A typical steel plant uses over 2,000 megawatts of energy a year – enough to take up all the energy produced by a standard nuclear power plant. Toward cleaner mining. Mining and metals companies are working to lower their greenhouse gas emissions, but they are not on track to get to net-zero emissions.
Media Attributions; Metal deposits are mined in a variety of different ways depending on their depth, shape, size and grade. Relatively large deposits that are quite close to surface and somewhat regular in shape are mined using open-pit mine methods (Figure 8.1.5 in Section 8.1).Creating a giant hole in the ground is generally cheaper …
