Dry or wet grinding process is adopted for grinding the iron ore fines. In dry grinding process, equipment i.e. drier, ball mill, cyclones/bag filters, hot air generator recirculation fan, air slide, bucket elevator etc. are required. In wet grinding process, equipment i.e. ball mill, cyclones, slurry pumps, thickener, filter press, etc. are ...
The present invention discloses an advantageous and effective process for the concentration of iron ores, which can be fully dry or mixed, part of the process being dry, part wet, such enhancing the process efficiency as a whole by increasing recovery of concentrators and increasing the useful life of the mines.
Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.

Wet grinding systems need dewatering units with a thickener and filter, while dry grinding systems requires pre-wetting units. Pre-wetting is usually associated with dry grinding. Pre-wetting includes addition of an adequate amount of water homogeneously into the dry-ground material to prepare pre-wetted material suitable for balling.
