[LB019324], Letter from Thomas Alva Edison to Alabama Mineral Land Co, Edmund Randolph, October 29th, 1884
Editor's Notes
Referring to yours of 20th inst my magnetic ore Separator will with a three horse power steam engine run through 75 tons of sand per day & separates pure with four per cent. If the Iron sand is passed through a second time it becomes pure within one per cent##The price of the Separator with Dynamo electric machine (but without engine or elevator to carry sand up to hopper) is $975.00
