Jasper County Democrat, Volume 19, Number 97, Rensselaer, Jasper County, 3 March 1917 — Rich Graphite Mines. [ARTICLE]

Rich Graphite Mines.

Important graphite- deposits near TurkuShansk are now being worked, and it is expected that the mines will supply sufficient mineral to fill the demands of the country and-leave a little for export purposes. Tests have shown that this mineral is to be had at this point in very large quantifies, but the most important feature of the mines is the purity of the yield, which Is said to average 98 per cent pure carbon. The graphite supply has heretofore corae mainly from Austria and Ceylon, but "the Russian mines promise to equal these sources of supply.
