Abstract
The phase composition of phosphorites from the Polpino deposit (Bryansk oblast, Russia) is studied. The phosphorites are shown to be highly likely to contain α-quartz, phosphate substance, and clay mineral phases, in addition to the two major phases. The textural characteristics of Polpino phosphorites are determined as dependent on the temperature of preliminary heat treatment. The behavior of impurities upon hydrochloric acid decomposition of Polpino phosphorites is investigated. Iron and aluminum impurities are found to not interfere with the acid extraction of the phosphate substance.
