The common process involved in ilmenite alteration is the hydration and conversion of ilmenite into pseudorutile, with a Ti/(Ti + Fe) ratio between 0.5 and 0.6 due to iron leaching. The observed Ti/(Ti + Fe) ratio for the ilmenites of São José do Norte shows that most of the data are within the range of 0.50–0.65.
As fine-grained mineral particles will deteriorate the flotation process; −20 μm size fraction (accounting for nearly 30% TiO 2 of the raw ore) of the feed for recovering ilmenite is screened out prior to magnetic separation and directly discharged into tailings, resulting in the low titanium utilization rate and a great waste of ilmenite ...
Panzhihua ilmenite, located in Sichuan province of southwest China, is the largest ilmenite reserve in the world, with an estimated reserve of 870 million tons.This deposit accounts for more than 90% of the total titanium resource of China and over 35% of the world. In the present processing flowsheet, the ore is first processed with wet low-intensity drum …
The degree of ilmenite transformation is lower in a resistance furnace at 1100°C than in microwaves at 850°C, the processing time being the same. The effectiveness of microwave processing for the ilmenite ore and, accordingly, the intensity of phase transformations in the material are significantly influenced by the powder …
Below Region C, the Fe/Ti atomic ratio shifts briefly to near unity before changing, in. 1532.pdf. Region B, to a second set of slightly Fe-depleted values (Fe/Ti ~ 0.8-0.9). Region B is about 50 nm thick and transitions to the bottom or "base" layer of un-altered ilmenite at a depth of ~100 nm.
