Gold extraction - Wikipedia

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold …

Milling and Processing - How Uranium Mining Works | HowStuffWorks

One part of the process will separate sand and debris gathered with the ore through ion technology, while another will use a series of solvents to pick the uranium away from other parts of the ore. Throughout the milling process, remnants of other rocks and radioactive elements from the ore -- also called tailings-- are gathered to be stored away. The product will continue to undergo chemical separation until all that's left is the desired amount of uranium.
