Assayers in Australia

[Zacksgold]

Hi, How yall doing


I am looking for Assayers in Australia (preferably Brisbane). I want to send a sample of black sand from overseas (pacific islands near Aussie). I want to see how much gold content and possibly obtain a chemical recipe for smelting aka some metallurgic advice. Any Assayers you guys recommend that would be able to help with this?


Thanks

Look on-line for analytical labs in Australia, all of the international labs are well represented in all states.
The days of small independent labs are gone, really only the big boys are left.
A word of warning, all labs have a minimum spend and this is not a low number.
Commercial labs are not in the business of handing out trade secrets, most labs use just sulfide and oxide fluxes which are purchased premixed.
Nobody mixes their fluxes anymore, if you have a specific ore type then either they will use the standard commercially premixed fluxes or they will charge you a very large arm and leg for flux modification.
The art of custom fluxing has gone, lost in a sea of costings.
Email your lab of choice asking for a quote on both fire assay and 24 hour bottle roll.

All the more reason to learn the art and science of fire assaying. Having the skills oneself can mean the difference between losing money and success. The supplies are easy to come by and the methods are detailed in the old texts. And a lot of members here will pass on trade secrets.
