Collectors for Zinc, Nickel and Copper Sulfides
Collectors are a critical component for zinc, nickel and copper sulfides flotation. Selectivity, collecting power and pH compatibility all impact your outcome. You also need a partner with the right chemistry and proven experience-and Nalco Water has both. We have a proven track record in mineral processing, and our collectors have a range of benefits, including high selectivity and stability over a wide pH range, that help you achieve your desired recovery.
Flotation 360™
Mineral processing optimization can feel like a moving target. Changing ore, an incorrect formulation or failing to balance recovery and grade can impact your bottom line. But Nalco Water has your solution: Flotation 360. This digital technology helps you maximize productivity and optimize your flotation circuit performance.

Nalco Water Collectors for Copper, Zinc and Nickel
The NALFLOTE 100 series is a collector range used in the flotation of sulfide minerals at alkaline pH, particularly those associated with copper, molybdenum, gold and silver. These frothers exhibit improved selectivity against pyrite compared to commonly used xanthate collectors. These collectors are often used in combination with a secondary thiol collector in order to improve secondary metal recovery such as those associated with gold and silver. They are suitable xanthate replacements.
- High selectivity against pyrite.
- Collector for primary and secondary copper mineralogies, especially where molybdenum is recovered.
- Exhibits good activity over a wide pH range.
- Affinity for copper in Cu-Pb-Zn flotation.

These collectors are used to float copper sulfide minerals and precious metals in acidic to slightly alkaline circuits. They are often used as a secondary collector in Cu-Au flotation with the primary collector being a xanthate. With precious metals, they are effective at improving recovery and selectivity in acid and neutral pH circuits. With copper ores, they are designed to improve selectivity in alkaline circuits.
- Increase molybdenum grade through improved selectivity.
- Improve selectivity against pyrites and sulfide gangue minerals.
- Improved precious metal recovery.
- Lower dosage requirement compared to traditional sulfide collectors.

The NALFLOTE 300 series is a specially formulated collector range particularly suited for molybdenum flotation with a primary xanthate or thiocarbamate. They offer high stability across a wide pH range. The collectors are insoluble in water and are often added to the grinding mill. They offer improved selectivity against pyrite compared to traditional xanthate collectors.
- Improve molybdenum and copper recovery in copper/molybdenum ores.
- Improved grade owing to high selectivity against pyrite.
- High performance over a wide pH range.

The NALFLOTE 400 series is a proprietary blend of thio esters designed for Cu, Cu-Mo and Cu-Au ores. The collectors are insoluble in water but are often added directly to the flotation cell because they have a fast reaction time. The collectors are extremely selective against pyrite compared to standard collectors such as xanthates.
- Improve copper recovery.
- Improve selectivity against pyrites and mineral sulfides.
- Improve precious metal recovery.
- Lower dosage requirement compared to traditional sulfide collectors.
- Xanthate replacement.
