The best flotation result was for the S ore sample where nickel upgraded from 3.0% up to 4.2% (i.e. by 40%) at around 70% when HDMA was used. This is considerably better than nickel flotation grade and recovery data reported in the literature for this type of ores (i.e. saprolite) (Table 1). Based on these data, the best condition to upgrade ...
