Iron ore and its containing rock are blasted loose with high-explosives, making the ore accessible to machinery and small enough to be transported to the plant. Hauled by monster dump trucks capable of carrying over 300 tonnes of earth at a time, the ore is transported to a ROM Bin, where it begins its processing phase.

Ancient debris is one of the most valuable resources in Minecraft, due to it being a source of netherite scraps and thus netherite ingots. It is found in the Nether most commonly at Y=15, although mining at lower levels is safer due to lower risk of mining into a lava ocean. While strip mining is still a potential and straightforward way of mining for ancient debris, …

The First Open Pit Mining Site – The Jackson Mine. Discovering iron ore was easier than mining it. This first open pit mine in the Lake Superior region started as a mountain of ore 150 feet high. Workers began prying ore from the surface with a bar and pick. Later they hand- drilled holes and filled them with explosives to fracture the ore body.
