  • surface dissolution-assisted mineral flotation: a review surface dissolution-assisted mineral flotation: a review

    Jun 01, 2019· As shown from Fig. 2a, when the mineral surface is getting exposed to the solvent ions, the cations or anions can be dissolved and transferred from the mineral surface into the pulp. Therefore, the quantity and distribution of ions on the new surface of mineral will be changed. This is the most important part of thesurface dissolutionprocess affecting the quality offlotationoutput (i.e

    Jul 25, 2019· Flotation of iron ore can thereby be achieved either by floating the iron onto the froth, where it is concentrated, or leaving it in the liquid and floating off unwanted minerals. Another common method of iron ore concentration, magnetic separation, uses magnets to shift and concentrate magnetic particles like iron, most commonly through a drum or cross belt separator

    In this work, finemagnetitewas used as a magnetic seed to enhance the separation efficiency of fine hematite from quartz during reverse micro-flotation. Gradual increases in hematite recovery and iron grade were accomplished with increasingmagnetitecontent, whereas the iron content in quartz reject decreased.

    If the pH is too high during a flotation process, the viscosity of the pulp increases, which prevents adhesion of minerals to the froth and thus affects the separation of phosphorus minerals and magnetite [25,26]. A flotation pulp pH value of 9 was most suitable, achieving the following performance: iron content of 67.11%, phosphorus content of 0.22%, and iron recovery of 90.61%
