EARLY METHOD OF PROCESSING ILMENITE In the early method of TiO2 pigment manufacture from ilmenite the ore was treated with concentrated H2SO4 at 110–120°C to form ferrous and titanyl sulfates: FeTiO3 + 4H+ → Fe2+ + TiO2+ + 2H2O (1) The solidified mass produced in the reactor at the end of the reaction was then discharged from the reactor ...

for ilmenite concentrate fraction, mineralogical, and thermographic analyses. Results of studying physicochemical properties of Shokash ilmenite concentrate and its charges with reducing agents may be used in creating production schemes for further processing. The most rational method is determined for charge agglomeration, i.e., briquetting.

Processing titanium ore includes several stages for extracting titanium and turning it into a final product. Our company has developed 2 main concepts for dressing titanium ores, the main feature of which is the method of obtaining ilmenite concentrate: 1. Scheme of magnetic, flotation, and electrostatic separation: 2.

Ilmenite concentrate processing method involves its exposure by means of a sulphatising reagent with subsequent separation of titanium compounds from iron compounds. Opening is carried out in solid phase by roasting concentrate with excess of ammonium sulphate as sulphatising reagent at 360–400 °C for 4.0–4.5 h. Formed product is leached ...
