  • Mineralogy & Flotation: Floatability VS Selectivity Test

    17/3/2017· Mineralogy & Flotation: Floatability VS Selectivity Test Assessment. Mineralogy is the driving force behind flotation performance. A flotation batch and rate test measures this as mass pull recovery and concentrate grade. The real data from a rate test can be processed to determine the flotation kinetics of metal, mineral and gangue.

  • Influence of microwave irradiation on ilmenite flotation

    20/8/2014· Microwave improves floatability of iron containing gangue minerals. However, microwave irradiation improves ilmenite flotation recovery significantly, but it also increases the floatability of gangue minerals, and makes it more difficult to achieve a selective flotation process. 3.1.3. Collector dosage. Fig. 4 shows the effect of sodium oleate concentration on the floatability of

  • Flotation of Iron Ore: A Brief Review

    The primary gangue mineral in iron ores is quartz. In addition to quartz, iron-bearing silicates (e.g., amphiboles and pyroxenes), carbonates, clays (e.g., kaolinite), and gibbsite are also commonly present in iron ores [1,2]. Iron ore beneficiation aims to eliminate the harmful elements in iron ore concentrate, which could impose a detrimental e ect on ironmaking. Table1summarizes the

A low molecular weight polyacrylic acid was found to induce full dispersion of kaolinite particles, in the presence of calcium and magnesium ions in alkaline pulp[34]. In addition to kaolinite, gibbsite, of general chemical formula Al(OH) 3, is also a common alumina containing mineral in iron ore. Separation of gibbsite from iron oxides

    floatable gangue minerals such as talc. Although talc is present in small quantities it has a disproportionate effect by enhancing froth stability and increasing the entrainment of other gangue minerals. However, there is an indication that some of the other gangue minerals, which are normally considered to be hydrophilic, such as chromite and pyroxene, report to the concentrate as floatable
