Ore Processing

Flotation Machine

A flotation machine is an essential industrial device used to separate valuable minerals from ore by leveraging differences in their surface hydrophobicity.  It employs aeration and agitation to create bubbles that selectively attach to target mineral particles, floating them to the surface for collection.  Widely utilized in mining, metallurgy, and wastewater treatment, this equipment ensures efficient mineral recovery, high processing capacity, and adaptability to various ore types, including copper, gold, lead-zinc, and coal.

Description

Flotation machine is the abbreviation of flotation concentrator, which refers to the mechanical equipment that completes the flotation process. In the flotation machine, the pulp treated with reagents is stirred and aerated, so that some mineral particles are selectively fixed on the bubbles; the particles float to the surface of the pulp and are scraped off to form foam products, while the rest remain in the pulp to achieve the purpose of separating minerals.

Working Principle

Flotation Machine
1. Agitation & Aeration: A motor-driven impeller agitates the slurry while introducing air to generate bubbles. 2. Bubble-Mineral Attachment: Hydrophobic mineral particles attach to air bubbles, forming a froth layer. 3. Froth Collection: The mineral-laden froth overflows or is skimmed off the surface. 4. Tailings Discharge: Unwanted materials (gangue) sink and are discharged from the bottom. 5. Adjustable Parameters: Airflow, impeller speed, and reagent dosage are optimized for separation efficiency.
