Chemi Tech Defoamer Solves High-Slime Flotation Foam

Foam stability exceeding 50cm in hydrometallurgical flotation with >15% slime content causes valuable metal loss. Chemi Tech's KM-880 defoamer overcomes this through charge-directed adsorption technology.

Mechanism: Dual-Mode Foam Collapse

Ionic targeting: Positively charged modified polysiloxane adsorbs onto negatively charged slime particles (e.g., silica, hematite), disrupting foam stability;

Rheology control: Reduces slurry viscosity by 28%, accelerating bubble coalescence.

Case: Copper Recovery Optimization

At Brazil Copper Mine, 22% slime content caused 50cm foam layers and 81% Cu recovery. After KM-880 application:

Precision control: 0.3‰ dosage reduced foam to 15cm thickness within 40 seconds;

Efficiency gain: Copper concentrate grade reached 25.3% with 90.7% recovery, generating $4M+ annual value;

Compatibility: Zero interference with xanthate/dithiophosphate collectors.

Multi-Mineral Adaptability

Zinc leaching residue: Maintained >92% indium volatility at 1250°C;

Complex ores: <0.8% cross-contamination in Cu-Pb-Zn separation.

Chemi Tech's molecular weight fractionation enables KM-880 stability across pH 2-12, ideal for silver flotation from acid leach residues.
