Ball Mill | A ball mill at the old White Pine mine. This was

A ball mill at the old White Pine mine. This was one of many attempts to make mining the Nonesuch Shale pay -- a bed of sandstone with extremely fine copper embedded in it. The Nonesuch mine (in the Porcupine Mountains) was the first attempt, with the old White Pine coming again later. It took quite a long time -- until the 1950's! -- for the Copper Range Company to solve the problem (at which
