If you do repost, and you would like to actually get the antimony from the rock (which is what it sounds like to me) then you will also have to tell us what rock it is...Or, I suppose...describe the rock so we can figure out which mineral it represents
.. because I was looking up how to get antimony out of Stibnite (the naturally occurring source of antimony, hence the symbol Sb), and it said that antimony is also found in Ullmanite (NiSbS) as well as others.
In any case, it is mentioned on one website, "It is not usually necessary to make antimony in the laboratory as it is commercially available." (WebElements, Antimony
) - but if you REALLY want to take it out of the rock, then try the midsection of this page: Click here
And, please, let us know what your question was actually concerning...whether this website answers your question or not...we can't go about ignoring other forum members.
