This paper investigates the reverse flotation of iron ore in a laboratory mechanical, oscillating grid and pneumatic flotation cell. The main objectives are to investigate the recovery of coarse quartz by flotation and fine hematite by entrainment.
Iron ore flotation reagents Clariants portfolio includes a comprehensive range of collectors and frothers for iron ore flotation to remove undesirable mineral impurities. The FLOTIGAM® series includes ether amines, ether diamines and other cationic collectors for every iron ore flotation challenge.
flotation cells. CPT Inc. has developed a flotation process for the production of Direct Reduction as well as Blast Furnace grade concentrates utilising column flotation technology. This process has been adopted by several major iron ore producers and current aggregate production is approximately 50 MTPY of DR grade concentrates.
Sri Lanka is known for different kind of iron ore deposits in the Precambrian basement. Among them, hydrated iron ores are predominant in the south west region. This study
The flotation results with oleic acid and dodecylamine show better recovery of iron values in the hematitequartz mixture as well as in the naturally occurring high silica ore compared to the hematiteclay mixture and the high alumina ore respectively.
The iron content is high, but considerable amount of copper is also associated in this magnetite ore. Therefore, the direct smelling process cannot be used to extract iron from this ore. In Sri Lanka there are no iron extraction industries from iron ore. There are few companies producing iron and steel from scrap iron.
The island of Sri Lanka hosts a variety of precious mineral resources, which include rutile, quartz, feldspar, graphite, clay , gems, limestone, dolomite and mica, silica.
