| 1. | Calcination involves passing the waste through a heated, rotating tube.
|
| 2. | After calcination the flint pebbles were milled to a fine particle size.
|
| 3. | Usually a high temperature calcination step is required to eliminate organics remnants.
|
| 4. | The ore was pre-processed by calcination for which special kilns were built.
|
| 5. | The calcination reaction is the only endothermic reaction in the process and is shown here:
|
| 6. | The heat necessary for calcination can be provided by oxy-combustion of coal below.
|
| 7. | The mineral substances of bone may be obtained by calcination, which destroys the organic matter.
|
| 8. | The advantage of this method is to get crystalline particles or films without postannealing and calcinations.
|
| 9. | Calcination is an endothermic process and as such requires the application of heat to the calciner.
|
| 10. | The first stage is the calcination of the bauxite at 1200 �C with sodium carbonate and coke.
