Flotation
Evonik is a leader in 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.
Phosphate
As the global population is increases, the world needs an increasing amount of fertilizers to grow food. Phosphates are key components in fertilizers. Evonik’s high performance Tomamine® M and Arosurf® MG reagents for reverse flotation of silica from phosphate are specifically designed to provide equivalent to better recovery of phosphate and removal of silica at lower levels than competing commodity chemistries.
Potash
Evonik produces an array of performance amines for the Potash mining industry. These include our high quality Tomamine® M and Arosurf® MG reagents for the flotation of potash ores. We can tailor make formulations utilizing chemistries to help optimize recovery, level of frothing and concentrate grade.
Miscellaneous
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. A number of these are
- Zinc
- Corbonate
- Feldspar
- Glass sands
- Silica
- Barite
- Wollastonite
- Niobium
- etc.
Please reach out to Evonik with specific purification difficulties; we can tailor make formulations utilizing chemistries to help optimize metals recovery, level of frothing and concentrate grade.
