Akzo Nobel Surface Chemistry - Flotation Collectors

Akzo Nobel flotation collectors are marketed under ATRAC, LILAFLOT, ARMOFLOTE, ARMEEN and ETHOMEEN trade names. Akzo Nobel flotation collectors can help improve your recovery or concentrate quality if you work with any of the following application areas:

• Apatite, Barite, Calcite, Dephosphorization
• Dolomite, Feldspar, Fluorspar
• Graphite, Iron ore, Kyanite, Magnesite
• Monazite, Potash, Pyrochlore, Quartz
• Scheelite, Silica, Soil cleaning, Wollastonite, Zinc oxides

AKZO NOBEL SURFACE CHEMISTRY

Akzo Nobel Surface Chemistry is at the forefront of the advanced colloid and surface chemistry upon which successful flotation depends. Achieving successful flotation means using the process in such a way that it will enable you to retain maximum benefit with the unique ore composition in your plant. To do this you need exactly the right flotation reagent. These products are not to be found in a catalogue or on a shelf. Instead, they must be tailor-made by two teams of experts working together. These two teams are your people, those most closely involved with the milling operation, and our people, the chemists and metallurgists who tailor flotation chemicals to suit particular and unique needs.

FLOTATION OF CALCITE

Natural calcite deposites contain various types of silicates and graphite. For applications like paper fillers the calcite has to have a low grade of abrasive silicates as well as a high brightness. Even very low amounts of graphite is detrimental to the brightness. Akzo Nobel Mining Chemicals is today the world leading supplier of flotation collectors for cleaning of calcite. In our laboratory we can fine tune our products to the very special requirements of your ore.

FLOTATION OF IRON ORE

Due to increased demand for iron ore products low in silica and phosphorus plus increased world competition, quality considerations have become more and more important. Keeping the silica and phosphorus content as low as possible has become a major objective. Our mining chemicals for dephosphorization are used by mining companies around the world. The results obtained in plant operations vary, depending on ore type and the process. Silica flotation with etheramine has been the traditional route for many years, but the use of these collectors is often linked to excessive losses of fine iron particles. By adapting the collectors structure to the specific conditions of each ore, and with the use of new type of chemical structures it has been possible to decrease the losses of iron.

FLOTATION OF PHOSPHATE/APATITE

Normally fatty acids are used as collectors for flotation. However, this type of collector is not always suitable for the treatment of complex phosphate ores when calcite and dolomite are present. These minerals tend to co-float with the phosphate giving low concentrate grades. Akzo Nobel Mining Chemicals has developed special types of collectors which are only adsorbed onto the phosphate. This is the first known collector type for phosphates which exhibit carbonate - selective properties

FLOTATION OF POTASH

Potash is the most important source of potassium in fertilisers. Flotation is one of the major methods to upgrade the potash. Akzo Nobel Mining Chemicals is a supplier to all the leading potash producers in the world. For direct flotation of potash we can deliver either standard amines produced from different types of fatty acids but also special formulations. We can also offer collectors for reverse flotation of salt from the potash.
