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.
