1.X x ray diffraction analysis x
The X-ray diffraction result MSDS of model Imported Manganese Ore and manganese metallurgical slag.The present invention is to 15 national manganese ores, the manganese metallurgical slag of 3 kinds of different process carries out X diffraction analysis, obtain respectively diffractogram, (see Fig. 1 as an example of Australian manganese ore and the cooling slag of air example, Fig. 2), the X-ray diffraction result MSDS that diffracting spectrum has been set up Imported Manganese Ore and manganese metallurgical slag is by analysis in table 3, table 4.
Manganese metallurgical slag diffraction spectrogram analysis to every country manganese ore, 3 kinds of different process is visible, Imported Manganese Ore is mainly taking pyrolusite, manganese oxide, manganosite, braunite, rhodochrosite and quartz as main, and all manganese ores all have crystalline form, so all have its feature XRD spectra, country variant manganese mineral facies type is as shown in table 3.Manganese metallurgical slag is that the phase character of ferrosilite, clinopyroxene and tephroite is main, or owing to not having crystal habit to cause not having characteristic XRD figure, in table 4, this point is also a distinctive points of manganese metallurgical slag and manganese ore simultaneously, because all manganese ores are all products of spontaneous nucleation, all belong to crystalline solid, and Water Quenching Slag do not have specific crystal formation.Hence one can see that, and manganese metallurgical slag is compared with manganese ore, and its thing phase key distinction is to contain ferrosilite and tephroite, or there is no XRD feature spectrogram.For the Water Quenching Slag that there is no crystalline form, can further be assisted discriminating by diffuse reflectance infrared spectroscopy.
A, manganese ore X diffraction conclusion:
The common feature of Imported Manganese Ore is taking manganese oxide, pyrolusite, manganosite, rhodochrosite, braunite as main, or individualism, or several mixing.Other oxide mainly taking things such as quartz mutually as main.
B, manganese metallurgical slag X diffraction conclusion:
The feature of manganese metallurgical slag is mainly the feature of ferrosilite and tephroite, or does not have characteristic XRD figure.
Produce known following 3 points of principle by manganese metallurgical slag: the first, while producing several alloy of manganese with blast furnace, need in raw material, add silica, after high-temperature fusion, generate the mineral that contain silicate, as ferrosilite.So in the slag that the manganese ore after smelting produces, from the angle analysis of chemical composition, contain a large amount of SiO 2, from the angle analysis of thing phase, all have the mineral containing silicate class.The second, producing in the technique of silicomangan, add raw material rauhkalk and lime, so CaO content is also very high in the manganese metallurgical slag of generation.The 3rd, while producing manganeisen, give off manganese slag, granular for shrend, be at high temperature molten condition, and obtain through shrend chilling, do not form good crystallization, admittedly there is no specific crystalline form, cause not having characteristic XRD spectra.
Therefore just can draw above-mentioned conclusion by X-ray diffraction analysis.
2. ftir analysis
The present invention is to 15 national manganese ores, and the manganese metallurgical slag of 3 kinds of different process carries out Infrared spectroscopy, has obtained respectively infrared spectrogram, taking Australian manganese ore and the cooling slag of air as example (seeing Fig. 3, Fig. 4), and has summed up its infrared signature separately.
The analysis that import is carried out to infrared signature peak from these 15 national manganese ores draws: manganese ore mainly contains the infrared signature of two types: the one, and, at 691cm -1, 538 cm -1, 411 cm -1there is very strong absorption peak at wave number place, is the characteristic peak of manganese oxide; Or at 685cm -1, 550 cm -1, 410 cm -1there is very strong absorption peak at wave number place, is the characteristic peak of pyrolusite, all belongs to the absorption of vibrations of Mn-O, belongs to oxide mineral, at 1000 cm -1more than do not have characteristic infrared absorption.The 2nd,, at 1420 cm -1there are wide strong absorption peak, 881 cm in place -1, 729 cm -1all there is sharp-pointed absorption at place, is the characteristic peak that contains rhodochrosite, and its ownership is respectively: at 1420 cm -1near wide strong absorption belongs to C-O stretching vibration, 881 cm -1what locate is C-O in-plane bending vibration, 729 cm -1the absorption at place is C-O out-of-plane bending vibration.Because rhodochrosite belongs to carbonate mineral, so there will be the infrared signature absorption peak of obvious C-O vibration, meanwhile, because containing different cationic impacts, characteristic peak has certain displacement.
If this manganese ore belongs to rhodochrosite type, its infrared spectrum is respectively at 1420 cm -1, 881 cm -1, 729 cm -1there is characteristic absorption peak (Fig. 5) clearly at three places, otherwise its characteristic absorption peak is only at 1000 cm -1below there is strong absorption peak (Fig. 3).These conclusions are consistent with the conclusion of X-ray diffraction.
Manganese metallurgical slag infrared spectrum analysis to 3 kinds of different process is visible, and the manganese metallurgical slag of this three types has identical infrared signature peak, at 960cm -1near have wide strong absorption peak, and be the strongest absorption band in whole spectrogram.It is attributed to Si-O stretching vibration absorption band.For the Water Quenching Slag that there is no XRD characteristic peak, infrared spectrum also can draw definite conclusion (Fig. 6), has made up the defect of XRD.
A, manganese ore infrared absorption conclusion:
The common feature of Imported Manganese Ore is, only at 600 ~ 400 cm -1in scope, have two strong absorption bands, bands of a spectrum are wider.Except rhodochrosite is at 1420 cm -1place has outside characteristic absorption peak, and other type manganese ore is at 1000cm -1more than there is no strong absorption peak.
B, manganese metallurgical slag infrared absorption conclusion:
The feature of manganese metallurgical slag mainly, at 960cm -1have the strongest wider absorption peak, meanwhile, the manganese ore that process is smelted is at 1420 cm -1place does not necessarily have characteristic peak.
 
By manganese ore and the analyses and comparison of manganese metallurgical slag are studied, both can differentiate by X-ray diffraction and Infrared spectroscopy.Concrete grammar is:
A, sample preparation to be identified: be ground to by 200 mesh sieves, 105 DEG C of oven dry, put into exsiccator and be cooled to room temperature.
B, X-ray diffraction spectroscopic methodology: search the feature that whether has obvious ferrosilite and tephroite in spectrogram, or do not have characteristic XRD figure.Whether can tentatively confirm sample is manganese metallurgical slag.
C, infra-red sepectrometry: whether search in infrared spectrum at 960cm -1there is the strongest wider absorption peak, and at 1420 cm -1place does not have characteristic peak, can assist whether confirmation sample is manganese metallurgical slag.
For unknown manganese ore sample identification testing process
The progressively division of the sample of a, extraction, be crushed to all by 200 eye mesh screens
B, by sample in 105 DEG C of oven dry, be placed in exsiccator and be cooled to room temperature
Sample is carried out to X-ray diffraction analysis, as having the feature of obvious ferrosilite and tephroite in sample after testing, or do not have characteristic XRD spectrum peak, can tentatively confirm sample is manganese metallurgical slag, as without this obvious characteristic, needs infrared spectrum to detect.
C, sample is carried out to infrared spectrum detection: whether search in infrared spectrum at 960cm -1there is the strongest wider absorption peak, and at 1420 cm -1place does not have characteristic peak, and can confirm sample is manganese metallurgical slag.
Embodiment 1: the qualification of manganese metallurgical slag
First to sample drying and processing, then preparation, by 200 eye mesh screens.
Adopt X-ray diffraction spectral analysis: the sample of selecting is carried out to the spectrum peak of obvious tephroite in X-ray diffraction spectral analysis discovery sample, therefore judge that this sample is manganese metallurgical slag, and be rich manganese slag.
Adopt Infrared spectroscopy: this sample is carried out to Infrared spectroscopy, can find out the characteristic peak that has obvious manganese metallurgical slag, as Fig. 7.Can judge that this sample is manganese metallurgical slag.
According to the above description, can realize the solution of the present invention in conjunction with art technology.
