A new generation of flotation chemistry

Flotation chemistry, engineered for selectivity.

As copper ores become more complex, conventional flotation collectors face increasing limitations. Giraffe Bio develops bio-collectors tailored to each operation, enabling greater control over mineral selectivity and hydrophobicity.

Mineral-Specific

Designed around the interaction that matters.

Every orebody is different. We start with the mineral surface, ore characteristics and the metallurgical objective to engineer the best collector.

Drop-in

New chemistry. Existing infrastructure.

Designed to integrate into existing flotation circuits and dosing infrastructure, without requiring new equipment or a flowsheet redesign.

Material Impact

Demonstrated recovery uplift +3–5 percentage points

Performance varies by mineralogy and operating conditions. Our collectors are validated on real ores and measured directly against baseline chemistry.

Observed in lab-scale validation using real mine samples under representative flotation conditions.

Mineralogy sampling

  1. (001)Design

    Engineer the interaction.

    We design biomolecules to selectively interact with the target mineral surface.

  2. (002)Formulate

    Build the collector.

    We incorporate the most promising biomolecules into formulations engineered for flotation performance.

  3. (003)Validate

    Test against baseline.

    We test our collectors on real ores, under representative flotation conditions and directly against baseline chemistry.

Frequently
asked questions

  • No. Giraffe Bio collectors are designed to work within existing flotation circuits and dosing infrastructure.

  • No. The final product is a cell-free flotation reagent. It contains no living organisms and requires no biological process for the plant to operate.

  • No. The technology is designed as a drop-in solution for existing flotation circuits.

  • Conventional collectors primarily rely on chemistry that combines mineral affinity and hydrophobicity. Giraffe Bio's bio-collector architecture enables mineral selectivity and flotation behavior to be engineered more independently, allowing the reagent to be optimized around a specific mineralogy and metallurgical objective.

  • Performance depends on the orebody, mineralogy and operating conditions. Giraffe Bio evaluates representative ore and validates candidate collectors under relevant flotation conditions.

  • No. Performance varies by mineralogy and operating conditions. The recovery improvements highlighted on this site reflect results observed in recent validation programs and should not be interpreted as a universal performance claim.
