In the past two and half decades mining activities of fluorspar have been operational in the southern part of the Keno Valley. However very little socio-economic and environmental studies have been conducted to establish the concomitant effects of fluorite mineral development in the Valley.
Mining of the mineral, which is predominantly used in chemicals such as hydrofluoric acid and fluorocarbons, began in the 1920s and has continued ever since, being able to take advantage of the rich seams that run though the area. In 2012, British Fluorspar reopened the Cavendish Mill mines, which now produce 65,000t per annum of fluorspar.
Fluorine compounds are essential in numerous chemical and manufacturing processes. Fluorspar is the commercial name for fluorite (isometric CaF2), which is the only fluorine mineral that is mined on a large scale. Fluorspar is used directly as a fluxing material and as an additive in different manufacturing processes. It is the source of fluorine in the production of hydrogen fluoride or ...

South Africa has an abundance of mineral resources, accounting for a significant proportion of world production and reserves, and South African mining companies are key players in the global industry. As a global player, it is important that the industry is well positioned as an investment destination through policies that ...
All mining works are doing by trenches (Figure 1 and Table 1). 7) The Njakh mining area. The last studied mining area is the Njakh mine (GPS coordinates: 31.41˚N, 3.91˚W). 30 km at the east of Erfoud city, the mineralization is mainly barite with small amounts of fluorite.
Mining has played a part in the economic development of developed countries such as the USA, Canada and Australia. However, the mining economic growth connection varies considerably from that claimed in the historical analogy reasoning. It is not evident that these countries' historical experience applies to modern developing nations due to modifications in the nature of the world …
The St. Lawrence Fluorspar Mines: A Brief History. St. Lawrence is located on the southeast coast of the Burin Peninsula. Until the early 1930s, the people of the area survived mainly through a combination of inshore fishing, small-scale farming, and other traditional activities. A tidal wave devastated the area in 1929; 27 people lost their ...

The social and economic impacts of gold mining 70 % of total expenditures by gold mining companies are on payments to suppliers, contractors and employees.
The mining industry is involved in the extraction of precious minerals and other geological materials. The extracted materials are transformed into a mineralized form that serves an economic benefit to the prospector or miner. Typical activities in the mining industry include metals production, metals investing, and metals trading.

Globally, Mexico is second in the production of Fluorite with a confirmed 1,032,240.69 tons produced in 2006 and this number has gone up as the country continues to modernize its mining industry. For a long time, Mexico has been producing an average of 18% of the total global production of the mineral, a figure that has been increasing annually.
Fluorspar is found in a variety of geological environments on every continent veins and as deposits from hot gasses, and it is mined either as a main commodity or as a co-product of metal mining. It contains 51.1 percent calcium and 48.9 percent fluorine. Studies have shown that fluorspar is very easy to
