    Leaching characteristics and mechanism of the synthetic calcium

    A calcium aluminate slag which consists only Ca 12 Al 14 O 33 phase is seen as the most leachable slag in a sodium carbonate solution compared to the other slag compositions in the CaO-Al 2 O 3 binary system. The leaching recovery may decrease with the precipitation of Al(OH) 3 in bayerite form, and Ca 3 Al 2 (OH) 12 phase. However, a “free

    This secondary dross is used for making calcium aluminate by sintering with limestone (CaCO 3) in a rotary kiln. Tests conducted by Yang and coworkers (2004) have shown that the calcium aluminate flux thus produced has high melting rate and good desulfurization capacity. It could well replace calcium fluoride as flux in steel production.
