[D8952ABR], Letter from George W Waters to Thomas Alva Edison, July 26th, 1889

Editor's Notes

"In reference to our conversation yesterday on the subject of working auriferous iron pyrites, I would like to ask a few questions, and beg your pardon in advance for troubling you on the subject again at present. ## In case the ore should show an increased percentage of copper, would it interfere with your process for the extraction of the gold? ## In the same case would your process ssave the copper also?"
