Although Minnesota has a long history of iron ore mining, sulfide mining for copper, nickel, and precious metals has never been attempted. Prices for some metals, including copper, reached historic highs in 2011, and some companies have sought to mine Minnesota''s lowgrade sulfide ores.
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have ...
Nickel is commonly present in two principal ore types—sulfide or laterite. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt (Co), and often precious metals such as gold (Au) or platinum (Pt), palladium (Pd) and rhodium (Rh) (the platinum group metals or PGMs) (Naldrett, 2002, Hoatson et al., 2006).
