• Gravity and magnetic separation • The JKTech Drop-Weight Test measures Selective flocculation • the apparent breakage function of the Flotation SCRUBBING Scrubbing is the process whereby clays, slimes and any potential oxidization present in or on the ore typically using water. Scrubbing conditions the ore surface for further beneficiation.

Iron ore is essential in steel making; however, high-grade ores have diminished, making low-grade ores inevitable. These low-grade iron ores need further beneficiation to upgrade the iron content. Currently, traditional physical and chemical methods are utilized and are not environmentally friendly. Bio-beneficiation techniques …
