Ruby mineral extraction methods –open pit mining techniques

They are formed mainly in high-grade metamorphic environments where hydrothermal fluids meet limestones. Rubies can also be created in a laboratory, using two different methods: Flame-Fusion and Flux-Growth. The cheapest method of producing synthetic rubies is the flame-fusion process. The chemicals are melted and dripped onto a bowl.

6.3 Fusionable Materials. Fusion fuels are all light elements, which are enormously more abundant than the heavy elements relevant to fission. Isotopic separation is fairly easy in light elements since low masses mean relatively large mass ratios (Li-7 is only one atomic mass unit heavier than Li-6, but it is 17% heavier; U-238 is 3 amu heavier than U-235, but it is only 1.3% heavier).
