A novel flotation aid for use in the flotation removal of contaminates or impurities from mineral slurries. The flotation aid is an alkali aluminate compound. The flotation aid may be incorporated into a flotation reagent system that includes a chemical collector.

A study of silica and iron recovery from the iron ore concentration tailing is presented. The residue is composed of 40.1 Fe 33.4 SiO 2 8.31 Al 2 O 3 0.08 P and 0.34 MnO.The developed process of silica and iron recovery consisted of size classification magnetic separation and removal of impurities by leaching.

It is here that flotation has proven most efficient. Wet magnetic finishers producing 63 to 64 Fe concentrates at 50-55 solids can go directly to the flotation section for silica removal down to 4 to 6 or even less. Low water requirements and positive silica removal with low iron losses makes flotation particularly attractive.

Since the beginning of iron ore flotation research in the 1930s silica removal has been studied extensively while aluminum removal has received limited attention. The reverse cationic flotation route widely used in the iron ore industry is less selective for alumina–hematite separation than for quartz–hematite separation.

beneficiation of iron ore in dry process to remove silica. Removal of Silica and Alumina as Impurities from Low-Grade Iron . Pellet Plant Beneficiation is a process which removes the gang particle like Alumina Silica from the Iron Ore. Beneficiation includes selection of effective crushing and grinding technologies wet and dry beneficiation and the control of moisture levels in material.

With the depleting reserves of high-grade iron ore in the world froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century s practice in the iron ore industry froth flotation has been established as an efficient method to remove impurities from iron ore.
