Bob,
I suggest you read "Crucibles: The Story of Chemistry from Ancient Alchemy to Nuclear Fission" by Bernard Jaffe.
A fun read and very informative.

HI,
General question if anyone knows. What techniques did these chemists use back in the 1800's to isolate element?

Subject: [TN] NTC Friday Element Quiz The Question
Hi folks - here is the Friday Element Quiz:
The Question:
Only 5 metals have melting points higher than this element. It is nontoxic and is used in biomedical implants. It is a constituent in stainless steel, in nuclear fission reactor core structures, and is a substitute for the element Ta for aqueous corrosion resistance processing equipment. This element has nearly unlimited room temperature ductility characteristics. This element that had two different names up to the early 1950's until the international chemist union settled the discussion on which one was correct. Who am I?
The Answer:
The element is Niobium! As the old adage states " you can spot old American metallurgists from a thousand miles away, those troglodytic folks still say "columbium"! An English chemist, Charles Hachett identified an element he named "columbium" in 1801 and a German chemist, Heinrich Rose, identified an element he named "niobium" in 1846. It took a century of discussion before the element was officially named niobium in 1949!
Eric Christison was the first to correctly (and incorrectly after 1949) answer to the quiz. I'll be shipping my chair to him and sitting on several cases of Diet Coke until we get our 2011 budgets.
Everyone have a great weekend.
