Fine Gold Recovery and Gold Prospecting Equipment

I'm currently working on the development of technology which is ideally suited to the following applications:

  • Mining (gold, platinum, diamonds, gemstones and other minerals):
    • gold prospecting, exploration and bulk sampling
    • alluvial and placer gold mining operations where gold trommels, sluice boxes and panning are traditionally used
    • alluvial mining of other minerals including diamond and gemstone recovery
    • reprocessing of material from tailings dumps  
    • as a pre-concentration component in hard rock mines for fine gold recovery and mineral extraction - prior to, or in place of chemical processes  
    • for any mineral extraction or concentration application where gravity concentration is used, as an alternative to spiral concentrators
  • Sand and Gravel operations where gold and/or other minerals are present.
  • For environmental cleanups / lead remediation projects in decontamination of polluted land, specifically for lead shot or bullet recovery from trap & skeet, pistol and rifle shooting ranges
If you have a website and you can link it to www.extrac-tec.com, please let me know - I'd really appreciate it.
