Synopsis

The main objective of this work is to extract the Cadmium contained in the phosphate ore of Djebel Onk by chemical means (acid leaching). Firstly, we tested a certain number of extracting agents in order to choose the most effective. The results obtained show that among the different agents used, hydrochloric acid gives the highest extraction rate. This result is even more interesting knowing that this extractant is used in the manufacture of phosphoric acid. To this end, the study is oriented towards two objectives. On the one hand, the recovery of cadmium and on the other hand the production of phosphoric acid.
