Embodiment 1

[0027] 1. Composition design, design according to the composition in Table 1.

[0028] 2. Standard product preparation

[0029] When selecting candidates, we went to multiple manufacturers to sample more than a dozen varieties of products, compared them with the design components in Table 1, and finally determined three bauxite blocks (powder powders) that meet the design requirements. ) as candidates for standard sample preparation. Bauxite (Al 2 o 3 -46) is massive (particle size 2 o 3 -83), bauxite (Al 2 o 3 -88) in powder form, 300kg each was taken as a candidate for standard sample preparation. Bauxite (Al 2 o 3 -60), bauxite (Al 2 o 3-70) Because no very suitable candidates were obtained, the ingredients in Table 1 were formulated.

[0030] Crush the blocky sample with a jaw crusher to less than 3 mm, and then place the sample in a ball mill for ball milling; after the ball milling, sieve through a 180-mesh (0.083 mm) standard sieve, and discard the sieve. Th...

Abstract

The invention discloses a set of alum clay standard samples, belonging to the technical fields of new materials and metallurgical analysis. The set comprises five samples of which the Al2O3 contents are respectively 45-50wt%, 60-65wt%, 70-75wt%, 80-85wt% and 85-90wt%; and the five samples are simultaneously used for determining the contents of 12 components such as Al2O3, CaO, MgO, P2O5, Fe2O3, TiO2, SiO2, K2O, Na2O and the like. The set of alum clay standard samples covers the typical composition points of the currently used alum clay such as laterite, alumina, bauxite and the like. The standard samples are used for testing the quality of alum clay products, performing evaluation and unified measurement test on a calibration and measuring method of a measuring instrument, performing production control analysis on the products, and evaluating the technical levels of laboratories and analysis staff; and meanwhile, the standard samples are also applicable to the evaluation and arbitration of such products in external technical exchange and trading.

Description

technical field [0001] The invention relates to a set of bauxite standard samples and a preparation method thereof, belonging to the technical field of new materials and metallurgical analysis. Background technique [0002] The main component of bauxite is Al 2 o 3 , is an important raw material for refining aluminum, and is an important raw material for the electrolytic aluminum industry to manufacture alumina and aluminum hydroxide. Bauxite is widely used in aluminum smelting industry, precision casting, refractory products, aluminum silicate refractory fiber, open hearth furnace, converter steelmaking flux, etc. According to the iron content, bauxite can be divided into iron bauxite for metallurgical industry and bauxite for non-ferrous industry. The main chemical composition of bauxite is Al 2 o 3 , SiO 2 , Fe 2 o 3 ,TiO 2 , accounting for about 95% of the total composition, the minor components are CaO, MgO, K 2 O, Na 2 O, MnO 2 And organic matter and trace ...
