Fluorine compounds are essential in numerous chemical and manufacturing processes. Fluorspar is the commercial name for fluorite (isometric CaF2), which is the only …

Fluorite has been attracting the attention of gemstone mineralogists because of its rich color and excellent fluorescence properties. This paper studied fluorite with three color types (blue, green, and white) and five blue-purple fluorites with an alexandrite effect. Through the study of their structure, composition, and spectral characteristics, the …

In 2019, mining's contribution to total exports for mineral products is US$4.62 billion, which is 6.6% of the total exports of the Philippines. Additionally, large scale metallic mining contributed P130.1 …

Impacts of Mining. We have found mining can negatively affect people by: Mining can impact local communities both positively and negatively. While positive impacts such as employment and community development projects are important, they do not off-set the potential negatives. forcing them from their homes and land.

Since it forms primarily from evaporation, halite normally is found with other evaporation-associated minerals such as calcite, gypsum, anhydrite, and sylvite. Sylvite, although rare, is poisonous - so it is a good idea to use your finger to test an unknown sample's taste, rather than directly licking the sample.

extent of fluorite mining on topography; assess the rate of change on the land cover in the fluorite mining environment and establish the amount of materials generated over a given period of time. The scope of the study area was approximately 7000 acres covering the mining lease area and some areas outside the lease.

Fluorine is a relatively soluble and highly reactive found within fluorite. Exposure to the chemical can lead to a severe bone disease called skeletal fluorosis, which weakens bones.
