Problems solved by technology

Although previous studies on the mineralogy, rare earth and carbon-oxygen isotopes of calcite in antimony deposits have been carried out, there is almost no research on calcite as a key indicator mineral for ore prospecting in such deposits. Systematic comparison of mineralogy and geochemical characteristics of sub-calcite, and no prospecting method for antimony deposits using calcite as a key mineral prospecting marker

Embodiment 1

[0037] The macroscopic color characteristics of the calcite developed in the surface, tunnel and drilling of the antimony deposits in the Devonian in Dushan County, Guizhou Province were classified according to the macroscopic color characteristics, and the impure milky white calcite (RGB is 238 , 238, 245) collect systematically according to the distribution, mark the coordinates of the sampling points, and take pictures of the sampling locations;

[0038] The obtained calcite samples were observed for cathodoluminescence, and calcite (RGB is 157, 38, 48) with cathodoluminescence was found, and detailed mineralogical observations were carried out;

[0039] Rare earth geochemical indicators: After field and indoor screening of calcite, conduct rare earth element geochemical analysis by solution method or LA-ICPMS micro-area in-situ method, obtain rare earth element composition data, and perform standardized distribution diagram of rare earth element chondrites to determine Rar...

Abstract

The invention discloses an ore prospecting method for prospecting an antimony ore by using calcite. The ore prospecting method comprises the steps of field screening, indoor screening, identificationof calcite rare earth element geochemical indexes and carbon-oxygen isotope geochemical indexes, establishment of a calcite antimony ore prospecting geochemical index system, drawing of an abnormal graph to guide antimony ore prospecting and the like. The method can be used for rapidly guiding antimony ore deposit prospecting prediction and improving the ore prospecting efficiency, can also be used for an antimony ore deposit mineralization fluid migration path and pointing out the prospecting direction, and has very high application and popularization value. The problems that in an existing exploration technology, the exploration period is long, the exploration investment is high, and the prospecting risk is large are solved, and economy and high efficiency of antimony ore deposit potential evaluation and ore right decision making are achieved. Meanwhile, the aspect is also one of important ways for realizing green exploration, and the ecological environment problem possibly caused inthe implementation process of the traditional exploration technology is solved.

Description

technical field [0001] The invention belongs to the technical field of mineral resources prospecting, and in particular relates to an ore prospecting method using calcite to find antimony ore. Background technique [0002] The Clark value of antimony (Sb) is 0.2×10 -6 , is a rare metal element, known as rare metal abroad, and is classified as non-ferrous metal series in my country. This element has a wide range of uses in the fields of metallurgy, chemical industry, electronics and materials, and has high economic value. The distribution of global antimony ore resources is very uneven, mainly distributed in the circum-Pacific antimony ore belt, the Mediterranean antimony ore belt, the Central Asian antimony ore belt and the Transbaikal antimony ore belt. In 2011, the United States Geological Survey released a summary of world mineral resources, showing that the global antimony reserves are about 1.8 million tons, mainly distributed in China and Russia, among which China ac...
