CALCINATION OF TOPAZ ORE IN A ROTARY KILN * CALCINATION OF TOPAZ ORE IN A ROTARY KILN * Pole, Gordon R. 1944-06-01 00:00:00 Abstract Reports have indicated that calcined topaz might be useful as substitute material for Indian kyanite in high aluminous, mullite‐type refractories. Tests were conducted to determine the value of calcining and defluorinating raw topaz.
3D Model of a FEECO Direct-fired Kiln. Acid Roasting. Once the material has been decrepitated, or converted to beta-phase spodumene (β-form), an additional calcination step is required. The concentrate, now in β-form, is first mixed with sulfuric acid (a step referred to as sulfuric acid digestion) and fed to a separate rotary kiln.
The kiln model applied in this work was developed by Hatch over a number of years and has been used for several rotary kiln projects. It has its roots in a FORTRAN program that was developed by Venkateswaran (1978) to study the reduction of iron ore. The original software was used to model the operation of a 35 m pilot kiln at the Stellco company
