I am struggling to extract DNA from mine tailings even after enrichment due to suspected metal ions degrading DNA or inhibiting PCR reactions. I have used the following DNA extraction kits

  • Zymo Quick-DNA Fecal/Soil Microbe Kits
  • DNeasy PowerSoil Kit.

I heard about using chelators during the process of DNA extraction, anyone with such a method that worked? please share. Other methods that works are welcome too.

Thank you in advance
