PROCESS AND PLANT FOR SEPARATING HEAVY METALS FROM PHOSPHORIC STARTING MATERIAL |
摘要 |
A process for separating heavy metals from phosphoric starting material comprises the following steps: (i) heating the starting material to a temperature of 600 to 1.200°C in a first reactor (1) and withdrawing combustion gas; (ii) using the combustion gas of step (i) to preheat an alkaline source; and (iii) transferring the heated starting material of step (i) and the heated alkaline source of step (ii) to a second reactor (20), adding an elemental carbon source, heating to a temperature of 700 to 1.100°C and withdrawing process gas and a product stream. |
