Mineral firing characteristics of multi-stage furnace
For minerals with slow reaction rates
It is suitable for the roasting process of slurry feed and slow drying
Solid materials can be exposed to many different reaction temperatures and atmospheres during the roasting process
The residence time of the mineral material in the furnace can be flexibly adjusted
Compared with the rotary kiln, the temperature distribution and atmosphere change in the furnace can be easily controlled, and the product quality is stable
It can be operated under the conditions of softening, sintering and melting of solid materials.
Applicable examples: recovery of tungsten and vanadium from molybdenum ore, magnesium oxide calcination, uranium ore, laterite nickel ore, steelmaking waste slag
