Blower in Mining Floating

In the mineral processing industry, flotation is a core technology for separating valuable minerals (such as copper, gold, lead, and zinc) from ore. This process relies on the interaction between mineral particles, reagents, and air bubbles—where air plays a decisive role in attaching to hydrophobic mineral particles and lifting them to the pulp surface for collection. Fans, as the primary equipment for providing stable and controllable air flow, are indispensable for ensuring the efficiency, stability, and cost-effectiveness of the flotation process.

The fundamental function of fans in mine flotation is to supply continuous, uniform, and adjustable compressed air to flotation cells. Unlike general industrial ventilation, the air provided by fans for flotation must meet strict requirements: appropriate pressure to penetrate the pulp (typically 30-100 kPa, depending on pulp depth and viscosity) and stable flow rate to generate sufficient small-diameter bubbles (0.1-1 mm) — the key to improving mineral recovery rate.

Without reliable fan support, flotation cells would fail to form a stable "bubble-particle aggregate" system: insufficient air leads to low recovery of valuable minerals, while uneven air flow causes pulp turbulence, reducing the selectivity of mineral separation and increasing reagent consumption.

The most direct application of blowers is aerating flotation cells (e.g., mechanical agitation flotation cells, column flotation cells). For mechanical cells, fans deliver air into the impeller area, where high-speed rotation shears the air into fine bubbles and mixes them with pulp. For column flotation cells—widely used in fine mineral separation—fans provide low-pressure, large-flow air to the bottom aeration device, generating uniform bubble layers that enhance the contact efficiency between bubbles and fine mineral particles.

In large-scale concentrators, multiple flotation cells are usually connected in series/parallel, and fans (often roots blowers or centrifugal fans) are configured with a centralized air supply system to ensure consistent air pressure/flow across all cells, avoiding differences in separation efficiency between individual cells.
