Description

A kind of mineralogical analysis device

Technical field

The present invention is the device that a kind of mineral samplers is analyzed, be applicable to the on-the-spot mineral samplers analysis in mining industry exploration or recovery process, relate to and utilize the high light spectrum image-forming technology that the mineral type in the sample is scanned, utilize the XRF technology that the constituent content in the sample is analyzed.

Background technology

At present, in the mining industry field, can be used in the portable analytical instrument of open-air and field survey or recovery process, mainly be the XRF instrument (XRF) of energy dispersion type, adopt miniature X ray pipe and semiconductor refrigerating detector, can analyze the constituent content of mineral samplers.More famous is the silent Niton XL series of your scientific and technological Ni Tong company of company (Thermofisher Niton) of generation and the Delta series ore assay instrument of company of U.S. Innov-X company (Innov-X) of flying of U.S.'s match.Because unevenness and the complicacy of ore, portable x-ray fluorescence analyzer device can only be analyzed the roughly content of ore, and simple ultimate analysis, can not judge mineral type, has larger limitation.Portable x-ray fluorescence analyzer is mainly used in seeking earth's surface " unusually " at present.In the mining industry field, traditionally, the general X-ray diffraction instrument of costliness that adopts is distinguished mineral type, and in recent years, near infrared and hyperspectral analysis technology also progressively were used for the identification of " alteration " mineral.The high light spectrum image-forming technology is combined with the small-sized XRF technology with the rapid prototyping function, will brings in the mining industry field revolutionary variation.

Summary of the invention

The object of the invention is to propose a kind ofly modularly can be applied to on-the-spot fusion x-ray fluorescent technique and mineralogical composition and the type analysis device of high light spectrum image-forming technology.

Technical solution of the present invention is:

1. mineral samplers is placed on that small-sized platform is fixed or specific groove in (in core box).

2. by small-sized high light spectrum image-forming module, progressively finish from front to back the high light spectrum image-forming scanning to mineral samplers, simultaneously according to the high spectrum image under different wave length, different minerals type to mineral samplers is carried out identification, and identify the locus of record sample with different colours or the depth.

3. quick sample prepares module, utilize the instantaneous fly-cutting of circular Rock cutting cutter, finish drying and powdered to mineral samplers, powdered sample is collected, and automatically be sent to ad-hoc location and compacting, namely can be used as the desirable sample of x-ray fluorescence analysis.

4. the sample of collection and compacting is sent to miniaturization x-ray fluorescence analysis module, carries out the elemental composition analysis.

5. by spatial positional information, high spectrum mineral type identification data and XRF constituent analysis data are carried out combination, provided at last the full geology information of mineral samplers by systematic analysis, realize that the scene of mineral is edited and recorded automatically.

Whole device is by the high light spectrum image-forming module, and sample prepares module fast, the sample supplying system, and x-ray fluorescence analysis module and control and analysis module combinations form.High spectrum module can be finished by the characteristic spectrum zone of searching sample identification and the sign of mineral " alteration " type.In wavelength 1400nm and 2200nm zone, white mica has strong Absorption Characteristics.At the 1950nm place, plagioclase has strong Absorption Characteristics.The XRF module adopts X-ray tube and the electric refrigeration detector of miniaturization, and eliminates or reduce module to the dependence of instance model and matrix with the basic parameter analytical approach.And if do not have effective rapid prototyping equipment, the error that the unevenness of core is brought will make the scene can't any analytical technology of effective application.Quick sample prepares module, can instantaneously finish the quick preparation of sample, obtains the needed desirable sample of XRF module.In the control and analysis module, by the high spectrum mineral kind data the obtained constituent content data in conjunction with XRF analysis, can obtain the content of some mineral species.As the haematite that utilized the discovery of high spectrum in rock sample, and the XRF module has obtained the content 42.18% of Fe element, comprehensive two data can draw, haematite Fe ₂0 ₃Content be approximately 60.26%.The composition of understanding mineral and content all are extremely important to exploitation and the ore dressing of mining industry.The full geologic data information that the characteristic module system that obtains obtains at last also can embed the geography information of sampling region, and combines with the high-spectrum remote sensing of GIS (Geographic Information System) software or this region.

Drawings and Examples:

Fig. 1 is the enforcement structural drawing of this mineral total analysis device, according to analysis sequence, sample 6 is fixed in platform or the groove, and at first 3 pairs of samples of high light spectrum image-forming module of sample carry out image scanning, type identification and spatial information record, subsequently sample preparation module 2 is carried out rapid prototyping to sample.After obtaining certain sample size, through pushing module 5, be sent to x-ray fluorescence analysis module 1 and carry out ultimate analysis, behind 4 pairs of data analysis and integration from high spectrum module 3 and XRF module 1 of analysis module, provide full geology information.Be used for core analysis such as this device, because sample is cylindrical, then example platform can be set to rotation platform, drives the core rotation by belt, thereby finishes the high light spectrum image-forming scanning of whole core.

Fig. 2 is the enforcement structure that quick sample prepares module, the sample preparation module is most important to XRF analysis result's accuracy, because it is evenly dry sample that the energy dispersion XRF take fundamental parameters method as analysis foundation requires sample, and this quick sample prepares quick preparation-powdered that module can be passed through the instantaneous realization sample of disc cutting tool A C, because when sample contacts with the high-speed cutting cutter, the a large amount of thermal energy consumptions that obtain with cutter friction the moisture in the sample, thereby resulting final sample is for having become dry powdered samples, and the sample of these Powdered dryings has obtained certain speed when leaving cutter, casts aside away along the tangential direction of cutter and the last contact point of sample.The sample collection funnel B that arranges in a distance utilizes inertia and the gravity of powder, has realized automatic collection and the homogenising of sample.
