Collectors for Zinc, Nickel and Copper Sulfides

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 collectors 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.
• Collectors 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.

Products Include: 

Nalflote C110, Nalflote C112, Nalflote C120, Nalflote C122

The NALFLOTE 300 series products have been successfully used for the flotation of molybdenite containing copper ores resulting in higher recoveries of molybdenite and improved subsequent copper molybdenite separations. They also have utility in the flotation of native copper and copper sulfides at low alkalinities, recovery of copper in smelter slag milling and as a primary collector in PGM flotation. This range of collectors also has proprietary blended 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 molybdenum and copper recovery in copper/molybdenum ores.
• Improved grade owing to high selectivity against pyrite.
• High performance over a wide pH range.
• High selectivity against pyrite.
• Affinity towards copper and molybdenite.
• Affinity towards precious metals in sulphide ores.
