The ore is crushed and sent through the mill, where extraction processes concentrate the uranium into uranium‐oxygen compounds called "yellowcake." The mill tailings are the fine‐grained, sandy waste byproduct that remain after the milling process extracts and concentrates the uranium from the ore.احصل على السعرWhatsApp
Conventional Uranium Mills |
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.احصل على السعرWhatsApp
