Cool.
Did you look on the wiki to see if there are any others? I know for example that thorium has been done.

I am in the process of digesting some tool steel in HCl to extract vanadium. It will eventually be a video - and quite different from Tdep's efforts. His was recovery of the products of a thermite that was done on a beach. Separation of sand and oxide is quite different from separating Fe and V in solution.

I have an article describing two methods for Cobalt metal starting with CoCl2 if someone's interested.
http://pieceofscience.com/cobalt-metal-preparation/
I thought about trying ZrCl4+Mg to get the zirconium but not sure how well would it work, have anyone done it before?

Acually i got half way there is alot of info
Going to add more later with an edit
Just wanted to let the idea flow

I wanted to add the ones who have isolated
And in the refrence of my post i was going to add links to the findings in a post and youtube videos of isolations with the username

A compitition of who can isolate the most elements.

Hydrogen - Iron and sulphuric acid
Lithium (if it counts) - batteries
Boron - from borax via boric acid and documented in many places https://www.youtube.com/watch?v=FAxqKQQ0wZU
Carbon - from thermal decomposition of sucrose
Oxygen - from thermal decomposition of potassium permanganate
Sodium - NaOH/Mg
Silicon - sand/Mg
Sulphur - sodium thiosulphate and hydrochloric acid, but not sure if this is worth documenting given its availability :P
Chlorine - potassium permanganate and hydrochloric acid
Vanadium - from vanadinite mineral (far from perfect process - digest with HNO<sub>3</sub>, ppt Pb with NaCl, basify until V<sub>2</sub>O<sub>5</sub> precipitated out, redissolved and reduced with zinc, ppt V(OH)<sub>3</sub>, thermally decomposed, then thermite
Chromium - chromic oxide/Mg
Manganese - Mn<sub>2</sub>O<sub>3</sub>/Mg https://www.youtube.com/watch?v=3f6VE1USBDQ
Iron - Rust/Al
Cobalt - CoCl<sub>2</sub> displacement with Zn
Copper - displacement from copper sulphate solution :P https://www.youtube.com/watch?v=li0HmTZZuzw
Gallium - electrolysis of sodium gallate
Bromine - KBr/MnO<sub>2</sub>/sulphuric acid
Antimony - stibnite reduction with aluminium
Mercury - from cinnabar via Plante1996's process, documented by NileRed https://www.youtube.com/watch?v=0e78I9_oH1E&t=601s

Acually that was exactly i had in mand a lot more organized and detailed too
Yes extraction from batteries count
Just not strait out buying it pure

Edit removed my long signature

I made cobalt with thermite before.
Crude and low quality manganese can also be made with MnO2 Thermite with excess Aluminium.

VSEPR_VOID - 19-5-2018 at 11:25

Make sure to add what you make to the SM list

I'm more into collecting compounds than elements, so my list is pretty meager, but it includes bromine, hydrogen, oxygen, zinc, carbon, chlorine, copper, and sulfur... probably a few more....


MrHomeScientist - 21-5-2018 at 06:23

I've done quite a few via Goldschmidt (thermite) reactions: B, Si, Ti, V, Cr, Mn, Fe, Sn

Elements isolated from other reactions: H, C, N, O, Cl, K, Cu, Br, Ag, I, Nd (maybe)

Plus a few more "isolated" from OTC sources, like Li from batteries, but I don't think that really counts.

Each has its own story, but would take quite a lot of time and space to write out!

I isolated the following elements:

Br2 : NaBr + NaHSO4, using electrolysis
Cl2 : TCCA + HCl, Ca(OCl)2 + HCl, bleach + HCl
I2 : KI + dil. HCl + dil. H2O2
Se : Na2SeO3 + dil. HCl + SO2 (or sulfite)
P4: heating of red P
As : Reduction of As2O5 in conc. HCl, using SnCl2 (bad yield, just 10% or so, dared not use stronger reductant, because of fear of formation of AsH3)
C : heating of wood, sugar, starch
H2 : Zn + HCl, Mg + HCl
K : Mg + KOH + t-butanol in alkane solvent and heating
Ag : From AgNO3 and hydroquinone in solution, gives very fine powder
Cu : From CuSO4 and sodium dithionite in solution, gives very fine powder
S : From Na2S2O3 and dil. HCl

Of most elements, mentioned above, the making and isolation of them in a reasonable state of purity only is interesting for the sake of experimenting and practicing certain types of chemistry. For me, the only elements worth isolating for having access to the element itself are Br2, Cl2, K, P4 and As. The other elements I bought. This was easier and also cheaper than making them myself and gives me much better purity. The most succesful one for me is bromine. I made a fairly large amount of that at high purity and perfectly dry and made a few nice samples of that. My powdered As-sample is nice, but small, it only is 200 mg or so.

Here is the elements isolated by the comunity 32 elements

symboom - 22-5-2018 at 20:39

32 elements isolated
Out of 92 elements
We are 1/3 the way there
Someone double check this

Excluding the very hazardous
21 total
Helium
Argon
Neon
Krypton
Xenon

Fluorine
Francium
Radium
Cadmium
Barium
Promethium
Thallium
Polonium
Astatine
Francium
Actinium
Protactinium
Fluorine
Technetium
Beryllium

39 elements left to isolate

Also started this thread so aga wont keep saying no one does any real chemistry on here and prove him wrong :/

So any ideas about a Hazard count by elements isolated
Using the least amount of reagents
