The ore, coming from a district located one hundred and fifteen miles from the nearest railroad point, in a mountainous country, barren of coal, and where freight rates were enormous; demanded a method of treatment not now in general use upon this class of ores, and one that would require as little freight haulage either way, as possible. With these object in view, the following work was done, after reading all the data obtainable upon the subject as found in the school library --Introductory, page 1
