Mill scale, is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling hot iron or steel billets in rolling or steel mills.
It looks like a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in color.
Being produced during the reheating, conditioning and hot rolling operation for the production of steel articles, the mill scale initially adheres to the steel surface and protects it from atmospheric corrosion, provided no break occurs in this coating.
From the chemical and physical analysis performed on the scrap, and according to the european environmental rules, the material has been classified as a special non dangerous waste, listed in green list
In particular the mill scale can be classified as follows:
Einecs (european commission no.): 266-007-8
Waste code: 10 02 10
Basel code: b 12 30
Hs code: 2619.00

It is a rare and strategic metal for the electronics industry with limited substitutability.
Tantalum is a metallic element with outstanding heat resistance, high electrical capacitance and very high resistance to corrosion and chemical intrusion. This element is vital for the electronics industry. Its primary use is in the form of powder for the manufacture of capacitors used in cell phones, computers, TV screens, digital cameras and other electronic equipment. On the other hand, in the form of metal, it is used, for example, in the manufacture of jet turbine blades, missile parts and nuclear reactors.
Brazil occupies a prominent position in the world scenario of tantalite mining, either as a reserve holder or as a producer; and the medium-term outlook for the tantalite market is one of relative scarcity and significant price increases. The total Brazilian reserves represent about 68% of world reserves.

At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel.
The recovery ratio after melting in furnace for the most valuable alloy elements is:
- Ni: 3.5 - 4.5%
- Cr: 6-8%
From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows:
