Fluorspar Deposits 1982

Weardale Steetley Minerals Rock Site

Much development work to find new deposits was carried out by SAMUK but In 1982 all mining interests in fluorspar came into common ownership when Minworth Ltd. took over those interests and also those of BSC. Minworth concentrated their efforts on Frazer’s Hush and Cambokeels Mines with a processing plant at Broadwood. The company expanded rapidly buying a fluorspar mine in Canada and worked

Fluorite Wikipedia

One of the largest deposits of fluorspar in North America is located in the Burin Peninsula, Newfoundland, Canada. The first official recognition of fluorspar in the area was recorded by geologist J.B. Jukes in 1843. He noted an occurrence of "galena" or lead ore and fluoride of lime on the west side of St. Lawrence harbour. It is recorded that interest in the commercial mining of fluorspar

History of Mining in the North Pennines Fluorspar

The mining of non-metallic ores fluorspar, witherite, and barytes (commercial barite ore pronounced “bear-eye-tease”) in the Northern Pennines began about the time lead and iron mining were in serious decline. Previous to the advent of modern open-hearth steel-making techniques there was little demand for fluorspar as a commercial commodity, and most fluorite produced from the Weardale

Fluorite Mines in the North Pennines Rookhope Fluorspar

Fluorspar deposits on both veins proved quite rich and the mine was to become one of the top fluorspar producers in the region during the latter part of the century. With the collapse of British Steel in the early 1980s the mine was acquired by Weardale Minerals and Mining, whose parent company Minworth, Ltd. was itself forced into receivership in 1991. The mine was then purchased by Sherburn

In the mid-1970s, the U.S. fluorspar mining industry began to decline because of foreign competition. By 1982, there was essentially only a single U.S. producer left, and that company ceased mining in 1996. Consumption of fluorspar in the United States peaked in the early 1970s, which was also the peak period of U.S. steel production. Since then, U.S. fluorspar consumption has decreased

With depletion of high-grade deposits, production must depend upon low-grade deposits that are highly contaminated with impurities which may be silica, calcite, barite, iron oxide, and sulphides such as pyrite, galena, and sphalerite, in close association. The flotation problem is largely one of impurity removal. The sulphide minerals are generally

the size and purity of the fluorspar deposits became for the first time adequately appreciated. There has since been an active and intelli­ gent campaign to widen the market for spar and to increase its pro­ duction. Incidentally some lead and zinc is being found and mined, though so far no important bodies of either have been developed in the Illinois portion of the district. PREVIOUS

Whiteheaps Fluorite Mine information and photos

Later on, a treatment plant was built and the fluorspar mining seems to have come from the reworking of stopes around the Whiteheap Shafts. When British Steel took over the site in the mid 1960's the mill was rebuilt to include a floatation circuit and the Whiteheap site was further developed. Finally in 1979 British Steel closed the site and a few years of inactivity followed. In 1982 the

A New Classification Scheme of Fluorite Deposits

Fluorite deposits occur in a variety of geologic environments throughout the globe. It may occur as the main or only economically recoverable ore mineral in deposits or may present as the accessory gangue minerals with other ores. It is therefore necessary to understand various genetic types of the fluorite deposit. The present paper synthesises the information of some of the known fluorite
