Abstract
The pregnant solution obtained from high pressure and high temperature leaching of nickel-cobalt bearing low magnesium oxidic ores is neutralized at high temperature and pressure by coordinating the leaching of the low magnesium ores with the leaching of nickel-cobalt bearing high magnesium ores, the leach slurry from said low magnesium ore being neutralized by mixing it with said high magnesium ore which is simultaneously leached with said solution to produce a final pregnant solution from which metal values are subsequently recovered.
