Applications


Evonik is a leader in collectors for cationic reverse flotation for iron ore beneficiation and collectors for cationic reverse flotation for iron ore beneficiation. Our cationic collectors are used in the beneficiation of many other minerals to improve the efficiency of mines where traditional collectors alone do not function.


Iron Ore

Evonik is a leader in collectors for cationic reverse flotation for iron ore beneficiation. We produce an array of performance chemicals that have been used in hematite and magnetite mines globally. These include our high quality Tomamine® M and Arosurf® MG reagents for reverse flotation silica from iron ore that are specifically designed for this type of mineral flotation.

Iron ore mines are slowly becoming more complex:

  • Mining sweet spots are becoming limited and

  • Previously processed tailings are recycled

Hence the need of specialty chemistry to target these difficult ores. Evonik can tailor make formulations utilizing chemistries to help optimize metals recovery, level of frothing and concentrate grade.
