Evaluation of pyrite recovery via bench-scale froth flotation from a sulfide ore deposit in southwestern Spain
In recent decades, there has been an upsurge in focus on the extraction of pyrite from sulfide ore deposits due to its vital role in the process of metal extraction and environmental management.

| Sumario: | In recent decades, there has been an upsurge in focus on the extraction of pyrite from sulfide ore deposits due to its vital role in the process of metal extraction and environmental management. This study explores the flotation behavior of pyrite in sulfide ores using mechanical-cell flotation. This study compared the performance of two commonly used flotation collectors, potassium butyl xanthate (KXT) and diethyl dithiophosphate (DTP), in the beneficiation of a sulfide ore from southwestern Spain. Statistical analysis performed using MiniTab 4.0 revealed that collector type, reagent dosage, and pulp pH were the principal factors affecting pyrite recovery. Under the tested conditions, KXT exhibited superior metallurgical performance and selectivity compared with DTP. The flotation kinetics demonstrate that the chemical was more efficacious throughout both the rougher and cleaner phases of the process. The findings robustly corroborate the notion that employing xanthate-based chemicals to enhance pyrite concentration facilitates metal extraction from the Sulfide Ore Deposit in southwestern Spain. The study sets out a basis for process growth, and it is proposed that further research be conducted under industrial water conditions to validate the findings. |
