On the other hand ore concentrates traded internationally require 65-75% WO 3. Therefore a very high amount of gangue material must be separated. This is why ore dressing plants are always located in close proximity to the mine to save transportation costs. The ore is first crushed and milled to liberate the tungsten mineral crystals.

Berkeley Pit - Wikipedia
The open-pit style of mining superseded underground operations because it was far more economical and much less dangerous than underground mining. Within the first year of operation the pit extracted 17000 tons of ore per day at a grade of 0.75% copper. Ultimately about 1000000000 tons of material were mined from the Berkeley Pit.
An important precondition for LKAB's cost-effectiveness is our material magnetite ore as well as the energy-efficient pelletizing process. The processing of the iron ore commences once the ore has been transported to the sorting plant from the underground and surface mines.
