Challenges in processing nickel laterite ores by

2016-6-10  Until now, flotation process has not been successful to recover nickel from laterite ores. This has been associated with the complex mineralogy of the laterites. Therefore, the mineralogical analysis is essential to identify the type and amount of nickel-bearing minerals, as well as the degree of their liberation.

Nickel: smelting, producing-Metalpedia

In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe 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.
