The market demand for fluorite has been growing, and fluorite has become a strategic mineral in China. With the exhaustion of fluorite resources in the main producing areas (Zhejiang, Hunan, etc.), the barite fluorite deposit has been paid more attention and utilized in Wuling Mountain area (the adjacent place of Chongqing, Guizhou and Hunan).

As a rare and non-renewable strategic non-metallic mineral resource, fluorite has been widely used in many fields such as national defense, chemical industry, metallurgy, optics. Fluorite resource reserves are abundant in China, but there are many lean ores with complex composition and low recovery. This study summarizes the …

The optical absorption spectra of yellow fluorite crystals from hydrothermal barite–fluorite veins of the Erzgebirge, eastern Germany, are characterized by a broad absorption band with a peak at 433 nm that shows a subtle vibronic structure.

Figure 1. Mining districts containing barite and fluorite in New Mexico. Barite and fluorite are critical minerals because these commodities are mostly imported from other countries. Barite (BaSO 4) is a heavy, nonmetallic material containing 65.7% barium oxide (BaO) and 34.3% sulfur xide (SO 3) and crystallizes in flat crystals having lateral dimensions …

Fluorite and barite samples which sourced from a mine in Pengshui County, Chongqing were utilized as the subjects of this study. The chemical compositions of samples are presented in Table 1, revealing the content of CaF 2 in fluorite is 96.56 % and that of BaSO 4 in barite is 94.26 %. Based on the results obtained from X-ray diffraction ...

A method for separating a calcite-rich low-grade fluorite barite paragenic ore, includes the following steps: S1, crushing; S2, performing classification on a crushed ore to obtain a fine-grained ore, a medium-grained ore and a coarse-grained ore; S3, performing jigging gravity separation on the medium-grained ore and the coarse-grained …

The barite–fluorite metallogenic belt in southeastern Sichuan is one of the most important barite–fluorite ore‐concentrated areas in China. In order to find the ore‐forming source and the mineralization age of the Fengjia and Langxi barite–fluorite deposit, we systematically evaluated the rare earth element (REE) contents and isotopic …

The central Yangtze Block is one of the main fluorite-producing areas in China, with more than 300 Ba-F deposits in this region of approximately 20,000 km 2.Some of the deposits are very large, such as the Fengjia and Langxi Ba-F deposits (Zou et al., 2017), with substantial reserves of fluorite and barite (Fig. 2 b, Yan et al., 2016).Over …
