BANKING AND CREDIT NEWS-19 May 2010-ICRA rates Saurashtra Calcine Bauxite and Allied Industries bank facilities at LB+(C)1994-2010 M2 COMMUNICATIONS http://www.m2.com

The calcine process applies heat (above 1400F) to the sand long enough to "dead burn" the sand's clay component, breaking its adhesion so clay can be separated from the sand grains.
These systems do not reach a temperature high enough to calcine the clay used with green sand and, therefore, are only suitable for organically bonded sands.
In all cases, the goal was to be able to treat the sand at the higher temperatures 1300-1600C or 2372-2912F) required to calcine or kill the clay in the clay-bonded sand.
