[D8952-F] (D-89-52) Mining

This folder contains correspondence and other documents relating to mining and ore milling in Canada, Chile, Europe, and New Zealand. Some of the items deal with inquiries about Edison's ore milling and processing machinery. Other documents pertain to ore samples sent to Edison from various sources. Among the correspondents are Osgood S. Wiley, an Edison agent in the United Kingdom who was dismissed in 1889; James Dredge, the coeditor of Engineering; and S. J. Ritchie, a businessman seeking to utilize Edison's ore milling process in Canada.

Approximately 60 percent of the documents have been selected. The following categories of documents have not been selected: routine correspondence regarding foreign mining properties and ore samples sent to Edison for assay; correspondence about Alfred O. Tate's Canadian business dealings with George D. Dickson and W. H. Dean; letters of transmittal; duplicate copies of selected documents.

##SECOND. How much iron will you be compelled to waste in the rocky matter which you separate from the iron? <1 1\/2 @ 2 units per oforiginal ore-->##THIRD. How high a grade of ore can can you produce from an ore carrying, as mine, say forty per cent. Of metallic iron? ##FOURTH. What would be the difference per ton in cost of producing an ore that would yield sixty per cent. And one yielding sixty-eight per cent? ##FIFTH. To how low a grade of ore can you use the whole product of the mine, without throwing any protion of it intot he waste heap, by sorting or separating it into second class piles? ##SIXTH. Allowing, as is usually the case in all magnet5ic ores, that thirty per cent. of the ore mined is thrown into the waste heap, these heaps usually carrying about forty per cent. of iron, how much of the cost per ton for mining can you save by grinding up the whole amount mined and saving all the ore contained in it? ##SEVENTH. Can you lower the phosporous contained in magnetic ores? ##EIGHTH. Will the fine ore which is obtained by your crushing and separating process be worth as much per unit of iron, when delivered at the furnaces, as the Lake Superior Bessemer ores containing an equally high percentage of iron? ##NINTH. Calling the mining of Canadian magnetic ores One Dollar per ton, the Railway and Lake freights One Dollar and sixty cents per ton, the duty Seventy-five cents per ton, seventy per cent. And thirty per cent. Carrying forty per cent. Can you deliver this ore in Cleveland at as low a price per unit of iron as the Lake Superior ores can be delivered at same place? The Lake Superior ores being subject to a royalty of Fifty cents per ton and the Canadian ores being free from royalty? <[No: overstruck] about the same-- can on above assumption of costs deliver a 68 percent ore Cleveland for $5 per ton, sure, against a 65 per cent from Lake Superior-->TENTH. On what terms will you erect, at your own expense, upon the line of the Central Ontario Railway at the mines belonging to the Anglo-American Iron Company in Canada, the plant for which you have now completed the plans, having a capacity for treating one thousand tons of ore per day? ##ELEVENTH. On what terms will you put up a similar plant having a capacity of two thousand tons per day? <67 cents>##TWELFTH. How soon can you have this plant in condition to work? ##THIRTEENTH. Do you think it practicable and advisable to put up a blast furnace for smelting this ore, and a steel plant for the manufacture of steel, in Canada? If so, what measures are necessary to be adopted by the Dominion Government? ##FOURTEENTH. Are you willing to become interested in the smelting and manufacturing of iron and steel, in Canada?
