reagents for iron ore flotation process

Reagents in iron ores flotation - ScienceDirect

01/02/2005  The role of reagents utilised in iron ores flotation is reviewed. Desliming and flotation stages should be performed at pH levels as low as possible to reduce the expenses with caustic soda. Ether amines are by far the mostly utilised class of collector. The degree of neutralisation of the ether amine is an important process parameter.

Froth flotation - Wikipedia

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
