    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.Aug 01, 2019 Ore grades are declining and costs of conventional underground mining are increasing. • In Mine Recovery (IMR) is an idea to recover the ore content in its ground position. • In IMR, underground stopes are converted to an underground leach reactor. • IMR has lower capital and operating costs, and subsequently a low cut off grade. •.
