Energy and Environmental Profile of the U.S. Mining Industry 4

4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or open-pit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions. Small, low-capacity mines have rapidly disappeared.

Pennsylvania-Mines - Mining Artifacts

Workers used pickaxes and pry bars to get the ore out of the ground. After digging the ore, they tried to remove as much waste, including clay and soil, as possible from the ore. One method was to "flat" the ore, or roll cast-iron, horse-drawn breakers over the ore. In the nineteenth century workers also often washed the ore to separate waste.
