Laboratory Flotation Machine
Flotation utilizes the fact that the metalliferous ore particles, and the gangue minerals have different interactions with water. Fundamentally floatation relies on the fact that hydrophobic ore particles and hydrophilic gangue particles can be separated. Hydrophobic means water fearing and hydrophobic substances fundamentally repel water. …
