SF/KYF Self-Aspirating Flotation Cell High Recovery Rate for Gold Copper Zinc Ore Beneficiation
Flotation Machine (also known as Flotation Cell) is the core beneficiation equipment for separating valuable minerals from gangue. Adopting self-aspirating stirring & froth flotation principle, it uses mineral surface hydrophobicity difference to realize precise separation of target ores and impurities. Featuring automatic air suction, uniform bubble dispersion, high recovery rate and stable operation, it is widely matched with ball mills to form complete mineral processing production lines for non-ferrous metal ores.

What is Flotation Machine?
In traditional mineral processing, crushed ore powder contains mixed valuable minerals and useless gangue. Ordinary sorting equipment cannot effectively separate fine-grained target ores, resulting in serious resource waste and low ore grade. Most outdated flotation equipment has prominent defects: relying on external air supply with complex configuration, uneven bubble distribution leading to poor mineral attachment effect, easy slurry precipitation and stratification, low finished ore recovery rate, unstable flotation index and high power consumption, which greatly reduces mine economic benefits.
Our Self-Aspirating Flotation Machine thoroughly solves the above industry pain points. The optimized impeller-stator stirring structure realizes automatic air suction and slurry circulation without external air blower. Micro-fine bubbles are evenly dispersed in the pulp to fully bond with target mineral particles. Through stable froth layer separation, high-grade concentrate and tailings are accurately separated. With high separation precision, large processing capacity and low energy consumption, it has become mainstream core equipment for modern gold, copper, zinc, lead and fluorite ore beneficiation plants.
Complete Machine Configuration & Composition of Flotation Machine
1. Self-Aspirating Stirring System (No External Air Supply)
Different from inflatable flotation equipment that requires supporting fans, this flotation machine adopts negative pressure self-aspiration design. The high-speed rotating impeller forms negative pressure inside the tank, automatically sucking air down the hollow main shaft and mixing it with slurry. It saves external air supply equipment, simplifies production line layout, reduces equipment investment and failure points, and realizes integrated aeration and stirring operation.
2. Optimized Impeller & Stator Micro-Bubble Generation
Equipped with high-precision radial blade impeller and stator structure. The impeller shears air and slurry violently to produce a large number of uniform micro-fine bubbles, which increases the contact area between bubbles and mineral particles. It effectively improves mineral hydrophobic adhesion efficiency, avoids large bubble overflow and ineffective flotation, and significantly upgrades ore recovery rate and concentrate grade.
3. Full-Circulation Slurry Stirring Anti-Precipitation Structure
The unique three-dimensional circulating slurry circulation design realizes up-down and left-right full mixing of pulp in the tank. It keeps mineral particles in a suspended state for a long time, completely solving the problems of particle precipitation, stratification and dead zone in traditional flotation tanks. The uniform slurry concentration ensures consistent flotation effect of each ore particle and stable beneficiation indexes.
4. Adjustable Froth Scraper & Precise Grade Control
Equipped with adjustable-speed rotary froth scraper and flexible slurry level adjustment mechanism. Users can freely control froth thickness, scraping speed and pulp residence time according to ore properties and beneficiation requirements. It realizes precise switching of roughing, scavenging and concentrating processes, effectively improving finished concentrate grade and recovery rate to meet different ore processing standards.
5. Wear-Resistant Reinforced Tank Body & Long Service Life
The flotation tank body is welded with thickened steel plates and lined with high-strength wear-resistant anti-corrosion materials. It adapts to long-term impact and friction of high-concentration mineral slurry, effectively resisting acid-base corrosion and particle abrasion. Core transmission parts adopt sealed lubrication design, with low wear rate and long service life, reducing long-term replacement costs.
6. Modular Combined Installation & Easy Maintenance
Single-cell and multi-cell combined modular design supports free combination of roughing cell, concentrating cell and scavenging cell according to production scale. The overall structure is simple with few vulnerable parts. The open tank body design is convenient for daily cleaning, inspection and maintenance. The intelligent low-power motor reduces unit energy consumption, realizing energy-saving and efficient production.
Core Product Advantages of Flotation Machine
1. Self-Aspirating Design, Simplified Process & Low Cost
No need for external air blower and air supply pipeline system, saving auxiliary equipment investment and workshop space. The integrated aeration-stirring structure reduces production line failure rate, simplifies operation process, and greatly reduces daily operation and maintenance costs for mineral processing plants.
2. High Mineral Recovery Rate & Stable Grade
Uniform micro-bubble distribution and full slurry circulation ensure sufficient contact and adhesion between target minerals and bubbles. The recovery rate of valuable minerals is increased by 3-8% compared with ordinary flotation equipment. The adjustable froth scraping system ensures stable concentrate grade, avoiding large index fluctuations and improving overall mine beneficiation efficiency.
3. Wide Ore Adaptability & Flexible Process
It is suitable for flotation separation of gold, copper, zinc, lead, nickel, fluorite, talc and other non-ferrous metals and non-metallic ores. It can flexibly configure single-cell or multi-cell combined units, freely switch roughing, concentrating and scavenging processes, and adapt to small, medium and large-scale beneficiation production lines with diverse ore characteristics.
4. Anti-Precipitation & Full Suspension Flotation
The three-dimensional circulating stirring mode eliminates slurry dead zones and particle precipitation. All mineral particles are kept in uniform suspension state, ensuring that fine-grained valuable minerals will not sink and be wasted. It maximizes resource utilization rate and improves economic benefits of tailings recycling.
5. Energy-Saving & Low Consumption Operation
Optimized impeller power matching and fluid dynamics design reduce invalid power loss. Compared with traditional inflatable flotation machines, the comprehensive power consumption is reduced by 20-30%. The stable mechanical operation reduces frequent start-stop energy loss, realizing long-term low-cost continuous production.
6. Corrosion Resistant & Low Failure Rate
Wear-resistant and anti-corrosion lining materials adapt to harsh slurry flotation environments. The fully sealed transmission structure avoids slurry and dust erosion, ensuring stable operation of core parts. The equipment can run continuously for 24 hours with low failure rate and high production continuity.
Working Principle & Production Flow of Flotation Machine
Working Principle
The Flotation Machine adopts mineral surface hydrophobicity difference separation principle + self-aspirating bubble mineralization technology. The conditioned pulp mixed with flotation reagents is sent into the flotation cell. Driven by the motor, the impeller rotates at high speed to form negative pressure, automatically sucking air and fully mixing it with slurry.
The rotating impeller shears air into uniform micro-bubbles. Hydrophobic valuable mineral particles adhere to bubbles and rise to the liquid surface to form mineralized froth layer, which is scraped out by the scraper as high-grade concentrate. Hydrophilic gangue impurities sink to the tank bottom and are discharged as tailings. The circulating slurry system realizes continuous suspension, adhesion and separation, completing efficient mineral flotation beneficiation.
Standard Production Flow
Ore Grinding (Ball Mill) → Pulp Conditioning & Reagent Mixing → Feeding to Flotation Cell → Self-Aeration & Stirring → Mineral-Bubble Adhesion → Froth Concentrate Scraping → Tailings Discharge → Multi-Cell Combined Roughing/Concentrating/Scavenging → Finished Concentrate Collection
