• Iron ore slimes flotation ScienceDirect

    The relevant responses in iron ore reverse cationic 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.

Since no prior reagents have come in contact with the thoroughly washed and relatively slime free magnetic iron concentrates, the cationic reagent is fast acting and in some cases no prior conditioning ahead of the flotation cells is necessary.A frother such as Methyl Isobutyl Carbinol or Heptinol is usually necessary to give a good froth condition in the flotation circuit.

    The presence of slimes is, in general, harmful to the flotation of iron ores, affecting the selectivity and the quality of the concentrates, besides causing an increase in reagents consumption. This work describes the behavior of different iron ore types from the Iron Quadrangle, Brazil, with respect to desliming in hydrocyclones and flotation, including a study on the dispersion degree as a

  • Froth Flotation of Iron Ores sapub

    With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

    In its early days flotation promised, not only the ability to treat slime, but also a great simplicity of flowsheets attributable to the fact that all that had to be done was to grind the ore to a fine pulp and then float it. Flotation was the powerful new tool to which all refractory ores would respond.
