what is ore milling or processing

Uranium Mining Overview

Milling and processing Conventional mines have a mill where the ore is crushed and ground to liberate the mineral particles, then leached in tanks with sulfuric acid to dissolve the uranium oxid The solution is then processed to recover the uranium With some South African uranium recovery from gold tailings, a pressure leach is necessary.

The Mining & Milling Process

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".
