I’m not sure how familiar everyone is with the Salt Roast Process, why we use it and what it does or indeed how it is affected by different inputs so I’ve put together a brief description for everyone.
Basically, as we get it out of the ground our Vanadium is in the rocks, but not evenly spread through the rocks, it concentrates in a crystalline matrix along with Iron and Titanium in a mineral formation that we call titaniferous-magnetite or just magnetite. When we get reports of the Magnetite content of our assets it is usually quoted as V2O5 in magnetite, so some may be wondering if it is already V2O5 why do we go to all the hassle of the salt roast process to make V2O5, isn’t there an easy way to just separate it out? The answer sadly is no there isn’t. The Vanadium is held in a complex crystalline matrix in which Iron, Titanium, Vanadium and substantially Oxygen atoms are rigidly packed together. Importantly there are a few others in there too notably Aluminium, Chromium, Calcium and Manganese in much lower abundance but the presence of these “impurities” is quite important later. Way back in the stone-age, cavemen probably first encountered “metal” as a strange shiny, malleable “rock” that they found at the bottom of their Fires. They had accidentally “smelted” metal from metal ores by having used the metal ore rocks in and around their fires as containment or for cooking (hot rocks packed with bound food and buried is an ancient cooking method). It was from these observations that the first metal production almost certainly emerged. So why can’t we just “Smelt” out our Vanadium. Well as it happens – we can and this is actually part of the process by which most Vanadium worldwide is produced, as a secondary product in the Iron and Steel Industry.
The typical titanomagnetite smelting operation entails (very simplistically) feeding the titanomagnetite with coal into a pre-reduction kiln. The prereduced material is then conveyed to a furnace where it is smelted to produce a vanadium-bearing pig iron metal and a by-product titania (TiO2)-rich ****. The vanadium-bearing pig iron is tapped into a shaking ladle where it undergoes oxidisation of vanadium into the **** phase. The iron metal from the ladle is tapped off for the production of steel. The remaining vanadium **** is then tipped out, cooled then crushed and the iron entrainment is removed by means of an overhead magnet leaving Vanadium (not very pure) behind. More typically that Vanadium **** (at anywhere between 20%- 33% Vanadium) is put through a salt roast process as we are about to discuss instead. It’s worth pointing out that Vanadium made through this classic “secondary” production process has a recovery of about 55-60%, so very wasteful compared with our Primary production method.
After Lincoln was shot and they cleared out his desk, they found dozens of letters written but never posted. As an example
a letter Lincoln wrote to a general who disobeyed his orders during the Civil War. Here's a snippet:
"I do not believe you appreciate the magnitude of the misfortune involved in Lee's escape. He was within your easy grasp, and to have closed upon him would, in connection with our other late successes, have ended the war. As it is, the war will be prolonged indefinitely. If you could not safely attack Lee last Monday, how can you possibly do so South of the river, when you can take with you very few more than two thirds of the force you then had in hand? It would be unreasonable to expect, and I do not expect you can now effect much. Your golden opportunity is gone, and I am distressed immeasureably because of it."
Clearly, this is a stern rebuke. You could even argue that it is personal.
Why didn't he send them ?...…….
Maybe Lincoln's thought process went something like this:
"Maybe I ought not to be so hasty. It is easy enough for me to sit here in the quiet of the White House and order Meade to attack; but if I had been up at Gettysburg, and if I had seen as much blood as Meade has seen during the last week, and if my ears had been pierced with the screams and shrieks of the wounded and dying, maybe I wouldn't be so anxious to attack either. If I had Meade's timid temperament, perhaps I would have done just what he had done. Anyhow, it is water under the bridge now. If I send this letter, it will relieve my feelings, but it will make Meade try to justify himself. It will make him condemn me. It will arouse hard feelings, impair all his further usefulness as a commander, and perhaps force him to resign from the army."
At work I used the same system with emails; write it to get it off your chest then don't send it. Posting on a Bulletin board is the 21st Century equivalent.
Just my thoughts
oh for goodness sakes grow up. Are you really the same poster who emailed me in March ? I can barely believe it. I've had enough interactions with him to recognise that he unlike some others is honest and honourable but I will leave him to speak for himself. I just don't like malicious nonsense be spouted by the uninformed. Demonstrably uninformed by the rest of their posting nonsense. You have changed @Coffeecups and not for the better. Sad.
@topsharepicks - a lot of what you are posting is verifiably wrong by anyone prepared to bother to look. For example at 14:40 you posted "Vametco produces around 2,600 tonnes of contained vanadium per year in the form of Nitrovan (vanadium nitride). It has reserves of 26 million tonnes grading 0.525% V2O5 in rock. "
From the BMN RNS of May 22nd this year
The aggregate Inferred and Indicated Mineral Resource is distributed across three Seams (The Lower, Intermediate and Upper Seams) and is reported as 186.7 Mt at an average grade of 1.98 per cent VO (in magnetite), with an average magnetite content of 35.0 per cent (in whole rock) for 719,300 tonnes of contained vanadium.
· Within this, the Ore Reserve in the Probable Category is reported as 48.4 Mt across the same three seams at an average grade of 2.02 per cent VO (in magnetite), with an average magnetite content of 28.5 per cent (in whole rock) for 156,300 tonnes of vanadium.
· The Lower Seam is the main ore seam and the thickest, ranging from 13.8 to 52.0 metres in thickness, comprising a Probable Reserve of 40.2 Mt at an average grade of 2.05 per cent VO (in magnetite), with an average magnetite content of 29.4 per cent (in whole rock) for 135,600 tonnes of vanadium.
So you are only out by a factor of about 7 times.
Just FYI - Alfacomp is a well known poster with a verified holding of over 11 million shares bought up to around 8p I believe so £2M profit given what a clever fellow he is is very likely. Please try and keep to facts not fraud and avoid defamation there's a good chap.
The only reason a few from the BMN board have looked in on here today is because of the nonsense being posted concerning BMN. Keep it to IRON and all will be good with no need to present actual facts and figures and you can keep the hurrah going all you like.
@BobbyAxe - assuming they are the same mass and purity then probably the one in Cape Town once you take necessary security and house and contents insurance into account. I mean - you know what Liverpool is like !!
@Coffecups - it has no place over here though so please again, keep it on the IRON board. You might like to make an effort to correct all the rubbish posted over there about BMN as well otherwise I may need to make return visits and you know how damaging the truth of an ugly fact can be. Start with the BS in the 14:40 post over there.
