BENEFICIATION PROCESS FOR IRON ORE FINES USING NOVEL REAGENTS

摘要

The present invention relates to a process to beneficiate high silica and/or alumina and/or aluminosilicate iron ore fines, comprising a two stage pre-concentration of iron ore slurry in a pre-concentration unit to separate coarser iron ore particles from ultra fine feed iron ore slurry and collecting the underflow; flotation of the underflow in a flotation cell using selective collecting agents and collecting the concentrate for further use.
