Mr. Wendell,
I cruise through the SI threads as a hobby, but in your your last post I see a few technical flaws.
You said:
>>Dissolve it in hot nitric acid, about 11%. Do this in a white porcelain-parting cup. After dissolution, study the bottom of the cup. Is there any blackish or blackish brown residue that would indicate gold? Study it well. That is why you used a porcelain-parting cup. It is the white background that helps to see the traces of residue metals. Go to the AA or ICP (Induced Coupled Plasma) for an analysis of the acid. Still no gold higher than maybe 2 parts per billion is reported, insignificant. The silver has truly met the acid test. My test.>>
With a portion of your statements I totally agree. For if you understand the priniciples of emission spectroscopy you would only detect the ionizing particles. Since Au can be carried in nitric acid as a colloidal, or sub-colloidal it would not be ionized within the chamber. Hence it would not be detected. Regarding blacks in a parting dish, please note that antimony produces blacks (it is not soluble in nitric acid) and is commonly associated with lead.
Furthermore, ICP is an acronym for Inductive Couple Plasma (not induced coupled plasma).
I am not being picky, but numerous references are made during the past 100 years regarding the fire assay of PGMs. The bottom line is it is difficult unless you inquart Ag or Au. Refer to pubilcations by Ammens, T. K. Rose and numerous others.
With total respect to Mr. Murray White (a man who I have communicated with for years and respect his +40 years in trying to unravel numerous mysteries) pay him his contractual fee and say take my ton of dirt and reprocess the slag and give me an ounce of gold. Is it contamination? Who knows? For you end up with three tons of slag from the ore.
Corporate research groups from ARASCO and Phelps Dodge have observed this mystery for the past 30 years. Guess what? They can do it in their laboratory, but fail when they enter into production. Those laboratories are now inactive.
Remember, it does not matter what assay technology that one finds that works on their mineral. What matters is -- will the mineral be acceptable to the end refinery!
The bottom line is -- if you have gold, put it in a pile, if you have platinum put in another pile. Now you have reality.
