froth flotation of iron ores

Froth Flotation of Iron Ores - sapub

02/01/2012  In the iron ore industry, froth flotation is either used as a primary method for concentrating iron ores, such as Cleveland-Cliffs’ operations in Michigan, United States, or in combination with magnetic separation, which has become a popular practice in Minnesota, United States[1]. 2. Iron Ore Flotation Routes Intensive research on iron ore flotation started in America in 1930s. A variety of ...

Froth flotation of iron ores - AMERICAN CYANAMID CO

In this respect, ordinary methods of beneficiating ores by froth flotation when applied to iron ores leave much to be desired. Ordinarily, separation of mineral values from silica-bearing gangues by froth flotation takes one of two forms. Either the mineral values are floated from the silica by the use of an anionictype reagent or reagent combination, or the silica 30 is floated from the ...

1 Froth Flotation – Fundamental Principles

1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while the particles that remain completely wetted stay ...

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. The 1886 patent was to capture this "float" using surface tension, the first of the skin-flotation process patents that was eclipsed by oil froth flotation. It is uncertain if his ...
