Method for quickly judging whether black rock series has uranium-free multi-metal mining value or not

Abstract

The invention belongs to the technical field of uranium mines, and particularly discloses a method for quickly judging whether a black rock series has uranium-free multi-metal mining value or not. Themethod comprises the steps of: step 1, acquiring a black rock series sample acquisition; step 2, measuring P2O5 content, V, Ni, Cu and Zn element content and the U-Pb isotopic age of black rock series samples acquired in the step 1; 3, judging the phosphorus content of the black rock series sample; 4, judging mineralization elements of the black rock series sample; step 5, and judging the whole rock age of the black rock series sample so as to judge whether the black rock series in the sample collection area has a mining value or not. By means of the method, whether the black rock series of the target area or not can be rapidly judged, so that the prospecting efficiency in the black rock series is improved, and time and capital cost are saved.

Description

technical field [0001] The invention belongs to the technical field of uranium ore, and in particular relates to a method for quickly judging whether black rock series has uranium polymetallic mining value. Background technique [0002] Black rock series are important ore-hosting formations of rare metals, non-metals and oil and gas source rocks in my country. Common ore-forming elements include platinum group elements, rare earth elements, phosphorus, vanadium, nickel, molybdenum, uranium, gold, silver, manganese, etc. There are more than 30 types of elements, and black rock series are widely distributed in my country, such as Qinghai, Xinjiang, Tibet, Inner Mongolia in the north, Guizhou, Hunan, Guangxi, Zhejiang, Jiangxi, Anhui and other provinces in the south. But not every genetic type of black rock series in every area contains mineral resources, so it is very efficient to use traditional geological prospecting methods to select areas with better ore-bearing properties i...

[0002] Black rock series are important ore-hosting formations of rare metals, non-metals and oil and gas source rocks in my country. Common ore-forming elements include platinum group elements, rare earth elements, phosphorus, vanadium, nickel, molybdenum, uranium, gold, silver, manganese, etc. There are more than 30 types of elements, and black rock series are widely distributed in my country, such as Qinghai, Xinjiang, Tibet, Inner Mongolia in the north, Guizhou, Hunan, Guangxi, Zhejiang, Jiangxi, Anhui and other provinces in the south. But not every genetic type of black rock series in every area contains mineral resources, so it is very efficient to use traditional geological prospecting methods to select areas with better ore-bearing properties in such a wide-distributed black rock series. At the same time, it will cause a lot of loss of manpower, material resources and exploration funds
