Abstract
Usually, the lime sulfur (calcimum polysulfide) which is an excellent fungicide is produced from the refined sulfur and the calcium oxide. The principle of this reaction is similar to that of the sulfur ore treatment with super heated steam in an autoclave. We, then tried to prepare the lime sulfur directly from the sulfur ore treating it with calcium oxide milk in an autoclave.<BR>And we found that the lime sulfur could be successfully produced from sulfur ores by treating them with calcium oxide at the following conditions; ore size, ca. 13 mesh. Mole ratio of CaO: S=3.0: 11.5. Temp. 105-110°C. Reac. time 20-40 min. Agitation 200rpm.<BR>When the sulfur ore contains about 73.0% or more of sulfur, this method was applicable more economically than the usual method with better, recovery regardless of origin and kind of the ore. We have constructed the factory by this method, and confirmed the results mentioned above.
