Ball Mills - Mt Baker Mining and Metals Ball Mills Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation.
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 …

A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.
