Title
[D8034ZCV], Letter from John Heinz to Thomas Alva Edison, June 17th, 1880
Editor's Notes
Read in Sydney paper about TAE process for working quartz tailings; lots of quartz here. Marg: You read the paper wrong; "we are however at work experimenting on mill or quartz tailings as these are very rich in most of our mines & we have just perfected a method of working low grade sulphats (iron sulphurite) containing only but little arsenical sulphides we will correspond further [illeg]."
