Milling. Uranium milling involves extracting uranium from mined ore. The ore is crushed into sand size particles and the uranium is leached out. The uranium then is precipitated out of the leaching solution and dewatered, dried, and packaged. Through the extraction process, uranium is concentrated into a product referred to as "yellowcake."
Today we will discuss about difference between up milling and down milling.

When the ion milling begins, secondary Cu ions are detected by the SIMS detector as having a significant intensity. As the milling process starts to punch through the Cu top layer and into the SiO2, the intensity of Cu starts to diminish and the presence of SiO2 is first detected and then starts to increase substantially.
