Collectors for Precious Metals Mining
Collectors are a critical component for precious metals mining recovery. Selectivity, collecting power and pH compatibility all impact your outcome. Collector performance is particularly important for gold and silver sulfides since they are difficult deposits from which to extract target minerals.
Nalco Water Collector Chemistry and Expertise
Effective collector chemistry is just the beginning. To reach optimal recovery, you need a partner who also has experience. Nalco Water offers both. Our collectors have a range of benefits, including high selectivity and stability over a wide pH range, that help you achieve your desired recovery.
Nalco Water Collectors for Gold and Silver
COLLECT-ORE™ C122 is a formulated collector offering unique benefits in the flotation of copper and copper-gold ores. In copper circuits, the unique formulation enhances copper selectivity and enables a high recovery. When used in precious metals containing ores, it is designed to boost gold recovery in Cu/Au circuits.
- High selectivity against pyrite.
- Selective towards copper in Cu-Pb-Zn flotation.
- Exhibits good activity over a wide pH range.
- Affinity towards precious metals.

These collectors exhibit an affinity for precious metals (Au, Ag, Pt), and they are typically used as a secondary collector in combination with a stronger xanthate. These products tend to offer enhanced selectivity against iron sulfides and particularly pyrite and are ideal when the recovery of copper minerals associated with precious metals is desired. They are effective collectors in the flotation of sulfide minerals and precious metals in the pH range highly acidic to moderately alkaline circuits, while offering enhanced selectivity against iron sulfides. They may offer improved flotation kinetics compared to similar collectors.
- Provide optimum recovery of both copper and precious metals.
- Excellent selectivity against iron sulfides.
- Lower dosage requirement compared to traditional sulfide collectors.
- Functional over a wide pH range.

These collectors are proprietary formulations suitable for precious metals collection in copper ores and platinum group mineral ores. They offer high recovery of sulfide minerals associated with precious metals. They also offer high stability across a wide pH range. The collectors are insoluble in water and are often added to the grinding mill or pre-conditioning tank.
- Improved copper recovery.
- Fast kinetics.
- Improved recovery of precious metals associated with sulfide minerals.
- Lower dosage requirement compared to traditional sulfide collectors.
