Problems solved by technology

With the increase of the depth of ore prospecting, the original conventional gross geochemical prospecting method is difficult to find the abnormal total amount of uranium and its associated elements on the surface above it, so the conventional gross geochemical prospecting method detects the presence of large uranium deposits in deep areas. limitations

Embodiment

[0035] (1) Use tools such as shovels and hoes to dig a pit with a depth of 70 cm and a diameter of about 30 cm at the measurement position determined by a certain mesh.

[0036] (2) at the deep 50cm place in the center of the pit of above-mentioned steps (1), suspend a semipermeable membrane cylindrical bag that nitric acid solution is housed, and the cylindrical bag is long 25cm, and diameter is the long tubular casing film of 1.5cm, and volume is housed inside The percentage concentration is 30mL of nitric acid solution of 3%, and the two ends of the enteric membrane are tied tightly with plastic silk. This enteric membrane is a semi-permeable membrane, which can only allow the earth's air flow to carry the active nano-uranium and other nano-metal particles and ions in the soil gas from the deep uranium ore body, and the nitric acid from the soil gas to diffuse into the membrane. In the solution, the particles and ions inside cannot seep out of the membrane.

Abstract

The invention belongs to the technical field of uranium ore exploration, and specifically relates to a method for extracting deep uranium mineralization information in soil gas; A method for extracting deep uranium mineralization information in soil gas extracted from active nano-uranium in soil gas of deep uranium mineralization information; the invention is an innovative extraction method of deep uranium mineralization information, which can effectively solve the problem of conventional The exploration method cannot detect the key technical problems of hidden deep uranium deposits. The actual ore prospecting test shows that the developed method of extracting nano-uranium with deep uranium mineralization information in soil gas by using casing semi-permeable membrane makes the abnormality of active nano-uranium more obvious and clear. , The anomalous contrast is large, which greatly improves the effectiveness and practicability of the soil active nano-uranium geochemical method for prospecting deep uranium deposits.

Description

technical field [0001] The invention belongs to the technical field of uranium ore exploration, and in particular relates to a method for extracting deep uranium mineralization information in soil gas. Background technique [0002] At present, my country's nuclear industry has entered a stage of rapid development, especially with the development of nuclear power, the demand for uranium resources has grown rapidly, and uranium resources have become an important pillar for the sustainable development of my country's nuclear power. After more than 60 years of uranium exploration in my country, most of the superficial ore and outcrop mines have been discovered. In recent years, the main task of geological prospecting has shifted to finding deep concealed medium and large uranium deposits. With the increase of the depth of ore prospecting, the original conventional gross geochemical prospecting method is difficult to find the abnormal total amount of uranium and its associated el...
