Technical Field

The invention relates to an ion adsorption and collection device, in particular to an ion adsorption and collection device used in an electro-adsorption ore-finding method.

Background

Along with the continuous deepening of the ore finding degree, the easily found outcrop ore and shallow buried ore are less and less, the ore finding target gradually shifts to the difficultly found deep buried ore, and the ore finding difficulty is higher and higher.

In recent years, research at home and abroad shows that the diagenesis, magma action, metamorphism, structural deformation, mineralization transformation and hydrothermal boiling action still exist around the ore body, and under the erosion of the geological action of the ore body, the derived liquid contains a large number of elements which have direct relation with the ore body, and the elements can laterally and vertically move in a relatively closed geological environment along the tracks of stress difference, temperature difference, salinity difference and density difference. The mineralizing elements and associated elements which migrate to the shallow layer are easily blocked by geochemical barriers such as organic matters, iron-manganese oxides, hydroxide colloids and the like to form the metagenetic geochemistry anomaly. If the anomaly is a strong anomaly, the anomaly is easily discovered by the past geochemical prospecting method, and if the anomaly is a weak anomaly, the anomaly is difficult to discover. Many experts in mineral exploration seek minerals by enhancing anomalies (e.g., partial extraction, complex method, field geoelectric extraction, etc.).

The electro-adsorption prospecting method refers to a prospecting method for discovering the metageochemical abnormality by a physical and chemical means, and is also a prospecting method for strengthening the abnormality. The electro-adsorption method for finding ore is proposed by the inventor group (Zhouqiming. effect of quickly finding blind deposit by electrical geochemistry [ J ]. mineral and geology. 2001.15(4)), and is characterized by that the sample is placed in a special device indoors, a specially-prepared cosolvent is added, then the electric treatment is carried out, and the post-generated geochemical abnormal component in active state is released, and further enriched and strengthened so as to attain the goal of finding ore by using it. The electro-adsorption method is used for searching metal mineral products as a direct index, extracted elements are main mineral forming elements and associated elements, deep mineral species can be directly reflected according to the combination of abnormal elements, gold is abnormally prominent if gold ore, lead and zinc are abnormally prominent if lead and zinc ore, copper is abnormally prominent if copper ore and the like. Through retrieval, no relevant report about finding a device for an electro-adsorption ore-finding method is found at present.

The path of the connecting channel of the sample cell and the first collection vessel and the connecting channel of the sample cell and the second collection vessel may be cylindrical, square in shape. In order to realize that the connection channel and the through hole on the diaphragm plate form the only path for fluid communication among the sample tank, the first collecting tank and the second collecting tank when the diaphragm plate is inserted into the clamping groove, the through hole on the diaphragm plate should be arranged at a position where the through hole on the diaphragm plate at least has a part intersecting with the connection channel when the diaphragm plate is inserted into the clamping groove, and preferably, the through hole on the diaphragm plate is just positioned in a range covered by the longitudinal section of the connection channel or completely coincides with the connection channel.

The device of the invention is practically applied in a uniform electric field environment. In the uniform electric field, the field intensity is equal and the direction is the same, the electric field lines of the uniform electric field are a group of parallel lines with the same density, in the uniform electric field, the force of the electric charges in the electric field is constant, and the charged particles move in the uniform electric field with uniform speed change and are directionally migrated. The equipotential surfaces of the electric field are now perpendicular to the electric field lines. Aiming at different samples, in order to better separate ions, the voltage of the electrode can be changed, pulse current with different frequencies can be selected, so that the electric field has certain elastic action, the separation of complex anions in the test sample is accelerated, the complex anions move to be enriched to the anode, and the complex anions are collected through the adsorption medium of the collecting tank for further analysis.

In practical application, after a sample collected in an ore exploration area is subjected to conventional treatment (for a soil sample, natural granularity is adopted, soil with 80-120 meshes is collected after sieving and used as a test sample, and for a rock sample, the soil is crushed to 200 meshes and used as a test sample), the sample is placed in the sample tank 8 in the ion adsorption and collection device with the diaphragm plate 7 inserted, meanwhile, the auxiliary agent is added to activate different elements in the sample, so that ions with different adsorption positions in the sample are sequentially separated in an electric field environment, and after the ions are enriched through the adsorption media in the first collecting tank 9 and the second collecting tank 6, different element component results can be obtained through test analysis on the adsorption media. Meanwhile, ions of the mineralized elements and associated elements adsorbed in the sample are exchanged, diffused and migrated under different intensities and different frequencies of electric fields due to different formation reasons (for example, different mineralized backgrounds exist, the time for reaching the ground surface is different, the ion concentrations in different time periods are different, and the positions adsorbed on the sample or the combination and wrapping forms are different), and the ions migrate to the positive electrode and the negative electrode respectively under the action of the electric fields with different frequencies. The data provides basis for the analysis of the migration and enrichment rules of the mineral deposit elements formed in different periods, and has very important basis function in guiding the prediction of finding the ores. The testing time is preset according to needs, generally ranges from 1 h to 48h, and the specific time can be determined through tests in advance.

In a particular embodiment, the electrolytic cell 1 and the cover plate 2 are hinged. The sample cell 8, the first collecting tank 9 and the second collecting tank 6 on the electrolytic cell 1 are all square cells, and the central lines of the sample cell 8, the first collecting tank 9 and the second collecting tank 6 in the horizontal direction are coincident; the end of the first collection groove 9 away from the sample groove 8 extends into the body in the direction away from the sample groove 8, so that the second collection groove 6 has a part covered by the body, and the end of the second collection groove 6 away from the sample groove 8 extends into the body in the direction away from the sample groove 8, so that the second collection groove 6 has a part covered by the body; the connection channels between the sample well 8 and the first collection well 9 and between the sample well 8 and the second collection well 6 are all cylindrical (i.e. circular in longitudinal cross-section), and when the diaphragm plate 7 is inserted into the clamping groove 12, the through hole 14 in the diaphragm plate 7 completely coincides with the connection channels. The isolating membrane is a PE isolating membrane, and the isolating membrane is arranged on the diaphragm plate 7 in a mode that the isolating membrane covers the whole diaphragm plate 7.
