Selective Flotation

Selective flotation is a mineral processing technique used to separate specific valuable minerals from ores by making them attach to bubbles and float to the surface, while undesired rock or waste materials sink. It involves adding chemicals called reagents that make certain minerals hydrophobic (water-repelling). By controlling the chemical environment and aerating the mixture, only the desired minerals attach to bubbles and are removed as a concentrated foam. This method allows for efficient separation of different minerals within complex ores, improving purity and extractability without excessive grinding or grinding, making the process cost-effective and environmentally manageable.
