This type of ore is common in the north of Brazil. The pure Au telluride is called "Brazilian Gold", by the way. About 40% gold content and it looks like gold. Many have been scammed. You roast it in air, and then you inquart it and part it with nitric. Very basic refining.giom said:to goldselverpro . iam100 percent sure .calvarite its one of the telluride gold ore you can do some search ..telluride gold .like sylvanite calvarite and about 5 more .its microscopic gold with silver .its caled electrum its not a normal gold ore its need a very high nowlege how to do the refining .and all start with roesting the ore to rid of tellurium .and need to be encaurted to under 6 karat its . need nowlge how to exactly do it i mean refinig this type of ore .the contant its . over 35 pecent of gold and you beter beleive it and iam not from nigiria .and iam willing to send a simple on my expence to some one very intersted and knew how to refine it .
Yes. You are right. The scam is when miners try to sell it as pure gold to the tourists or others that are not aware, when it really is only 35-40% gold.giom said:TO CUCHUGOLD .its dosnt looke like pyrite at all and the gold and silver its microscopic till you roest with air and converted to metal then it become all gray .its over 35 prcent no dought and no scam . iam very sure
