Chromium metal by the reduction of Cr 2 O 3. This is obtained by aerial oxidation of chromite in molten alkali to give sodium chromate, Na 2 CrO 4, which is leached out with water, precipitated and then reduced to the Cr (III) oxide by carbon. The oxide can be reduced by aluminum (aluminothermic process) or silicon:

The main electrolytic method used for the production of large tonnages of chromium metal is the chromium (III) or trivalent chrome-alum bath electrolyte method. This process was developed by the U.S. Bureau of Mines in 1950, following a long-term study on chromium-metal electrowinning.

Ligands of this type are also often called chelating (chelos-claw) ligands. Three acac ligands are therefore needed to complete the octahedral coordination about the central metal ion, giving formula [M(acac)3]n+.
