Phosphogypsum Technology with the Extraction of Valuable Components

Practically all phosphorites contain impurities whose presence is undesirable in fertilizers. At the same time it is necessary to extract rare earth elements from phosphorites. Every year millions of tons of phosphogypsum are sent to waste dumps that have an adverse impact on the environment. None of directions for reprocessing of phosphogypsum has been implemented in the industry yet. The paper presents the results of studies aimed at implementing the steps to obtain environmentally friendly waste from the production of fertilizers
