1989年6月1日 · An ilmenite concentrate of 47.4% Ti02 has been obtained by froth flotation of an ilmenite ore containing 9% Ti02 using acidified sodium silicate as a gangue depressant and benzyl arsonic acid as the collector.

2022年1月15日 · Arsenic acid possesses the most negative adsorption energy of –148.4 kcal/mol, suggesting it has the best chelation ability with ilmenite. The chelation abilities of phosphorous acid and phosphoric acid ester are next to arsenic acid, the corresponding adsorption energies are –135.8 and –134.3 kcal/mol, respectively.

2022年1月15日 · Adsorption energy results shows that the O bearing pnictogen compounds are the best for ilmenite beneficiation among all the oxygen-containing collectors. In the O-bearing pnictogen compounds, the collection performance of arsenic acid is the best, followed by phosphorous acid and phosphoric acid ester.

2020年10月1日 · Combining the lead ion (Pb2+) and the benzyl hydroxamic acid (BHA) into a Pb—BHA complex has a marked effect on ilmenite flotation, which puts forward a new idea of developing combined reagents...

2023年3月26日 · Herein, this review aims to firstly analyze the crystal structure and solution chemistry of ilmenite and then provide a concise summary of recent advances in different oxidation technologies for promoting the conversion of Fe 2+ to Fe 3+, including hydroxyl radicals oxidation, direct chemical oxidation, and thermal oxidation, and the in-depth ac...

2007年1月1日 · A method for the determination of arsenic in ilmenite by graphite furnace atomic absorption spectrometry (GFAAS) with microwave digestion and ion exchange resin separation was established.

It is the present invention relates to a kind of ilmenite dust treatment method, in particular to a kind of that arsenic in ilmenite flue dust is leached, is turned Type and the method for...

In this study, the oxidation roasting was used to modify the ilmenite chemistry to improve the collector adsorption and ilmenite flotation behavior. The results indicated that the increase of the…

2019年3月20日 · In this work, Fe2O3/TiO2 composite was sustainably prepared via the treatment of titanium slag with a low-concentration sulfuric acid solution (20%) and used for the removal of As(V) from aqueous...

Fe2O3/TiO2 composite has been extensively studied for heavy metals removal and photocatalysis. In photocatalysis, this composite was used for the degradation of organic dye pollutants. Herein, we reported a green approach to fabricate Fe2O3/TiO2 nanoparticles from …
