ore grades). Conversely, nickel production from laterite ores is relatively complex. Laterite mines are all open cut, due to the large area and shallow nature of the ores, and commonly apply a basic beneficiation to ore before processing (flotation is generally unsuitable). The next major step is high pressure acid leaching
