The coarse grain is a typical feature with a grain size of 10–28 mm. Fine-grain veins of quartz are interspersed throughout the fluorite. Fluorite is interlaced or cemented by later silicified veins or fluorite in stage I. Fluorite, quartz, chalcedony, opal, and other minerals are found in stage II fluorite ore. ... The surrounding rocks of ...

On the basis of geological features and effectiveness of different methods, the optimum combinations of ore prospecting techniques are proposed for the exploration of zonal type and burial type concealed fluorite ore bodies. ... The integrated exploration model is verified to be a powerful tool for prospecting concealed fluorite ore bodies in ...

The Illinois-Kentucky ore district hosts the largest deposits of fluorite in the USA. A long-standing hypothesis for the formation of the Illinois-Kentucky deposits is that the ore fluid was a sedimentary brine infused with F-rich fluids exsolved from Permian ultramafic magmas. This ore fluid may have had a F concentration between 680 and …

The article presents experimental research into intensification of fine-disseminated carbonate-fluorite ore flotation by adding FLOTOL-7,9 agent. It is shown that the optimal agent modes allow the yield of the saleable fluorite product of above 90% CaF2 grade at higher than 60% fluorite extraction.

Describe the feature you'd like. A fluorite block. Describe alternatives you've considered. No response. Additional context. Fluorite ore behaves similarly to redstone ore, and yet has no storage block. This makes mining it a pain (it fills up storage fast), so I think it would be really helpful if a block version of it existed.
