Abstract. The annual consumption of phosphate rock approached 150 million tons. The marketable phosphate is usually 30% P 2 O 5 or higher. The run-of-mine material is mostly of lower grade which needs processing or upgrading. The processing techniques of phosphate ores depend mostly on the type of associated gangue minerals present in the mined ...
