Foamed-plastic carried extraction and exploration method of blind uranium ore deposit

Abstract

The present invention relates to the ore prospecting of blind uranium ore deposit and is one foamed plastic carried extraction and exploration method. Foamed high density polyurethane plastic carrying PMBP or N263 with very high adsorption to uranium (VI) is used as extracting material in adsorption extracting exploration or constant-voltage adsorption extracting exploration. The said method can find uranium ore deposit buried deep under to 400 m depth, and the present invention solves the difficult problem of finding blind uranium ore deposit. The present invnetion includes the preparation of foamed plastic carrying PMBP or N263 and field extraction job. The present invention has the features of great information amount, high abnormal peak, great enrichment coefficient and good ore finding effect.

Description

technical field [0001] The invention relates to a method for prospecting and exploring hidden uranium deposits; in particular, it relates to a method for extracting and exploring loaded foam plastic. Background technique [0002] The method of prospecting and exploration of concealed uranium deposits has always been a key technical issue that puzzles the development of my country's nuclear industry. In the past, traditional geophysical and geochemical prospecting methods were used in my country, such as soil secondary halo measurement method, activated carbon adsorption method, potential measurement method in geochemical prospecting, excitation method, transient electromagnetic method, and even geophysical prospecting method. Low-frequency measurement method and gamma spectrometry of radioactivity measurement, etc. The above-mentioned geochemical prospecting methods have little ore prospecting effect for the general prospecting of deep hidden uranium deposits because the amo...

Problems solved by technology

However, it has to be pointed out that the methods mentioned above are all indirect prospecting methods except the diffusion extraction method and the salt ion complex prospecting method, which consume a lot of manpower, material resources and financial resources, and the cost is high.

Although the salt ion complex prospecting method, diffusion extraction method and gas ion state method invented in Russia can discover hidden uranium deposits below 400 meters deep, they have not been widely used in my country due to limited use conditions and high costs.
