Feb 16, 2021 Aluminothermic or silicothermic processes used for the metallurgical production of chromium metal from chromium oxide yield a metal that may contain more than 99 percent chromium. A metal of this purity apparently meets all the requirements of the alloy industry, but the price is about three times that of chromium in the form of low-carbon ferrochrome, which indicates that the
resulting fused block is then crushed in a mechanical plate crusher into par--ticles approximately l to 2 mmin diameter. These particles are further ground in a ball mill using aluminum oxide crushing stones until the eutectlc is a fine powder. The powder is then sieved to obtain eutectlc particles which are between 44 and 70 pmin diameter.
