In this manuscript we present, in detail, the mechanism of the selective dissolution of calcite from low-grade phosphate ores (Epirus area, Greece) by dilute acetic acid. It was found that mass transfer makes a significant contribution to the rate-determining step of the overall reaction of four sep
