The results of this study revealed that column flotation technology is a promising tool for beneficiation of calcareous phosphate ores. A high purity ore of 35% P 2 O 5 can be easily achieved at a high recovery value of 95% starting from a rock contains 25% P 2 O 5, high calcite content (52.7% CaO) and CaO:P 2 O 5 ratio equals 2.1.
