This article discusses the effect of physical and chemical modifiions of starches on the anionic and ionic flotation of silica from oxidized iron ores and magnetitetaconite concentrates, and the results of the interaction of starch, pH, and calcium ions on the flocculation, clarifiion, and filtration of iron ore slimes and magnetitetaconite tailings.
In a method for enriching oxidized ores by froth flotation, use is made, as collector, of a combination comprising : at least a first compound selected among aminolalkane products having the general formula R 1 (NH CH 2 CH 2 CH 2 )n NH 2, wherein R 1 is a saturated or unsaturated straight or branchedchain hydrocarbon group containing from 8 to 18 carbon atoms, and n is an integer ...
Beneficiation of Western Mesabi Range Oxidized Taconite. In an effort to maintain an adequate supply of iron to meet national economic and strategic needs, the Bureau of Mines, Department of the Interior, is conducting research on methods for beneficiating the oxidized taconite resources loed on the Western Mesabi Range in Minnesota, thus expanding domestic iron ore reserves.

Conventional floatation treatment has poor effects on recovering CuCo sulfideoxidized mixed ores due to the high oxidation rate and large amount of carbonaceous mud of the ores. The research results showed that the preremoval of carbonaceous mud asynchronous flotation process got a better flotation results than the conventional process.
The Mineral Diversifiion Program was created by the Minnesota Legislature in 1987, "To provide for the diversifiion of the State's mineral economy through long term support of mineral exploration, development, production, and commercialization" (Minn. State. sec. ). The projects conducted under the Mineral Diversifiion Program are managed and coordinated through the Minerals ...
The AROSURF type amines are silica flotation reagents, used primarily for upgrading magnetic concentrate and oxidized taconite ore. The ADOGEN type amines are reagents for silica, mica, feldspars, and the like silies.

Jun 15, 2018 · The results (Fig. 4A) indie that flotation with DDA is more dependent on particle size than the flotation with floatability of dolomite with DDA increases with particle size, from % to % when d 50 is increased from 14 µm to 74 µm. In turn, the variation of particle size had only a minor effect on the floatability with oleate, being larger in the finer sample (% ...
