Beneficiation of Abu Tartur phosphate rock by leaching
4. Conclusions. Abu Tartur phosphate rock can be beneficiated by leaching it with dilute acetic acid. This is due to the fact that dilute acetic acid used in leaching has the ability to react with the calcium carbonate impurity found in the phosphate rock while its attack on the tricalcium phosphate is small.
