Silica Collectors

In the mining of ores and their beneficiation, there are often minerals and their associated gangue that do not possess sufficient hydrophobicity or hydrophilicity to result in an apt separation even after proper froth flotation. Thus, various other additives are often used in froth flotation to enhance the properties of appropriate minerals to get an economically feasible separation. Collectors are an example of additives that improve the hydrophobicity and hence the floatability of different minerals. Effective collectors must be able to:

1. Selectively attach or "glue" to the target molecule or molecules almost exclusively to other molecules that are present; 
2. Hold the attachment well even with the high shear and stress related to flotation; and,
3. Furnish the target species or molecules amply hydrophobic to allow an acceptable level of separation.

For ores that contain silica, it is often economically beneficial to remove the silica early on in the process. With NAQ Global's latest silica collectors, it is possible to get the following benefits:

  • High Recovery of Silica
  • Drastic Reduction In Silica Carryover
  • High Selectivity

Another advantage of our silica collectors is that they are available in three different forms: solid flakes, concentrated paste, and ready-to-apply liquid.
