separation of nickel from a nickel ore

Enhanced methods for nickel recovery from low-grade ores and bleed streams

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.
