Enhanced Methods For Nickel Recovery From Lowgrade Ores

A common method for nickel leaching from the matte is by using ammonia under high pressure, producing a nickel-bearing solution. This solution is heated to remove copper, and the use of hydrogen gas under high pressure precipitates nickel metal remaining nickel in the solution can be precipitated by adding hydrogen sulfide.
