The presence of the extra carbon makes it very hard, but it also makes it more brittle. High carbon steel is used for cutting tools and masonry nails (nails designed to be driven into concrete blocks or brickwork without bending). You have to be careful with high carbon steel because it tends to fracture rather than bend if you mistreat it.

Extraction of Resources Geology

Processing of ore from a lode mine, whether it is a surface or subsurface mine, requires that the rock ore be crushed and pulverized before extraction of the valuable minerals begins.

Bodie, California Hard Rock Mining

The ore is then cut out of the mountain by using large drills and black powder or dynamite, then hoisting those chunks of rock to the surface with ore carts and other bucket rigs. As the ore is removed from the mountain, the tunnels and shafts can become unstable and can cavein, so they must be shored up to keep the men safe and the tunnels open.

Ore Pretreatment or Beneficiation. A process step that may precede conventional agitation leaching and possible heap leaching is ore pretreatment, or "beneficiation," in order to reduce the quantity of ore that will require chemical treatment. Beneficiation involves separating some of the host rock from the uraniumbearing mineral.
