Where I can farm tellurium?
1.7k. Posted December 5, 2020. There is no easy way to get Tellurium. You can get 1 occasionally from archwing missions, even the low Earth ones, but expect it more as a siurprise than a farming location. The other place is Uranus survival mission, and even there, its stupidly rare.

Tellurium Assay Determination
Subtract 0.1 milliliter for a titration blank, and calculate the amount of tellurium present. A reading of 0.3 milliliter is equivalent to 0.1 milligram tellurium or 10 parts per million (0.001 percent) in a 10-gram sample. This amount of tellurium is considered to be the minimum concentration that can be determined reliably by the …

How to Farm Tellurium in Warframe | Attack of the Fanboy
Tellurium can be found as a bounty reward from Tier 4 difficulty or higher in Fortuna, archwing missions, and sabotage caches. However, it's best to farm it from the survival mission node, Ophelia, on Uranus. While the Uranus planet drop tables do not show Tellurium, this mission is considered a "submersible", meaning that there is an ...
