Problems solved by technology

[0006] At present, when measuring rutile-type titanium dioxide in titanium ore minerals in rock and mineral analysis laboratories, since there is no national and industry standard method, different provincial (city) geological and mineral laboratories have different analysis methods for testing rutile-type titanium dioxide, and Lead to poor accuracy and repeatability of test results, and low satisfaction with test results
At present, when measuring rutile titanium dioxide in titanium ore, the traditional method adopts zinc flake reduction-ferric ammonium sulfate titration method, hydrogen peroxide spectrophotometry, diantipyrine methane photometry to measure, and the steps in the determination process are cumbersome. The operation cycle is long, the amount of chemicals is large, the environmental pollution is serious, the accuracy of the method is not high, the repeatability of the experiment is poor, and the confidence of the method is low

Embodiment 1

[0076] The present embodiment provides a kind of method for measuring rutile TiO in titanium ore, specifically:

[0077] 1) Weigh 0.2000g (accurate to 0.0001g) titanium ore ore sample, add 50ml (2+1) HCl (hydrochloric acid to water ratio 2:1) and 2.0g NaF mixed solvent, cover with a watch glass, in boiling water Dissolve ore in the bath for 1.5 hours, stirring continuously during the period; then cool, filter with slow dense quantitative filter paper, and wash the residue with hot water for 5-6 times;

[0078] 2) Remove the residue together with the filter paper and place it in a high-alumina crucible, start ashing in a muffle furnace from a low temperature (below 300°C) (open the furnace door for ashing, close the furnace door after the smoke is exhausted), and reach 700 °C ℃, a total of 20 minutes, take it out, cool, add 1g of sodium hydroxide, shake well, cover the surface with a little sodium peroxide (about 0.2g), and melt ore in a muffle furnace at 700℃ for 10 minutes; ...

Abstract

The invention relates to a method for testing and determining rutile TiO2 in titanium ore. The method specifically comprises the following steps that ore dissolving treatment is performed on a titanium ore sample by adopting a hydrochloric acid-sodium fluoride system to obtain residues; then alkali fusion treatment is performed on the residues by adopting a sodium hydroxide-sodium peroxide system;then the residues are extracted through hot water and are dissolved in an acid to obtain a to-be-tested solution; a TiO2 standard solution with gradient concentration is prepared; and then an inductively coupled plasma-atomic emission spectrometry is adopted for testing and determining, a spectral intensity value is obtained, moreover, a standard curve is drawn, and the content of rutile TiO2 iscalculated. According to the method, the content of rutile TiO2 in the titanium ore can be rapidly and accurately tested and determined, the problems that in a traditional method, the use amount of chemicals is large, the consumed time is long and the working efficiency is low are solved, moreover, the reproducibility and the accuracy of the rutile TiO2 testing and determining result are improved,more accurate experimental data are provided for geological exploration work, and the method is suitable for analysis work of large-scale geological exploration samples.

Description

technical field [0001] The present invention relates to TiO 2 The detection method, specifically relates to a method for determining rutile TiO in titanium ore 2 Methods. Background technique [0002] Rutile is one of the most important titanium minerals among more than 70 known titanium-bearing minerals. Rutile is an important mineral raw material for extracting titanium. Because of its excellent properties such as high temperature resistance, low temperature resistance, corrosion resistance, high strength and small specific gravity, it is widely used in military industry, aviation, aerospace, navigation, machinery, chemical industry, seawater desalination and other fields. . In recent years, with the development of my country's titanium industry, the demand for raw material rutile has increased sharply, so it is imperative to accelerate the development of this mineral resource. [0003] In nature, there are rutile, anatase and brookite, which are three variants of tita...
