A very early endeavour was the electromagnetic isotope separation (EMIS) process using calutrons. This was developed in the early 1940s in the Manhattan Project to make the highly enriched uranium used in the Hiroshima bomb, but was abandoned soon afterwards
Caultrons are mention in many other places as well. So why does official US documents not mention anything about magnets or caultrons? I am sure Anons know the answer already.
iirc, silver was used to build huge magnets that were necessary for some step of this process, not directly used in mining.
