Popis: | The present study presents the effect of pH reduction in iron ore slurry for an iron ore filtration process. A reduction on moisture content and increase on filters throughput was proposed by the pH modification. The experimental procedure included bench scale tests and industrial scale up of the observed results. Additionally, Langelier’s saturation index was applied to determine the optimum pH range for the filtration operation. The calcium carbonate deposition test was developed and evaluated in the present study. A comprehensive evaluation at different pH ranges was performed leading to identify the calcium carbonate deposition critical point. |
