AB - The re-crystallization process for recovering granular crystalline gypsum from phospho-gypsum have proposed.
The process consists of two stages; at the first stage, needle-like fine gypsum is recovered with under-product of 325 mesh wet screening after the speedy hydration of dehydrated phospho-gypsum, and at the second stage, granular crystalline gypsum is recovered with upper-product of 325 mesh wet screening after dehydration and re-crystallization of the needlelike fine gypsum in Na2SO4 solution. This paper is mainly focused on the influence of dehydration time, cooling speed of temperature and re-crystallization temperature on the recovery of granular crystalline gypsum. And the re-crystallization velocity of needle-like fine gypsum at room temperature and the variation of Ca 2+ concentration of gypsum slurry during over all re-crystallization process were also discussed.
