Working Principle
The flotation machine agitates and aerates ore pulp with reagents, generating bubbles through impeller rotation. Target minerals selectively attach to bubbles and rise to form froth for skimming, while gangue minerals discharge as tailings. This process efficiently separates 0.01-0.5mm valuable minerals (Cu/Pb/Zn/Au etc.), achieving 85-95% recovery rates.
Advantages
![]() | ![]() | ![]() |
As the core mineral processing equipment, flotation machines offer five key benefits:
High-Efficiency Separation: Precisely recovers 0.01-0.5mm particles with 85-95% recovery for Cu/Au etc., 30%+ more efficient than gravity separation;
Material Versatility: Handles Cu/Pb/Zn/Au/P ores through reagent adjustment for complex compositions;
Smart Control: Online monitoring and auto-reagent dosing optimize bubble size/pH, improving stability by 40%;
Energy Saving: Frequency conversion + optimized impellers cut energy use by 25%, with 90%+ water recycling;
Modular Design: 0.5-300m³ cell volumes support parallel/series configurations for any plant scale.
