MODULE 2.0: URANIUM RECOVERY
location of the ore is determined using Geiger-Müller counters th at are calibrated to indicate the uranium content of the rock. The ore is removed using large backhoes or front-end loaders. It is then loaded into ore trucks for transport to a stockpile at a mine or mill. Overburden is backfilled into previously mined areas for reclamation.

Fact sheet: uranium mining and milling
Milling is a process to separate the uranium from the other metals and minerals in the rock, and to collect the concentrated uranium ore. The product is a fine yellow powder known as yellowcake, which is the basic raw material for manufacturing nuclear fuel. Even in the richest ore deposits, uranium makes up less than 20% of the total rock. In
