System and methods for removing impurities from phosphogypsum and manufacturing gypsum binders and products
Methods and systems that remove impurities from phosphogypsum (PG), including from radium and heavy metal salts, and produce gypsum binders and products. In one embodiment, PG is reacted with a chloride solution in an acidic environment under mechanical manipulation and/or heat followed by galvanic and/or zeolite absorption removal of impurities.
