Laboratory studies are performed for leaching oxidized nickel ore with hydrochloric acid in relation to temperature, leaching duration, and leaching acid consumption. It is revealed that the amount of hydrochloric acid dispensed has the greatest effect on metal extraction into solution. The maximum nickel extraction into solution is 88.2%.
