A significant benefit of Abu-Tartur phosphate rock processes for the recovery of the lanthanides lies in their relatively high content of lanthanides (averaging 0.2%., while the produced fertilizer would pollute the environment less with radioactive materials due to the low uranium content (averaging 25 mg/kg) [8].

The results indicated that heavy metal content was low in Abu Tartur phosphate compared to imported rock and was below the permissible limits with the ex-ception of lead which was higher in local phosphate de-posits than the imported rock samples. Phosphate rock is a source of heavy metal pollution (air, soil, water, food chain, etc.) therefore requires removal from the rock prior to its use ...
