How the rise of copper reveals clean energy's dark side
Chris Berry, an independent analyst focused on energy metals, said the push for clean energy is a big reason. The demand for copper is estimated to grow by 350 percent by 2050 if the world moves towards clean energy. Its price nearly doubled from 2019 to 2020 in the US. That's partly because copper's role in the transition to clean energy ...

Copper Mining and Processing: Everything you Need to Know
The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.
