In Japan, almost no natural gypsum is mind for industrial uses, and almost all gypsum is synthetic gypsum, that isdesulpho-gypsum, produced by waste sulfur dioxide gas from metal smelters, power plants and other industrial waste sources. The amount of such synthetic gypsum production has reached more than six million metric tons per year in 1979. Major uses are for cement and building material. Other uses are for soil conditioner, investment casting mold, organic composite materials, etc. and sulfur recovery by gypsum decomposition is being examined. This paper summarizes present Japanese stajs and new application of synthetic gypsum produced from desulphowaste gas.
