Nickel is classified as a transition metal.
Transition metals are elements between Groups 2 (metals) and 13 (non-metals) in the periodic table.
The periodic table is a chart that shows how chemical elements are related to one another. Nickel is closely related to iron, cobalt, copper, and zinc. Did you miss it ? Nickel is a transition metal.
What if the nickel is only in an ion form ? I would suggest - testing the cores for hte ion nickel before any ( acid or firing )
WHY ?
1 - hasn't decided to convert yet
2 - chemical influence may not be present for the conversion ( hint potassium )
3 - fire assay, or chemical acid test may sway an influence to deter a nickel dominate bond
4 - ions go up in smoke or chemically altered into another form ( guess )
TAKE FOR INSTANCE -
Silicon
Why or how is it... nickel can come in the form of, nickel silicate ?
Ahhhhhh......!
Suppose the nickel is in transition - just an ion -
some sort of reaction is needed to influence the nickel to form a bond.
Waht influence would be needed if the nickel was a sulphate in origin and decided to convert
to a - silicate nickel ?
Could a chloric acid or another salt do the job ?
How about - potassium - potassic influence ?
I knew there was something about the potassium - lol -
First words in ABSTRACT below - say it all.... wink.
Physico-chemical properties of potassium-promoted
Ni/SiO2 catalysts Abstract
K-promoted Ni/SiO2 catalysts have been prepared by adding KNO3 to the Ni/SiO2 precursor and subsequent hydrogen reduction. They were studied by XPS, infrared spectroscopy and magnetic methods. Chemisorbed hydrogen is strongly interacting with Ni surface atoms of K-promoted nickel catalysts, whereas oxygen penetrates deeply into the nickel particles with the formation of bulk NiO.
Evidence of an increase of the electron density of the metallic nickel due to the presence of potassium is given. CO is adsorbed on nickel in a bridge bonded form. K is mainly present in the K+ form and a Ni-O-K surface complex is probably formed. This complex is concentrated on the nickel surface into patches or islands. Ni interacting with the K-containing phase is accessible to hydrogen adsorption and not to CO adsorption. The hypothesis of Ni(111) arrangements of the free nickel atoms has been considered and no experimental evidence of a direct interaction between the promoter and the adsorbed CO was found.

When dealing with a transitional metal....
Whereas - the nickel might be in a - ion phase - not a metal - what should one do ?
Simple - FACILITATE it's transition.... introduce the formula in abstract above...
Hydrogen and potassium.
But first...
check to see if the ion of nickel is present - in the cores.. .without fire or chemical.
If the ion of nickel is present.. but hasn't yet - converted to as metal - is a good start -
The second half to this is...
How does the nickel bond to a silicate ?
Does it swap ions with a silicon metal ?
Can or could a silicon metal convert to a nickel due to nickel's dominance ?
Good questions...
Nickel is related to iron and colbat.
Yet.. if nickel is a treansitional metal... then, before becoming a nickel, what was it ?
Could one assign a simple - electron configuration ( xxx ion ) ???
Silicon is always present in numerous - rocks.
Quartz and felsic rocks are the breeding greounds for - al lthe - ites - biotites, pentlandites, aresonpyrites, chalcos - etc....
Can nickel exist without an iron presence ?
Many are now finding nickel amongst - magnesium deposits. ( Mg = salt )
Potassium appears to have a strong correlation to nickel transitioning -
Can we learn anything from - Sudbury ? What i likeabout this report is... they included the - silicon, magnesium, potassium - wink.
Beginning in 1971, all of the Inco drill core from Sudbury was analysed by the Inco Field Exploration Laboratory using a Philips 1270 simultaneous X-ray fusion (XRF) unit which was equipped with 14 channels (
Si, Fe,
Mg, Co, Ni, Al, S, Cu, Ca, Ti, Mo,
K, Zn, As). The XRF unit was calibrated using 200 samples which represented the various ore deposits in the Sudbury district. Samples were pressed in aluminum cups with a binder for 12 seconds at 15 tons on a Herzog press. Results for the pressed pellets for diamond drill samples were reported for copper, nickel, cobalt, iron, and sulphur. The XRF program also calculated a specific gravity based on intensities from the 14 channels. Three control samples at various sulphide concentrations were routinely run to ensure that the calibration remained accurate.
Starting in late 1990s, all core drill samples were prepared and analysed at the ALS Geochemistry laboratory using the
Na2O2 fusion/ICP procedure for base metals, iron and sulphur, whereas precious metals were analyzed by a fire assay/ICP method
All samples were analyzed for copper, nickel, cobalt, iron, sulphur, arsenic, lead and zinc using a sodium peroxide fusion with
inductively-coupled plasma (ICP) atomic emission spectroscopy (AES) finish (ALS method ME-ICP81).
When requested, lime,
magnesia and silica were also reported.

Now.. one could read into it a tad to much, but... when dealing with a transitional mineral,
i don't think one could analyse it enough.
If nickel can have two forms -
Sulphide and Silicate
Then.... how does the sulphide convert to the silicate nickel ?
Again... can a non metal nickel ion consume and take over a silicon metal ?
Does potassium facilitate this conversion ?
Should a junior test for - free nicekl ions - non metal form - in their cores ?
if present... could a lab assay -
plasma heat - complete the fusion of nickel ion to silicate ?
The Abstract paper is a big find for me....
It's like a missing link to what my hunch was pointing to... on own.
That there was something about potassium and a free roaming nickel...
I don't feel i have all the answers i need but am getting close to solving this...lol
I must also remind myself - chlorite also has an influence on potassium in felsics.
They do perform swaps... which then brings into play....
Serpentine, chlorite, nickel bonds.
The underlying takeaway in this post -
looking for nickel in metal and non metal - ION FORM.
Nickel is a transitional metal.
Some depoists - nature - already perform the conversion.
And the what if.... a junveile depoist was found - but the nickel hadn't yet converted ?
1 - What would the depoist look like ?
2 - What should one be looking for ?
= NICKEL IONS not yet converted. ( non metalic form )
= NICKEL in a partial transition - partially tied to say... silicate, with chlorite - solid solutiuon. .
Cheers....
