Calcination of topaz ore in a rotary kiln

Calcination Of Topaz Ore In A Rotary Kiln Pole Tests were conducted to determine the value of calcining and defluorinating raw topaz fifteen tons of minus 1in topaz ore were calcined in a 25ft rotary kiln of 20in in inside diameter at 2600 to 2950c with feed rate of 200 to 400 1b per hour and feed retention in the kiln of 70 to 120 minutes
