Butyl Diethanolamine Collector (BDEA Complex)
Butyl Diethanolamine (BDEA) collector complexes are nitrogen-containing chelating collectors used in the flotation of copper, nickel, and precious metal sulfide ores. The ethanolamine groups provide additional chelation affinity for heavy metal ions beyond the sulfide-binding group, enabling collection of both sulfide and partially oxidized mineral surfaces. BDEA complexes are particularly effective in circuits processing transitional (oxide-to-sulfide boundary) ore zones.
