The annual mining capacity of Xiang Zhen Mining equals to 300,000 tons and the annual ore processing capacity reaches 200,000 tons; the fluorite concentrate grade is 98%. In addition, Xinyi Fluorite Co., Ltd. (located in Jingde, Anhui Province) which is a subsidiary of Xiang Zhen Mining has the mining permits for Qingzheng Xinyi Fluorite Mine and Xinglong Guangrong Fluorite Mine. Ceramic grade fluorite (85–95% CaF 2) is used in the manufacture of opalescent glass, enamels and cooking utensils. The highest grade, acid grade fluorite (97% or more CaF 2 ), accounts for about 95% of fluorite consumption in the US where it is used to make hydrogen fluoride and hydrofluoric acid by reacting the fluorite with sulfuric acid .

Overview of geochemistry, acid generation, and metal solubility

Acid/base • Acid (mine/rock) drainage (pH 1 to 6) – One of largest water quality problems at hardrock mine sites – Starts with pyrite/fools gold in mine sources – Need water and air – Leaches more metals in mine sources – Harms drinking water, aquatic biota

Fluorite is the only mineral for which significant quantities of the important element fluorine can be obtained. Fluorite is also used as a flux in the manufacture of steel and other metals to eliminate impurities.There is a great demand for Fluorite in the optics field, and

The high grade ore from this mine was extremely rich, and additional drilling showed more and more super rich ore. The Sleeper became one of the richest open pit mines in Nevada - much of the ore was close to an ounce per ton which is rather rich for a surface mine.

Fluorite (calcium fluoride, CaF 2), known commercially as 'fluorspar', is the principal source of fluorine and fluorine chemicals, including the important industrial chemicals hydrogen fluoride (HF) and hydrofluoric acid (70% HF). Additional Reading Olliver, J.G., 1976.

Largest Acid Grade Fluorite Mine 2017-10-4fluorspar, processed fluorite, comes in several distinct grades namely acid, ceramic, metallurgical among otherscid grade fluorspar is important in the manufacture of hydrofluoric acid, cryolite, and hydrogen fluorideeramic grade fluorspar is fundamental in the manufacture of glass, enamelware, and ceramics including in decorations.

Fluorite is also used as a source of fluorine for hydrofluoric acid and fluorinated water. The element fluorine also gets its name from fluorite, fluorines only common mineral. Other uses of fluorite include an uncommon use as a gemstone (low hardness and good cleavage reduce its desirability as a gemstone), ornamental carvings (sometimes misleadingly called Green Quartz) and special optical uses.

2012/1/1At that time, Illinois was the largest producer of fluorite in the United States, but the last fluorite mine in Illinois was closed in 1995. The world reserves of fluorite are estimated at 230 million tonnes (Mt) with the largest deposits being in South Africa (about 41

FLUORITE Indian Minerals Yearbook 2012 consumption and trade, namely, the acid grade containing more than 97% CaF 2 and the sub acid grade analysing 97% or less CaF 2 The sub acid grade includes metallurgical and ceramic grades and is commonly known as metallurgical grade Fluorite production in the country is scarce At the global level, the country has less production.
