Description
Technical field
The utility model relates to geochemistry and seeks nonferrous metal ore, particularly utilizes earth electrochemical principle to seek the low voltage dipole terrestrial electricity extraction element of latent mineral metal products.
Background technology
Because commercial production is to the heavy demand of nonferrous metal ore resource, the mineral resources of the face of land and superficial part are reconnoitred totally, both at home and abroad the method and technology of seeking latent mineral metal products resource are more and more paid attention to.The conventional geochemical method of seeking mineral metal products at present has protofaint method, secondary halo method, dispersion train method, biomass geochemistry method etc.These methods are composed the form of depositing and the emphasis difference cuts both ways at metallic element is different.For example, the protofaint method takes the basement rock sample to come analytical element content, and this has just required a large amount of basement rock exposures.And the secondary halo method is taked pedotheque analytical element content, but soil is the synthesis result of multiple weathering, and wherein element is through to a certain degree differentiation, and is so close not as protofaint with the relation of ore body; And be subjected to the influence of ground surface environment easily, make the anti-interference and extraneous contamination of this method ability a little less than.This several method is better to seeking the depth of burial little face of land or superficial part ore body effect, and the latent metal ore body of seeking the deep is then loseed effect.
The utility model content
The utility model provides a kind of utilization to add artificial electric field and has extracted metallic element in the soil, by analyzing the low voltage dipole terrestrial electricity extraction element that the metal element content that is extracted carries out deep prospecting.
The utility model is achieved in that by power supply, lead, extraction electrode to be formed.The center of extracting electrode is a graphite carbon rod, is surrounded by sorbing material in the outside of graphite carbon rod, and the outside of sorbing material is surrounded by filter paper; Power supply links to each other with the center graphite carbon rod that extracts electrode by lead.
Dig out a heatable adobe sleeping platform at survey station, dig the soil bottom, put into the hole after electrode (each one of cathode and anode) soaks in extract extracting.The bottom centre that the extraction electrode is placed on the hole fills out the soil that digs out when digging pit, while banket an extract that configures is poured in the soil uniformly, buries the back soil is treaded.To connect the both positive and negative polarity that two leads that extract electrodes are connected with the mains respectively at last.Switch on after 20-48 hour, just can extract electrode and take out, wherein sorbing material dry, numbering and sample presentation chemically examine.
Requiring of each building block of the present invention is as follows: power supply adopts dry cell, and lead is thin copper core metal lead.The step of extracting the electrode making is such: get a graphite carbon rod, end at graphite carbon rod carves a sulculus, by sulculus plain conductor is linked to each other with graphite carbon rod, and seal with the paraffin place that plain conductor is exposed, and the joint of wrapping plain conductor with the waterproof insulation adhesive plaster.Wrap the sorbing material (being generally the height bubble sponge or the absorbent cotton of strong adsorbability) of process respective handling in the outside of graphite carbon rod, wrap filter paper in the outside of sorbing material then, and twine with cotton thread.Should note when making graphite electrode following some: 1) resistance between plain conductor (and power supply join that end) and the graphite carbon rod bottom is about 0.1 Ω, and maximum can not surpass 0.2 Ω, with the assurance excellent conducting performance.2) sorbing material must soak 6-30 hour through the mixed solution with 15%-25% hydrochloric acid and 0.5%-15% thiocarbamide.Its objective is and make original metallic element background uniform contentization in the sorbing material.4) center of extraction electrode is that the square section is circular graphite carbon rod.5) outermost filter paper is that general high speed filter paper gets final product.Its objective is to stop big solid soil particle to enter sorbing material,, influence the prospecting result of this method in case soil particle mixes mutually with the metallic element or the metallic ion of extraction.
In using process of the present invention, should also be noted that following problem:
1) laying of measuring point: the distance between each measuring point can be a distance with 20 meters generally with reference to the geochemical exploration standard for manual sampling of corresponding proportion chi, can encrypt 10 meters some distances during complicated geologic conditions.Interval of survey line is 100M.
2) spacing between the extraction electrode (cathode and anode): be 40-100CM.
3) extract: be a kind of solution in nitric acid, sulfuric acid and the hydrochloric acid of concentration 10%-40%, consumption is 500mL-1500mL.Can suitably strengthen consumption under the special soil condition, as in the serious soil of the salinization of soil of northwest desert.
4) extraction time (conduction time) is preferably 20-48 hour.
The utility model extract to be composed the activity part that has the metallic element among the soil by extra electric field, and this part material is from ore body, and is closely related with ore-forming element or mineralization.These materials are moved to the face of land from the deep under the driving of the electrochemical field specifically that ore body self forms, and under face of land precipitation, enrichment, it is unusual to have formed local geo-electrochemistry.Because its occurrence patterns is comparatively active, be not subjected to obducent shielding of thick-layer and interference, therefore, even under the situation of the big degree of depth, also can have the preferred metal constituent content unusual, this be routine look for the ore deposit can not accomplish.
The utility model is simple to operate, easy to carry, cost is low, high efficiency, easy to operate, seek compared with routinizing and to look for the concealed orebody method that remarkable advantages is arranged, can seek concealed orebody at thick areal coverage, predict in the ore deposit of looking for that is included in external drift load areal coverage such as thick-layer alluvial deposits, deposit, proluvium, predict in the ore deposit of looking at the residual cliff debris areal coverage of thick-layer, and seeks latent mineral metal products at thick-layer basement rock areal coverage.
