Froth Flotation of Iron Ores - Publi ions
In the iron ore industry, flotation is either froth 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
Iron ore slimes flotation - ScienceDirect
The relevant responses in iron ore reverse ionic flotation are silica grade and iron recovery in the valuable product. The flotation performance may be controlled via the dosages of amine collector and starch depressant . Low amine dosages are desirable for this reagent is the most expensive.
Mining Flotation of Iron Ore Nouryon
The main objective of iron ore flotation is to upgrade the concentrate by removing sili es and/or phosphorus-containing minerals. The use of silica flotation has increased in recent decades.
Publi ion - FLOTATION OF LOW-GRADE IRON ORE USING MACADAMIA
The results of the reverse flotation of low-grade iron ore from a fluorspar flotation tailing indi ed that the reagent combination of 400 g/t Dodecylamine collector, 5 g/t Macadamia oil at a pH of 8.5, 35 % solids and 2.5 L/minute air flowrate with a particle size distribution of 80% passing 75 microns produced a concentrate assaying 61.60 % Fe and 2.48 % Si at a recovery of 65.21 % Fe.
