removal of limestone from bauxite by magnetic separation,in some greek mines, heavy media separation has been used to remove limestone from bauxite due to the difference in specific gravity. however this process .eriez permanent magnetic separators,used widely in the iron and coal mining industries to speed settling of fine magnetic particles in ore slurries and heavy media slurries, they are finding new use in .wet drum magnetic separators for heavy media application ,the initial intent of the wet drum magnetic separator was to simply recover the magnetite circulating in the heavy media circuit. over the years the .artificial magnetite in heavy-media separation ,magnetite, a magnetic iron oxide having a specic gravity of about 5.0, for example, can be used to prepare a fluid medium sufficiently dense to be practically .

for some time i have been trying to find a simple and rapid field method of separating the magnetic and faintly magnetic from the non-magnetic minerals in the ,heavy media separation - an overview,nowadays, magnetic field has been used as a heavy media at fineness of between 100 and 325 mesh. separation using heavy media can be done in either conventional heavy media, thanks or in heavy media cyclones.
donnely (16) describes the use of cyclones to classify the tailings from the magnetic separators prior to scavenging with a secondary magnetic separator. he also ,dense media separation (dms) plants,dense media separation widely applied in the mining process like a diamond plant, it can be separated by simple ways like magnetic separation, flotation or
