摘要: A method for providing effective mercury release control during gypsum calcination is disclosed. The method comprises providing a reactor and gypsum containing mercury; providing a mercury sorbent, such as activated carbon and/or derivatives thereof in the reactor; and calcining the gypsum in the reactor to form stucco. The mercury contaminant present in the gypsum is sorbed by the mercury sorbent during the calcination process. The mercury content of the stucco is substantially similar in amount to the mercury content of the uncalcined gypsum.
