- Contaminant Removal Process: There are a few variety of methods followed for removing contaminants from the sand. The selection of the method mostly depends upon the type of contaminant present. The methods are gravity separation, magnetic separation and froth floatation. High specific gravity mineral particles can be removed by gravity separation method. Reichert cone concentrators or spiral separators are the general equipments used in gravity separation method. Magnetic Separation methods are used for removing magnetic mineral contaminants. Magnetic Drum separator is used for removing highly susceptible magnetic materials. As the magnetic drum separators are of low intensity they can remove only the highly susceptible magnetic contaminants and not effective for low magnetic materials. For removing low susceptible magnetic contaminants, a high intensity magnetic separator (HIMS) has to be used.
