Method for predicting concealed ore deposit by utilizing chemical component data of single nanoparticle

Abstract

The invention belongs to the technical field of geological survey and particularly relates to a method for predicting a concealed ore deposit by utilizing chemical component data of a single nanoparticle. The method comprises the following steps: collecting a detected sample, preparing the detected sample into a test sample, analyzing single nanoparticles in the test sample by adopting a probe technology, carrying out qualitative and quantitative analysis on elements in the single nanoparticles, and predicting a concealed deposit according to chemical component data obtained by analysis. By qualitatively and quantitatively analyzing the elements in the test sample and predicting the concealed ore deposit according to the obtained chemical component data, the qualitative leap of prospectingdata from semi-quantification to quantification can be realized, more accurate and richer information about concealed ore bodies is obtained, and the prospecting cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of geological survey, in particular to a method for predicting hidden ore deposits by using the chemical composition data of a single nanoparticle. Background technique [0002] With the rapid development of social economy, the existing surface resources can no longer meet the development needs of the national economy. In order to meet the rapid development of the economy's demand for mineral resources, it is urgent to carry out the exploration of deep hidden ore bodies. The characteristics of large burial depth and few outcrops have brought many difficulties to the prospecting work, especially in some areas with thick overburden. [0003] Geophysics and geochemistry are commonly used methods for prospecting. Geophysical prospecting methods cannot directly obtain information on mineralization anomalies. The element anomalies based on geochemical prospecting methods can have various background reasons. The da...
