Flotation of Iron Ore: A Brief Review - MDPI

This is why reverse anionic flotation of iron ore using oleic acid or its soaps is usually performed in a strongly alkaline environment (i.e., above pH 11). Fuerstenau and Cummins [28] concluded that, when oleate was used as collector, the suitable pH value was between 11 and 12 in the flotation of quartz. Table 2. Equilibrium constants for oleate species in aqueous solution [29] (total ionic ...

Reagents in iron ores flotation - ScienceDirect

2005-02-01  The flotation performance of certain iron ore types is enhanced with the use of ether di-amines in combination with ether mono-amines. 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 ...
