Introduction to Flotation Machine

Flotation Machine is a high-efficiency mechanical flotation equipment widely applied in ore beneficiation. It excels at separating non-ferrous metals (copper, lead, zinc, nickel), precious metals, and non-metallic minerals (coal, fluorite, talc) through roughing, cleaning, and reverse flotation operations. Driven by a motor, its impeller rotates to generate negative pressure, mixing ore slurry, air, and reagents thoroughly to form mineralized bubbles—useful minerals adhere to bubbles and are scraped out, achieving effective mineral separation. With reliable structure, stable performance, and broad material adaptability, it is a core device for mining and mineral processing plants seeking optimized separation efficiency.

Advantages to Flotation Machine

Multiple functions

It has three functions of air suction, slurry suction and flotation. Adjust the height of the ram to control the height of the liquid. The forward-inclined tank body has a small dead angle.

Good suspension effect

The double-sided blades of the backward-inclined impeller ensure reasonable slurry circulation, reduce coarse-grained sedimentation, and facilitate the suspension of coarse-grained minerals.

Durable components

The gap between the impeller and the cover plate is reasonable. When the impeller rotates, the internal pulp circulation increases the centrifugal force and increases the suction capacity.

Easy to operate

Ore slurry surface automatic control device, mechanical stirring, easy to adjust.

Working Principle to Flotation Machine

The Flotation Machine utilizes a mechanical agitation system combined with air-induction technology to achieve efficient mineral separation. Its core mechanism involves a rotor-stator assembly that generates turbulent flow and micro-bubbles within the flotation cell. Mineral particles are suspended in a slurry, and hydrophobic minerals attach to air bubbles due to surface chemistry differences. The rotating impeller creates negative pressure to draw air through a hollow shaft, forming a dense foam layer that carries attached minerals to the surface for collection. Adjustable parameters include agitator speed, airflow rate, and pulp density to optimize separation efficiency.
