Selective leaching kinetics of low-grade calcareous ...

Lar Mountain is a low-grade phosphate ore with high carbonate content. It has about 81 million tons of phosphate ores reserves and is the largest phosphate deposit in Iran (Malak zadeh and Sarafi, 1988). This ore contains high amounts of calcareous material, therefore it cannot be used directly for acidulation processes in the industry.
