Lime slurry ph
NettetLime slurry is more alkaline, having a pH of 12.5 while limestone slurry is roughly neutral. A lime-based system will therefore add more lime when the pH drops below 12 and a limestone-based system will be controlled around 7. Unless one or the other is added, the SO2 gas will quickly drive the pH acidic. Nettet1. des. 2024 · Some make-up lime may also be added to the cyanidation tanks for minor pH adjustment to maintain the target pH during cyanidation. Some plants perform milling in circumneutral pH (or the prevailing pH according to the water source) and add slaked lime slurry only to the cyanidation section.
