Abstract

"Your letter of 4th instant to the Edison United M'f'g. Company, in regard to Mr. Edison's Ore Milling process, has been referred to us for reply. I enclose herewith a sketch and data pertaining to the ore milling machine, which indicates the horse power required for such machine in use. The cost of running the machine depends upon the cost of producing this power at the point where you desire to make separation. You will notice that a very slight charge will cover depreciation, as there are very few wearing parts to be considered. If your iron sands contain titanium [unclear] iron, we would furnish a special divider to separate the same from the concentrates and tailings. ### With reference to your question as to the percentage of oxide of [unclear], we could answer this more satisfactorily if we had a sample of 15 or 20 pounds of your iron sands to run through the separator which is working at this Laboratory. We could then send you sampled of concentrates and tailings for assay." Yours very truly, A.O. Tate [Marginalia: a labeled sketch of Ore Milling Machine----by Randolph?]
