Jan 07, 2010· In situ desorption experiments revealed that a large fraction of the Atrac was weakly attached to the hematite surface, as it was partially removed by flushing with water at pH 8.5 and 10. These results suggest that a separate washing unit after the flotation step could be beneficial in reducing the contamination of iron ore by flotation chemicals.

Mar 10, 2008· The properties of iron ore green pellets with varying additions of a surface-active flotation collector reagent (Atrac) were studied by small-scale balling. The compression strength and plasticity were measured with a semi-automatic measuring device and the pressure curves were saved and subjected to further mathematical treatment.

Jul 01, 2018· Iron ore flotation started with direct flotation of iron oxides using selected anionic collectors such as petroleum sulphonates, fatty acids and hydroxamates. Direct flotation route was incorporated in the industries in the 1950s in Humboldt Mine, USA (1954), Republic mines USA (1956), Groveland mine USA and Anshan Iron and Steel corporation ...

the quality of the iron products. Consequently the apatite content has to be minimized. After magnetic separation the dephosphorization is performed by froth flotation of the apatite from magnetite fines using a fatty acid type collector (ATRAC) in combination with sodium silicate. The concentrated
