Metallurgy Of Carbon Steel
Carbon forms compounds with other elements called carbides. Iron Carbide, Chrome Carbide etc. Cementite Unlike ferrite and austenite, cementite is a very hard intermetallic compound consisting of 6.7% carbon and the remainder iron, its chemical syol is Fe 3 C. Cementite is very hard, but when mixed with soft ferrite layers its average hardness is reduced considerably.

The Metallurgy of Cyanide Gold Leaching – An …
The carbon has a very high affinity for the aurocyanide complex and adsorbs the gold out of solution resulting in very high loadings on the carbon (typically 1000-4000 g/t). At the end of the leach the loaded carbon is removed from the slurry and the adsorbed gold is stripped out at high temperature and pressure with sodium hydroxide and cyanide solutions to form a high value electrolyte solution.
