Kidney ore was not uncommon and specimens of hematite pseudomorphing fluorite are known from here. Stank The first shaft was sunk in 1871, the mine eventually proving to be quite a substantial undertaking with two and a half million tonnes of iron ore being produced up to 1885.

Read Morefluorite has a hardness that is quite consistent, he chose it as 4 on his 1-to-10 scale Remember, minerals on the Mohs hardness scale do not increase in hardness by a factor of 1 each time. Fluorite, for example, is many times harder than mineral No. 3, calcite, just as mineral No. 5, apatite, is many times harder than fluorite.

Read MoreAnother shaft 3m deep was sunk on fluorite 24m to the west of the old shaft. A sample of several tonnes of hand-picked ore contained 93.1% CaF₂. The fluorite is commonly extracted in large, bright-green masses, free from impurities. Both the fluorite and wolframite are very pure and the fluorite could be used for enamelling purposes.

Read MoreFluorite is a calcium fluoride mineral that forms in cubic or octahedral shapes. It's very easily identifiable and one of the only minerals that has four directions of perfect cleavage that break into pieces with the shape of an octahedron. It can also occur in hydrothermal veins (hot water rising from underground sources) which can be seen with minerals such as Quartz, Calcite & Barite.
Read MoreFluorite commonly forms in veins and cavities of rocks. It's deposited by hydrothermal processes and often forms in association with metallic mineral deposits. For this reason, it is considered a "gangue mineral", meaning it forms around valuable minerals in an ore deposit, though in that setting, it is considered a commercially worthless mineral.
