Hydrothermal processes in the Fen alkaline-carbonatite
Rocks of the Fen complex have been exploited for various resources over the last 400 years. Historical mining for hematitic iron ores from the “red-rocks” (rødberg) at the Gruveåsen mining hill took place from the 1650-ies until 1927, and later (1953 to 1965) Nb was mined from søvite in the Søve and Tufte areas (Dahlgren, 2006).The REE The visual identification of the fluorite-quartz (stage I according to Haschke et al. 2021) and haematite-barite and barite-fluorite (stage II according to Haschke et al. 2021) assemblages during ongoing underground mining is mainly based on the scheme for vein-type mineralisation in the central Erzgebirge introduced by Kuschka et al.,whichRapid ore classification for real-time mineral processing

Barite was first Mining Association of Nova Scotia
The ore was carted around the southern end of Lake Ainslie, which is the largest freshwater lake in Nova Scotia, to Whycocomagh for shipment via Ainslie Glen. The carting costs two dollars per ton. There were years when Lake Ainslie’s barite mining was the only barite production in Canada. Production statistics from 1904-20 show that NovaBarite, used in mud formulation, is mined in several places to support the industry. However, there is insufficient literature on the downside of mining and associated hazards, especially in the artisanal barite mining sector. This paper contains three parts.

Barite : Properties, Formation, Uses and Mining Localities
Thailand: Thailand has barite resources in several regions, and it is a minor producer. 11. Nigeria: Nigeria has substantial barite deposits in states like Benue, Cross River, and Nasarawa. 12. Peru: Peru also has barite deposits, and mining activities occur in regions like Huánuco.The minerals barite (BaSO4, barium sulfate) and witherite (BaCO3, barium carbonate) are the common sources of barium and its compounds needed for many industrial processes and products. Barite, the principal ore mineral, is found the world over and is abundant and widely distributed throughout the United States.Barite Resources of the United States USGS

Barite is the primary ore of barium, which is used to make a wide variety of barium compounds. Some of these are used for x-ray shielding. Barite has the ability to block x-ray and gamma-ray emissions. Barite is used to make high-density concrete to block x-ray emissions in hospitals, power plants, and laboratories.Barite (BaSO 4) is a widespread mineral in deep-sea sediments, varying between 1% and 10% by weight on a carbonate-free basis.It is the predominant Ba phase in the ocean. BaSO 4 is known to compose a solid solution series with SrSO 4 as celestobarite in the skeletal portions of some marine organisms (i.e., the Xenophyophoria) and is often found in Barite an overview ScienceDirect Topics

Carbonatites: related ore deposits, resources, footprint, and
Ground radiometric and magnetic methods are useful for follow-up surveys. A variety of geochemical (e.g. stream-sediment, soil, and till chemistry; ‘direct indicator minerals’) and biochemical methods have been successfully used, tested, or customised for exploration and detection of carbonatites and related deposits.
