Title
[D8204ZCD], Letter from Thomas Alva Edison to Nathaniel Shepard Keith, May 29th, 1882
Editor's Notes
[attachment to D8204ZCD] The process of the electrolytic separation and desilverization of base bullion will effect the separation of the metals cheaply and effectually. 25 horse power applied to my dynamo will effect the desilverization of 12 tons of base bullion per day of 20 hours. The cost of 1 horse power per year 24 hours per day with coal at $4.50 per ton = $100.
