Uranium mining + milling

At a grade of 0.1% uranium, one megagram (1 Mg = 1 metric tonne) of rock has to be mined and processed to obtain 1 kg uranium in the mill. This is ten times as much as from rock at a grade of 1%, containing 10 kg uranium per Mg rock. Consequently, the mining energy input per kilogram uranium is at least ten times as large.

Conventional Uranium Mills | NRC.gov

A conventional uranium mill is a chemical plant that extracts uranium using the following process: Trucks deliver uranium ore to the mill, where it is crushed into smaller particles before being extracted (or leached). In most cases, sulfuric acid is the leaching agent, but alkaline solutions can also be used to leach the uranium from the ore.
