چکیده انگلیسی
The hydrometallurgical recovery of zinc from EAF dust is feasible with a relatively high recovery yield, while iron mostly remains in the solid phase. Calcium, too, is transferred to the solution with a relatively high recovery yield. This results from the use of a low concentration of sulphuric acid. In such a way, it is possible to set up the conditions for the leaching of EAF dust, namely sufficient sulphuric acid concentration in order to achieve an optimum zinc yield to the solution without an iron dissolution. However, the problem is that the chemical and mineralogical composition of each steelmaking dust is individual. Therefore, it is necessary to study the processing conditions for each one of them.
