Sulphides - Pentlandite metallics
Peridotite, Dunite - Clinopyroxine - all similar, silicate + crystalines + Mg + Fe
Gabbro - Think
black or green granite -
Quartz + Sulphide /
Quartz + Chloite If...silicates, solid solution, or crystalines are fine ground what happens ? = more exposed edges - liberates minerals ( metallic or dry particle in solid solution )
= acid can bond to mineral if silicate or crystal is fine ground.
Nickel Silicate ( Chlorite ) + Sulphuric Acid
Double Swap
NiCl2 + H2SO4 = NiSO4 + HCl There you go.
NiCl2 turns to
Nickel Sulphate If all ore types are finely ground and soaked in sulphuric acid
= minerals change to, sulphates.
Didn't xps pretreat the ores with a softening of sulphuric acid stage ?
Open circuit - what would that do ?
Convert some minerals to, sulphate ?
Hello....then place rest of ores in, closed circuit ?
July 10 2018
Process ore with a preconditioning of acid before closed circuit.
MPP:
The goal of the MPP was to build upon the technical success in Phase IIA employing the flowsheet improvements in order to produce a representative run-of-mine bulk concentrate sample of sufficient size to perform closed circuit (or locked cycle) testing of Cu/Ni separation.
MPP for Bulk Concentrate
The XPS MPP processed 1,100 kg of Run of Mine (ROM) ore with a head grade of 0.33% Ni, 0.15% Cu, 0.018% Co, 0.23 gpt Pt, 0.29 gpt Pd, and 0.04 gpt Au. The processing circuit incorporated conditioning with sulphuric acid @ pH 5.7 followed by rougher flotation and magnetic scavenging of the rougher tailings (Figure 1).
2017 needs to be revisted.
I'm thinking...aside of the presoak, with no mineral % acid capture reveal.
Our ores basically seen a sulphide ( metallic ) extraction.
Think - separate heavies.
Easiest extraction with flotation.
Question becomes
What would scrapping 2017 geology classification do
Introduce separate iron + pge's + heavy sulphides in metallic form
then... fine grind rest of ores with an acid soak
= convert silicate, solid solution, crystalines to = sulphates
= employ electrolysis ( this is how nickel metal is made )
= fetch premium price
As mention in prior posts....
Timmins juniors have dunite and peridotite
Anson has the olivines ( 90% solid solution with mega Mg )
= Each have no extraction issues
Here's another great example...
POWER NICKEL ( quebec )
Has the peridotites + sulphides
Thin widths nice grades
But thin widths = shaft mining ( can't grab it all )

Check out Power Nickel's ceo.ca bullboard. ( pnpn )
Interesting discussion on CEO will fight, naked shorting.

Also said, test Gabbs and Sulphides at later date.
Hard not to think, UG mine reserves.
Could this... test at later date not occurred, carried over to,
No measurement or extraction stats for eng firm ?
Can't report underground resources in reserves ...?
UG mine ?

Hard to say...
