    In hydrometallurgical processes nickel sulfide ores undergo flotation differential flotation if NiFe ratio is too low and then smelted. After producing the nickel matte further processing is done via the Sherritt-Gordon process. First copper is removed by adding hydrogen sulfide leaving a concentrate of only cobalt and nickel. Then solvent extraction is used to separate the cobalt and nickel with the final .

    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.

    Jan 01 2008 A basic principle of many processes for extracting copper and nickel from sulphide ores is to overlay the molten ore or matte with a lime–silica–iron oxide slag and blow with air or oxygen. Some of the iron present in the ore oxidises and as a result partitions to the slag phase while some of the sulphur is carried off as sulphur dioxide.

    This is done in a rotating converter of the type used in copper production. The slag is drawn off leaving a matte of 70 to 75 percent nickel. Because the conversion of nickel sulfide directly to metal would require an extremely high temperature in excess of 1600 C 2910 F the removal of sulfur at this stage of the converting process is controlled in order to produce the 70–75 percent nickel matte which has a lower .
