The cost of sorting 1 ton of $68.64 ore from the run-of-mine product is $1.95. Expressed in another way, the sorting cost per ton of run-of-mine ore is 1.95/6.51 or $0.30. The cost of mining 1 ton of run-of-mine ore is $2.34. The cost of transporting …

Furthermore, it is not uncommon for underground miners to be U paid more per hour than a worker doing a similar job on the surface. For these reasons, in conjunction with the better productivity and time utilization of surface operations, the labor cost per effective working hour in underground mines is much higher than on the surface.
