Reagents in iron ores flotation ScienceDirect
01/02/2005#0183;#32;The flotation performance of certain iron ore types is enhanced with the use of ether diamines in combination with ether monoamines. Amine is partially replaced by some kind of fuel oil in some concentrators. The emulsification of the fuel oil plays a relevant role in the process. The price of fuel oil is lower than that of amine and no significant environmental impact was detected. Amine
