Journal Article 2025 05 19 Flotation is a type of mineral separation process that occurs in a water-mineral slurry. The surfaces of the selected minerals are rendered hydrophobic through conditioning with specific reagents. The material used in this study was gilsonite. After the preparation of the samples, two series of with and without irradiation on gilsonite flotation experiments were designed, using the central composite design method. Finally, it was concluded that the ultrasonic method achieves a higher desired recovery amount and lower ash percentage in the concentrate than the normal method in the rougher stage of flotation. https://ijmge.ut.ac.ir/article_102447_5aae03765281f051633e02dd7de393d4.pdf
