Abstract

"Referring to your favor of the 9th instant, there must be something wrong in the analysis you sent me, as the total doesn't foot up 100%. The original ore had about 20% iron in it. We simply raised the concentrate to 41.5 by tumbling. It probably could be got up to 45%, which is equivalent to a 55% magnetic ore." Yours truly, [signed] TAE
