Ore deposits | SpringerLink
In the Central African Copperbelt some 20 stratiform deposits comprise resources of over five billion tonnes of ore with grades of 2.5–4.5% Cu and 0.2% Co. Lead–zinc ore deposits are found in sedimentary basins in which comparatively low temperature (50–200°C), chloriderich, hydrothermal solutions (brines) leach and transport the metals ...Web
