 · The techno-economic evaluation is performed on two different types of simulated copper ores. These two ores are referred to as Ore 1 and Ore 2 and are based on two types of actual copper ore which were investigated in our earlier work (Franks et al., 2013). The two ores are from the Ernest Henry Mine, Queensland, Australia (Xstrata) and from ...

Innovations: Introduction to Copper: Mining & Extraction

Copper Applications in Metallurgy of Copper & Copper Alloys. Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore.
