Chrome plating is an electrolytic process that can be applied to regular steel, stainless steel, aluminum, and other materials.

Chromium Ore

Studies on solid-state reduction of chromite have shown that the iron oxides get reduced more readily than the chrome oxides. Under such conditions, iron forms only one carbide Fe 3 C, which can dissolve chromium to form a complex carbide (Cr,Fe) 7 C 3. Thus, an ore rich in iron oxide will have high reducibility at relatively low temperatures.Ferrochrome Smelting In Zimbabwe - SAIMM2011-9-13 · 3. Ferrochrome Smelting Process 3.1.Raw Materials 3.1.1.
