Abstract

"The more or less impure iron bearing mineral occurs mixed with a very tenacious clay, in which are also found chert, cretaceous quartz pebbles, pockets of sand, masses of pebbles and sand cemented by hydrous iron oxide, (which in some cases partly replaces the silica) and several varieties of fossils, such as crinoids etc. The impurities mentioned are often an integral part of the ore particles, and are present in varying quantities thruout [sic] the deposit. But, besides the foreign matter which the eye can discern, the apparently pure mineral contains a varying percentage of silica and alumina, (as well as traces of other elements) which no mechanical process could possible eliminate"--The Ore, page 3-4.
