Nuclear Fuel Cycle | Department of Energy
Milling produces a uranium oxide concentrate, which is shipped from the mill. In the milling process, uranium is extracted from the crushed and ground-up ore by leaching, in which either a strong acid or a strong alkaline solution is used to dissolve the uranium oxide. The uranium oxide is then precipitated and removed from the solution.

Outdoor use of untreated aluminium
The oxide layer makes untreated aluminium more corrosion-resistant. When using untreated aluminium outdoors, a thin oxide layer is formed on the surface. When aluminium comes in contact with oxygen, an oxide layer forms, which is strongly attached to the aluminium surface. The layer protects the metal against further attacks, thereby increasing ...

What is a Mill Scale? - Definition from Corrosionpedia
Mill scale is a flaky surface that can be found on iron oxides and metals that have been hot rolled. Mill scale forms on exterior surfaces of sheets and plates as they are being manufactured through rolling steel billets and hot iron into rolling mills. Mill scale typically consists of iron oxides that are bluish black.

Chapter 6 Copper Production Technology
the Middle Ages, the oxide ores had largely been exhausted. Learning from the Roman experience with seepage, the Moors developed open pit min-ing, heap leaching, and iron precipitation tech-niques that continued to be used at Rio Tinto into the 20th century. In Britain, copper and tin were worked in Corn-wall and traded with the Phoenicians as ...
Need source for Black Oxide
5869. Likes (Received) 2277. I don't know the chemistry of that particular Caswell kit, but most of the pre-packaged small kits of "black oxide" that work at room temperature or sort-of-warm hotplate temperatures are actually a selenium-based black, which is quite different from true black oxide finish. It's not nearly as durable, for starters.
Chemical Milling of Titanium Alloys
used to chem mill titanium alloys. Because of the local concentration of hydrogen gas during chem mill process is high; hydrogen content in the post chem mill parts can cause the embrittlement of the parts. In order to remediate the effect of hydrogen, it is necessary to reduce/remove hydrogen in situ and nitric acid is used to serve that purpose.
Mill Scale – IspatGuru
Mill scale is usually removed by process water used for descaling, roll and material cooling, and by other methods. It is subsequently separated by gravity separation techniques.

During milling, the lead oxide that forms on the surface of the ingots and fine particles of un-oxidized lead are broken off, forming a fine dust that is removed from the mill by a circulating air stream. Centrifugal mills and cyclones are used to collect large particles, while the finer particles are collected in a baghouse.
Why use Different Size Balls in a Mill
In test 3, in which the grid was used to segregate the different sizes of balls, a further advantage of about 4 percent in efficiency is shown. The conical mill in test 4 increased the efficiency to 58 percent more than in test 1. The efficiency with the long (6-foot) conical mill was about the same as with the short (3-foot) one.
