths of up to 3.6m as well as back-to-back and parallel arrangements are possible.
