Copper beneficiation collector (4 replies and 2 comments)

Now we are having problems in the selection of the flotation collector for a copper ore, in lab test we can´t see any difference in concentrates with sodium amyl xanthate and sodium isopropyl xanthate. Based on your experience which promoter supposed to work better in copper beneficiation?

Hola Omurvama,

What are your sample's assays?  Ore geology deposit type? Can you post your flotation tests results? What were your %mass pull? Frother? Etc etc.

If you can not see a difference, it could be that you are overdosed on both to begin with.

If you can reply with a PDF of your test results, that would be great.  

KAX is a classic for copper only ores.

What I found at Vatukoula Gold Mines, I could get a better recovery using a blend of PAX and SIBX rather than using either of the collectors at even higher dosages. I suspect this is due to the different length xanthate chain reacting differently with different sulphides. As with all process plants, differences abound

Collectors in reverse order of strength (strongest to weakest):

  1. PAX
  2. SIBX
  3. SIPX
  4. SEX
  5. Methyl Xanthate (uncommon)
What is the strongest xanthate
So yes, initial dosage is important.

Try to carry out optimization tests using various combination ratios of these collectors.

Currently we are using MX 5149 as a primary collector and SEX secondary. David, MX is stronger than SEX but less selective.
