His "Bradford Ore Separator," patented 1853 and subsequently improved, was used to concentrate iron, copper and lead-zinc ores by specific gravity, but lost some of the metal as float off the concentration process.
Magnetite and Chromitite ores both iron ores use this method on a large scale to remove their impurities. Learn the process of extracting Crude Metal from Concentrated Ore. Froth Flotation Process. Another method of concentration of ores is the Froth Flotation Method. This is the process for concentration of primarily sulphide ores.
Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.
flotation cells. CPT Inc. has developed a flotation process for the production of Direct Reduction DR as well as Blast Furnace BF 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.

Vieira 2009 developed a process for the concentration of tailings from the mechanical machines flotation circuit of a large iron ore concentrator in Brazil, consisting of a mixed circuit, wet high intensity magnetic separation WHIMS followed by ionic reverse flotation. The rougher WHIMS stage yielded an iron pre-concentrate 34% Fe at ...
The role of reagents utilised in iron ores flotation is reviewed. Desprm and flotation stages should be performed at pH levels as low as possible to reduce the expenses with caustic soda.
Abstract. 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.
