    Abstract: A method to operate a flash calcination unit with both atmosphere and temperature control is described for mineral processing requirements and other atmosphere controlled processes. The method can be used to process phosphate, gold ore or activated carbon. The critical steps of the method involve an initial mixing of fine material combined with stoichiometric burning using at least one staged combustion furnace in a vertically oriented suspension calcination furnace. This effects control of oxygen or atmosphere in the combustion furnace with attendant control of temperature in that furnace.
