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
