Which process did this plant test, don't they have a whole range of processes for different metals each requiring the types of feasability tests your referring to.

Would be good to hear some news of a successfull Zinc and nickel process.

Kiwi, You should go to their website to get a full understanding of the different projects they have. There are two main ones that people are getting confused about. There is the Hellyer Zinc Concentrate Project (50% JV with Polymetals) which is in operation producing Zinc concentrate from the old tailings damn, and will have Zn fed in from BSM and others into the future, and there is the Bernie Demonstration Plant, BDP, which has been tested but is now undergoing a feasability study to test it's commercial viability. This is being prepared by Ammtec and Worley Parsons and is due soon. This process can be applied to any metal and has been tested to produce zinc, lead, silver, copper and gold. You really should go back through their anns in detail to see the differences here. It's worth a read. Cheers.

I did read through some of the material. The process your talking about at the Burnie demonstration plant is a totally different process to the one been used at Hellyer.

From my understanding the Burnie demo Plant process is the one which will really make big bucks if it works. The metals that come from the burnie process will be almost pure zinc where as Hellyer is only concentrate.

I thought to extract each different type of metal also required a different chemical process, not one process that pumps out pure zinc, lead and nickel at the end.
 
The chemical processes used to process zinc at burnie are very similar to those used for copper and nickel.

I don't think there is any where near the potential value in the concentrate project as compared to the chemical leaching process.

Sure the Concentrate process can get more out of existing tailiings, blended ore and perhapes be used in EAFD but the leaching process is what will be used if anything comes of the JRV nickel deposit.
 
Hi Kiwikarlos, the demo plant process can actually extract more from the tailings than the concentrate process does!!! They will do a second pass on the tailings with the INtec process to extract what they miss when producing the concentrate.

Also the end product is PURE zinc, in tests it rated higher purity than Prime Western Grade zinc.

Finally I believe that the plant has separate circuits which simulateously extract ALL of the metals in the ore.... I'd need to double check this though, not sure how they manage it, but that is my belief... the copper and gold circuits did not perform to specification during the demo plants steady state period, but since they are going to be starting the Burnie demo plant back up in semi commercial mode, they might work on getting that right then.

RE: JRV & INL merger off

JRVs views on the INTEC (INL) process have been known since May 2006 at least.

Why force themselves on JRV? Pity people who bought JRV at 3c. They'll be happy the when the Chinese come over, grateful even.

http://www.jervoismining.com.au/uploaditems/reports/Dr Bryn Harris ALTA paper April 2006.pdf


Recently, Intec Limited described what also appears to be a somewhat complex new
chloride-based process wherein the limonite fraction of a laterite is leached by hydrochloric acid
in a solution of calcium and sodium chlorides [14]. The process can be operated in either one or
two stages, the first stage being at 100-110 °C and the second, or if it is just a single-stage
process, at 150-220 °C in an autoclave. In this process, both dissolved iron and magnesium are
precipitated via the use of lime, iron as hematite and magnesium as MgO. The process also
requires the substantial addition of sulphuric acid to regenerate the hydrochloric acid from the
resulting calcium chloride solution, with the sulphate balance being controlled by the further
addition of lime. The use of an autoclave and the large requirement for sulphuric acid seem to
mitigate against the use of this process, and unless a saleable form of calcium sulphate can be
produced [15,16,17], there will also be a considerable residue fall.
 
SP looks to be falling through (short term) resistance now. Next resistance at 15 cents; if that doesn't hold it could get real ugly
 
Couldn't be because they hold shares in a company that has no faith in them?: Wood himself practically admitting as to how "stupid" the JRV proposal almost was considering INLs technological "limits".

Wish they would just state what they intend to do with JRV. They seem to agree with JRV.

People now think they have 'invested' in JRV, hence the Patented Aspen process (competitors) for extracting Nickel.

Some even think they will come back for hostile takeover (?)

Makes no sense at all to me.
 
I don't know what their intention was, but all they achieved through the JRV merger proposal is put a real negative sentiment towards this stock.
Just can't believe how much the SP has gone down since January.
Now we are back to where we were 10 months ago.
I've been a faithful holder since May last year and have seen my profit shoot up to 120% in Dec-Jan and now it's down to 11%. Certainly not a happy camper here.
 

Hi Kennas
What does the BDP plant info say about Nickel? Do they anticipate it being feasable, chemically wise (Ni output, sulphur residue etc), viable, (cost effective)?

Ive ploughed through the INL website and the internet and still cant answer this one.
Thanks
 

Agree,

Took my medicine this morning and sold down 75%.
If 0.16c support fails the the rest is going as well, no point in holding two more months for CGT relief if theres no CG
 
Looks like the announcement has helped in slowing the haemorrhaging!
Lets hope it counters the negative sentiment somewhat.
 
Holding 8.3% of a 50mill company for a cost "less than zero"....that has to be a positive thing for INL. Given the (apparent) Chinese interest in JRV it is likely that this will be able to be utilised ie, converted to cold hard cash, or used as a handy bargaining chip in the short-medium.
No wonder the gnashing and wailing from the embittered JRV holders (see JRV thread). eg......"I can just see the INL guys now - geek nerd pimpled science types with bifocals and 7 gigabytes of pr0n, and NO socially redeeming features"
 
Ah Atomic.....Playing the person rather than the ball.....a typical response from someone out-played, under-equipped or out of their depth. Need I say more??? except to suggest that maybe labelling yourself "Atomic" is also a reinforcement of this. The stock forum equivalent of the under-endowed male tooling around in the phallic sports car....?
 
Let's keep it to INL guys, or the personal tit for tat goes. Thanks, kennas
 

ROTFLMAO!!!!!!
 

Sorry Atomic, but even you have to laugh at this, hehehe....

What a come back

Now, what's the topic again?
 
yeah especially as I wasnt born with a p**** ????

(last tat from me Kennas) .... and unlike Col I dont equate trading or JRV with "perfectly round luscious grapes" ???? and I already told him the hand is creepy.
 
Okay guys.... back on topic please.

From this point on any posts not related to INL will be removed and offenders severely spanked.
