Why almost every element would be metallized in sufficiently high pressure and low temperature?

(This statement is from wikipedia, BTW). What is so special about metallic bond that is limiting high-P low-T state of a matter (as long as individual atoms exist, not white dwarf of neutron star...

Lyophilize. The ammonium formate should evaporate as ammonia and formic acid.

You may have to repeat this a number of times. Form a shell in the flask using dry ice/isopropanol. If you get a gum that still stinks of ammonium formate, add deionized water, freeze a shell, and lyophilize until you obtain an odorless powder.

Thanks Matthew... As the extraction trials were not working i went for Lyophillization only but i got traces of ammonium formate. As you suggested to repeat it.... i will do that.

Pass the solution through Ion exchange resin if Impurity is not highly polar.
