Based on the process mineralogy study, an experiment was performed on flotation of a phosphogypsum from Hubei Province for its purification. The experiment was run in stronger acid solution with T-609 as the collector, by adopting a process consisting of one roughing, one scavenging, and two cleaning, resulting in the final cleaning concentrate with the content of calcium sulfate dihydrate over 99%, with a whiteness of 75% at 200 ℃. It is shown that this processing flow is characterized by simplicity, high separation rate of phosphogypsum, less addition of agent. The obtained product, with low content of impurities, is up to the special grade in the national standard for gypsum, and can be used for preparation of high-end building materials and gypsum whiskers.
