Process Configuration
Flotation Process Flow Options
The XJM Series supports two primary flowsheet configurations to suit varying coal beneficiation plant requirements one time flotation for standard applications and secondary flotation for maximum coal essence recovery.
One-Time Flotation Process

Industry Applications
Applications in Coal Slime Flotation & Mineral Processing
The XJM Series is optimized for domestic coal beneficiation flotation lines where performance is required from both primary and secondary flotation stages.
Coal Slime Flotation
Recovery of ultra-fine coal particles from the effluent of coal washing plants. Particularly effective for flotation machines for coal slime applications in domestic coal preparation lines.
Fine Coal Flotation
Treatment of fine coal fractions (<0.5 mm) that cannot be efficiently processed by gravity-based methods, recovers clean coal essence from tailings streams.
Coal Washing Plants
Integration into coal washing plant flotation circuits as primary or secondary froth flotation units improves overall clean coal yield and reduces waste to tailings.
Mineral Flotation
Applicable to nonferrous metal ores, sulfide minerals, and industrial mineral flotation where precise particle–bubble contact and reagent efficiency are critical.
Coal Beneficiation Plants
Full-plant integration as the primary flotation stage in coal beneficiation flotation circuits, supporting one-time and secondary flotation process configurations.
Slurry Pretreatment Circuits
Works in conjunction with slurry pretreatment equipment to condition and disperse slurry ahead of flotation, improving recovery rates and reducing overall reagent consumption.
