beneficiation of massive ilmenite by froth flotation - sciencedirect

An attempt has been made in this investigation to enrich massive ilmenite ore of Sambalpur by froth flotation. Two approaches were made to this end. In the first, which was carried out in an alkaline medium, the gangue minerals were removed from the float and the ilmenite concentrate was collected as sediment. The ore could be enriched to a maximum TiO2 content of only 37% at a pH of 10.75, pulp density of about 150175 g/litre and at a collector concentration of 1.25 kg/tonne of ore. In the second approach the ilmenite was made to float in an acidic medium with a combination of anionic and cationic collectors (oleic acid and lauryl trimethyl ammonium bromide respectively) and with soda ash and sodium hexametaphosphate usages of 0.1 and 0.2 kg/tonne of ore respectively, as the depressants for iron minerals. A factorial design technique was applied to find out the optimum level of pH, oleic acid and lauryl trimethyl ammonium bromide to give maximum enrichment and recovery. A concentrate of maximum 51.62% TiO2 with 84.63% recovery could be obtained at a pH of 3.4, oleic acid of 0.6536 kg/tonne and lauryl trimethyl ammonium bromide of 0.150 kg/tonne of the ore.

The future utilization trend of titanium resource will be largely relied on ilmenite.Combined processing technologies will be more effective in ilmenite dressing.Flotation proves to be an indispensable step for ilmenite upgrading in future.Future research needs on ilmenite beneficiation are discussed.

Ilmenite, as the main titanium source in practice, is of critical importance in meeting the pressing needs of various titanium associated fields. Herein, a review of ilmenite mineral processing by flotation is conducted to systemise the development of technologies in ilmenite upgrading. It proves that Australia and China are the top two countries with higher titanium reserves than other countries but with different metallogenic mechanisms. The basic properties of ilmenite and its metallogenic mechanism codetermine the final choice for ilmenite-containing ores beneficiation. Flotation has been an indispensable step for ilmenite upgrading as time goes and many collector types that can float ilmenite in different pH ranges have been developed. To date, various surface modification methods have proven to be a research hotspot. How to improve the flotability of fine ilmenite and comprehensive recycling of those historic ilmenite-containing tailings are much deserved in future.

NaOL-DAA shows a high selectivity for flotation of ilmenite from titanaugite.The optimum molar ratio of NaOL and DAA in mixed collectors is found to be 10:1.The NaOL-DAA co-adsorption on titanaugite surface is much weaker than on ilmenite.The NaOL-DAA complex adsorbs on ilmenite surface by chemical adsorption.

The flotation behavior of ilmenite and titanaugite using anionic collector sodium oleate (NaOL), cationic collector dodecylamine acetate (DAA) and the mixed anionic/cationic collector (NaOL-DAA) was investigated through micro-flotation experiments, zeta potential measurements, Fourier transform infrared (FTIR) analyses, and the artificially mixed minerals flotation experiments. The results of the microflotation experiments indicate that DAA exhibits good flotation performance to both ilmenite and titanaugite at a pH>6.0. The flotation separation of ilmenite from titanaugite can be performed using the mixed NaOL-DAA in a wide pH range of 5.07.0. In this pH range, the recovery of ilmenite remains constant at approximately 90%, while the recovery of titanaugite remains <25%. The best separation result can be achieved with NaOL-DAA molar ratios of 10:1. The results of the zeta potential experiments and the FTIR analyses indicate that the adsorption of the mixed collector, NaOL-DAA, on the ilmenite surface is larger than on the titanaugite surface and that the NaOL-DAA complex might be mainly adsorbed on the ilmenite surface by chemical adsorption, apart from electrostatic adsorption. The synthetic mineral mixture micro-flotation results demonstrate that, compared to NaOL, NaOL-DAA not only increases the recovery and grade of the TiO2 by 7.02% and 6.71%, respectively, but also decreases the reagent consumption by half.

surface modification of ilmenite and flotation improvement using fenton as an oxidant - sciencedirect

surface modification of ilmenite and flotation improvement using fenton as an oxidant - sciencedirect

Ilmenite can be greatly activated using Fenton as the oxidant and surface modifier.Fenton pretreatment promoted the conversion of Fe2+ to Fe3+, increasing the active sites on ilmenite surfaces.Fenton pretreatment enhanced the interaction between Fe sites on ilmenite surfaces and sodium oleate.

In this work, we propose a new method to activate ilmenite using Fenton as an oxidant and a surface modifier. The activation mechanism of Fenton on ilmenite was investigated through micro-flotation experiments, zeta-potential measurement, adsorption tests, Fourier transform infrared (FT-IR) spectroscopy, and X-ray photoelectron spectroscopy (XPS). Both the micro-flotation and adsorption experiments showed that flotation recovery of ilmenite was significantly improved after activation by Fenton. Compared with ilmenite without Fenton activation, zeta-potential measurement and XPS analysis demonstrated that the number of active sites on the surface of ilmenite increased. A new characteristic adsorption peak appeared in the FT-IR spectrum, and chemical adsorption of oleic ions on the surface of ilmenite was improved after treatment with Fenton. Therefore, Fenton activation promotes the conversion of Fe2+ to Fe3+ on the mineral surface and enhances adsorption of the collector to ilmenite, thereby increasing ilmenite recovery.
