Processing of lateritic nickel ore

The first commercial operation to utilize sulfuric acid pressure leaching to process nickeliferous laterite ore was Freeport Sulfur’s Moa Bay plant in Cuba The Cuban government expropriated this plant in 1960 shortly after startup The ore contained about 48 Fe 5 Al 4 SiO2 14 Ni and less than 1 Mg
