Flotation Machine

1.Product Introduction

The flotation machine is a key piece of equipment in mineral processing, used to separate and concentrate target minerals through the flotation process. Its core function involves introducing air into the pulp to generate bubbles. By exploiting differences in the physicochemical properties of mineral surfaces, useful minerals selectively adhere to the bubbles and float to the pulp surface, forming a froth layer that separates them from gangue. Modern flotation machines have evolved into various types, such as mechanically stirred, air-injected, and combined models, to accommodate different mineral characteristics and processing plant scales.

2.Application

• Flotation machines are widely used in the separation of non-ferrous metals, ferrous metals, and non-metallic minerals. Specific minerals processed include copper, lead, zinc, nickel, molybdenum, gold, iron, sulfur, bauxite, apatite, potash, cobalt, and spodumene. The process stages encompass roughing, scavenging, and reverse flotation.
• Additionally, specialized models address specific requirements. For instance, the YX flash flotation machine primarily recovers precious metals from grinding and classification circuits, preventing over-grinding while enhancing recovery rates. The HIF series of ultra-large intelligent flotation machines, meanwhile, meets the demands of large-scale mineral processing plants handling over 100,000 tons per day.

3.Working Principle

The fundamental operating principle of a flotation machine involves generating numerous bubbles within the pulp through mechanical agitation or external aeration. Target mineral particles selectively adhere to these bubbles due to their surface properties, rising to the pulp surface with the bubbles to form a mineral-rich froth layer. This layer is then skimmed off as concentrate. Unattached gangue particles remain in the pulp and are discharged as tailings, thereby achieving separation.

4.Advantages

• High-efficiency separation and broad applicability: Effectively processes various metallic and non-metallic minerals with excellent flotation performance. Next-generation equipment like the HIF series employs an innovative kinetic partitioning architecture to simultaneously recover refractory coarse and fine-grained minerals with high efficiency.
• Robust and Flexible Processing Capacity: Equipment specifications span a wide range, with unit volumes from 0.2 cubic meters to super-large 800 cubic meters, meeting diverse needs from small-to-medium to super-large mineral processing plants.
• Low Energy Consumption and Stable Operation: Advanced impeller-stator designs (e.g., backward-curved blades, open-blade stator) enable high flow rates and low head pressure, reducing power consumption. ‌Power intensity for certain models can be as low as 0.55 kW/m³, achieving over 20% savings in aeration power consumption.‌Equipment maintains reliable operation with 24-hour full-load start capability.‌
• ‌Convenient Operation and Maintenance‌: Simple foundation design minimizes footprint.‌Flexible configuration options (stair-step or horizontal) facilitate installation, operation, and maintenance.‌
• High Intelligence and Automation: The new-generation intelligent flotation machine integrates automatic level and air volume measurement/control, optimized foam velocity control, equipment fault diagnosis and early warning, real-time online monitoring of multiple parameters (e.g., bubble characteristics, concentration, pH), and cloud platform remote data services. This significantly enhances the intelligence and stability of the production process.
• Optimized structural design:‌ A rational pulp circulation design minimizes coarse sedimentation;‌ unique feed and discharge structures (e.g., in flash flotation machines) improve internal concentration control.‌
