Gold Extraction using borax

[Heatho]

Sorry to hijack the thread but can pyrite be melted to extract the gold content did I read that right? I'm interested if so I have a few good samples collected up from panning

You can, but the Sulphide (Sulphure Dioxide) gasses which come out while cooking are extremely noxious and can kill.

Hey GT Ive looked into it mate and its a bit of a process like Heatho said the process of roasting produces some yukky gas but it can be done, to put it in perspective thought on the cost v's reward basis I had this stuff tested and it came back as 1.4 gs/t which for a commmercial operation is probably ok but for jo blogs no way i aint chipping out 1 tonnne of rocks for a gram

Google Sulphide Gold mate

No stress guys Thanks for the info. I'll put it in the too hard basket. Just had a few samples where I'd like to extract the gold where is occurring with pyrite but it's more trouble than its worth.
