Problems solved by technology

However, the buried depth of the ore body is generally 1-10m, so some ore bodies are often ignored, or are lost with the leachate due to surrounding mining, and have not been rationally utilized

Embodiment 1

[0030] Sample from the rock weathering shell of a neutral adsorption-type rare earth deposit in Meizhou, Guangdong Province, in this example, calculated the content of Ce and rare earth elements in different depth samples of the wind and seaside (Table 1), the relative content of the hematite-needle iron ore ( Table 2), the ancient dive level indicated by Δce, hematite-needle iron ore, so that rare earth elements are obviously enriched under ancient dive.

Abstract

The invention discloses a method for predicting the horizon of a weathering crust ion adsorption type rare earth ore deposit based on the ancient phreatic level. The samples of the weathering crust are collected for trace element analysis and visible light-near-infrared reflection spectrum analysis, and the Ce content in the whole rock of the weathering crust is calculated. The change is the δCe and the absorption peak position of the visible light-near infrared reflectance spectrum in the 480-530 nm band (P500), which can characterize the relative content of hematite-goethite. The boundary line is the paleophrenic level of the weathering crust, and the rare earth element rich ore horizons in the weathering crust are distributed below the paleophrenic level. To further improve the accuracy of delineating the ore body and evaluating the reserves of the weathered ion adsorption rare earth deposit, and to meet the purpose of the efficient utilization of rare earth resources by the prospecting and exploration of the weathering crust ion adsorption rare earth deposit.

Description

Technical field [0001] The present invention belongs to the field of rare earth mine exploration, and in particular, the present invention relates to a method of predicting a radiochemical housing ion adsorption type rare earth deposit by ancient submersible position. Background technique [0002] The rare earth elements are widely used in many applications such as defense military, aerospace, special materials, metallurgy, energy and agriculture, known as "industrial vitamins". In recent years, the rapid development of aerospace, new energy and new materials has made rare strategic resources. Since Western developed countries have increased year by year, rare earth (especially heavy rare earth) in the international market continues to rise. Driven by market demand and economic benefits, all countries in the world attach great importance to exploration and development and utilization of rare earth deposits in recent years. The weathering ion adsorption-type rare earth deposit in ...
