2017 - PRACTICAL ENTITLEMENT VANCOUVER, March 1, 2017 /CNW/ - Wellgreen Platinum Ltd. is pleased to report the results of its previously announced Phase 1 Metallurgical Testwork Program (the Phase 1 "Metallurgical Program"). The testing and mineralogy was performed by XPS Consulting & Testwork Services of Falconbridge, Ontario.
The objectives of the Phase 1 Metallurgical Program were (i) to refine and demonstrate recovery of payable metals following from work reported in the 2015 Preliminary Economic Assessment (2015 "PEA") see press release dated February 2, 2015; and (ii) to produce a marketable bulk Ni-Cu-PGM concentrate, including guidance regarding the possibility of producing separate Nickel and Copper concentrates.
The recently completed testwork has demonstrated that the geometallurgical domains are, and as such they will be referred to as: (i) Peridotite, which makes up the largest part of the resource, and (ii) Clinopyroxenite, which makes up a smaller part of the resource.
The Massive Sulphides and Gabbro constituting a smaller volume of material than the Clinopyroxenite may be tested during any subsequent metallurgical testing. The Company is very pleased to announce that the Phase 1 Metallurgical Program has succeeded in achieving all its objectives, including production of a quality,
marketable bulk Ni-Cu-PGM concentrate at 11.9% Ni-Cu grade for the Peridotite domain Produced copper recoveries for both Peridotite and Clinopyroxenite that exceeded the projections of the 2015 PEA (73% vs. 66%2, and 93% vs. 88%3, respectively). Produced nickel recoveries for Peridotite and Clinopyroxenite that are lower than those projected in the 2015 PEA (59% vs 68%4 and 71% vs 75%5, respectively). A suitable mini pilot plant exists within the XPS laboratory facility in Sudbury, Ontario."
Quantitative mineralogy has been used to estimate metallurgically recoverable nickel and copper ("Practical Entitlement").
Practical Entitlement recognizes that part of the feed metal units exist in a form that is either mineralogically unsuitable for recovery (e.g. nickel as low-concentration solid solution in magnetite or silicates) or in a form that is physically unsuitable for recovery (disseminated microcrystalline inclusions of metal sulphides within silicates). These values can be compared to the physically achieved recoveries in metallurgical testing, which reveal the magnitude of process losses associated with upgrading.

- solid solution ? remember the oregon gov paper -
50% nickel can be in solid solution silicates
- magnetite ? even metal flecks in silicates ?
last time i checked nickel iron = marketable concentrate
The Glencore - hazzardous report ( post earlier today )
States Glencore, does have
Hydrofluoric acid That they recover from certain ores
My hunch... fluorite.
But.... fluorite acid is the magic behind solubilizing = silicates.
Does
Sudbury region have serpentine / olivine nickel. Yes.... Does....Glencore recoups fluorine acids
Or just happens to have it ( readily avail ) for silicate nickel...
They recoup their sulphric acids...to reuse again.
Part of the nickel matte extraction process.
Would they do the same with, fluoric acid and silicates ?
By the sounds of NCP's 2017 Press Release,
I'd say they chose the wrong extraction company to perform tests.
Peridotite = Main ore
Related subject material claims nickel can be found in silicates as,
- pentlandite
- Ni sulphide
- Ni solid solution
- Ni bonds with other metals in silicates
Targeting the silicates
= liberates the metal, sulphur, solution = nickels.
This press might very well explain the turning point of,
avoiding specific nickel formulas
resulting in less percentage grade
less recoverables
Yup...I'd scrap their report
begin anew and confer with others who are nonbias with
silicate nickels that have nickel in solid solution.
My goodness, even magnetite and microcrystaline nickel.
Hmmmm...
Like i said...deal with the silicate = nickel drops out.
Convert to hydrofluoric nickel.
What would happen if NCP took 1 tonne Peridotite
Dunk it in Hydrofluoric Acid ?
Hydrofluoric acid can dissolve metals
(with the exception of nickel and its alloys: silver, gold, and platinum).May 27, 2021
And there you have it.
Years wasted.
Cheers....
