Atmospheric Pressure Leach process for Nickel ore LATERu00cdTICO

摘要

An atmospheric leaching process in the Recovery of nickel and Cobalt from laterite ores, the process includes the steps of: (a) to separate the Ore lateru00edtico in a fraction of a Mineral containing Magnesium,And a fraction of ore containing High Magnesium through Selective Post Mining or mining Classification; (b) separately from the slurry separated fractions of Mineral leaching; (c) The fraction of Mineral containing Magnesium with Concentrated sulfuric acid as a At the primary stage of leaching; and (d) introduce the mineral slurry containing High Magnesium to continBirth through twenty-one continu of substantial completion of the primary stage of leaching and precipitation of Iron as goethite or other form of iron oxide or hydroxide of Iron containing sulfate, sulfuric acid released during the precipitation of Iron, is used for the l The fraction of ixiviaciu00f3n ore with high Magnesium as a secondary leaching stage.
