Application Strategies for Precious Metal Ore Flotation Defoamers: Core Tactics to Optimize Production

Scientific defoamer application is crucial for continuous and cost-effective precious metal flotation. Chemi Tech's systematic solutions cover the entire flotation process, enabling precise control.

Phased Application Strategies

Pre-flotation Treatment

Adding defoamers (0.05%-0.1% concentration) during pulp conditioning reduces stable foam from fine particles and residual reagents, ensuring uniform feed. Monitor pH and temperature for optimal dispersion.

Dynamic Control During Flotation

Automated dosing systems inject defoamers into different cell zones. For example, use low doses in roughing for suppression and higher doses in cleaning to prevent overflow. Adjust dosing based on real-time froth thickness (3-5cm).

Tailings Management

Spray systems with Chemi Tech defoamers eliminate surface foam in tailings ponds, minimizing metal loss and pump cavitation.

Key Parameters

Dosage:5-15g/t ore, adjusted by ore type (sulfide/oxide).

Dilution: ≤1:10 with hard water; avoid prolonged settling.

Mixing: High-speed agitation (≥1200rpm) ensures uniform dispersion.

Chemi Tech offers customized solutions through lab simulations and on-site trials, enhancing process stability and equipment longevity.
