Froth Flotation of Iron Ores - article.sapub.org

2012-1-2  The two anionic flotation routes developed by Hanna Mining and Cyanamid, i.e. direct anionic flotation and reverse anionic flotation routes, are also being used in the iron ore industry. The history of iron ore flotation started with direct flotation of iron oxides using anionic collectors such as petroleum sulphonate, fatty acids and hydroxamates.

Iron ore slimes flotation - ScienceDirect

This investigation addressed the processing of ultrafine tailings (slimes) from an iron ore concentrator via reverse cationic flotation to produce pellet feed fines, despite the traditional view that ultrafine particles do not float. Following size analyses, chemical and mineralogical characterisation, desliming and flotation tests were performed ...

Recovery of Iron Ore Tailings byColumn Flotation

2013-12-24  The processes of iron ore flotation being either by means of mechanical cells or columns, are fed by parti- cles whose sizes vary 10 and 150 µm, the ultrafine parti- cles (slimes) are removed by means of cyclone, for they affect the process in a negative way, and the top size is limited to values between 5% and 10% above 150 µm. A strong world demand for iron ore observed in the last years have contributed to a rise in the production ca- pacity in the operating mines, to the implementation of new mines in the traditional production sites and to the interest in proper use of materials by then considered re- fuse and not used. A few mining
