Excessive TiO2 in titanomagnetite concentrates (TC) causes unavoidable problems subsequent smelting. At present, this issue cannot be addressed using traditional mineral processing technology. Herein, a strategy of metallurgy-beneficiation combination to decrease the grade TC before smelting was proposed. Roasting with calcium carbonate (CaCO3) together magnetic separation proved viable strateg...

kuh-e-faryadoon and kouli kosh iron deposits are hosted by regional metamorphic rocks of sanandaj-sirjan zone around deh-bid area. plugs and domes of acid rocks protrude these metamorphic rocks. a mylonitization event is super imposed on acid rock and metamorphic complexes. field, petrological and geochemical studies have shown that (1) iron mineralization have occurred during mylonitization in...

The magnetic susceptibility measured in an alternating field is made up of in-phase and out-of-phase components. Anisotropy Magnetic Susceptibility (ipAMS) measures the bulk response all minerals a sample; however, AMS (opAMS) sensitive to only select ferromagnetic such as hematite, titanomagnetite, ultrafine magnetite. opAMS can be harnessed tool for direct determination subfabrics defined by ...

Abstract The Pyrometallurgy Division at Mintek is known internationally for the development of applications direct current (DC) arc furnace technology in smelting applications, more specifically primary resources, i.e., chromite, ilmenite, titanomagnetite, nickel laterite and ores containing precious group metals, secondary slag or dust. From a containment perspective, either an insulating cond...

Increasing the efficiency of crushing circuits is associated with a decrease in particle size finely crushed ore and use dry magnetic separation ore. Reducing grinding costs achieved by using drum mills jointly other designs. The automation systems, slurry demagnetization, technologies staged concentrate separation, beneficiation fine screening closed cycle lead to reduction costs. main industr...
