Kurt: A fire assay is where the sample is fired in an oven - this is in contrast to a wet chemistry assay. If it is not a "lead" fire assay, then instead of lead you can use Iron-copper-nickel, or Tin oxide, or Nickel sulphide, or Copper Sulphide (developed by Kallman and Blumberg of Ledoux - this does well for the platinum group metals)as a collector. If it is a "lead fire assay" then you can still use different fluxes and reducing agents and be within the parameters, and it is lead that is the collector. A "standard lead fire assay" is a lead fire assay with a little more restriction on the fluxes and the reducing agents. We are still in an extension period with Johnson/Lett. They continue to work on the process. Regards. Kim W.
