MAXGOLD® chemistry has been shown to offer the following improved performance characteristics in the flotation plants:
Demonstrated robustness in plant operation – reduced variability in plant recoveries, and improved overall gold recovery of 2-4% or greater.
A greener profile than standard products, especially xanthates.
Very effective in the flotation of pyrite and arsenopyrite in mildly acidic and neutral circuits.
Can operate in a broad pH range, thus it can be used for copper/gold ores with selectivity against pyrite in mildly alkaline and alkaline pulps.
Provides greater flexibility in terms of addition point (mill, sumps, conditioners, regrind, etc).
Can also be also used as a secondary collector at low dosages (5g/t-15g/t), in conjunction with other collectors in the rougher or cleaner circuits.
Faster kinetics in the flotation of sulfides and precious metals than traditional collectors; this is an important advantage in circuits with shorter residence time.
Improved recovery of middlings or composite particles.
Effectiveness at significantly lower dose rates as compared to traditionally used collectors such as xanthates.
Greater flexibility in use as a partial replacement for xanthates.
Excellent collector for bulk sulfide flotation and precious metal values including free gold, electrum, and tellurides.
Excellent collector for Cu, Au and Mo values from Cu-Mo-Au ores requiring no secondary collectors.
Can be used at low doses (5g/t-10g/t) in flash float cells, improving recovery of precious metals and gold-bearing iron sulfides.
