Our analysis shows that natural density of the two kinds Emeishan basalt saprolites ranged from 1.46 to 1.65 g/cm 3, much less than that of the fresh Emeishan basalts.The average hydraulic conductivity of the two types of Emeishan basalts is 10 2 –10 3 times of those of the fresh Emeishan basalts. These differences indicate that the basalt …

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 …

"Nickel saprolite ores are normally mined as feed to Fe-Ni smelters or Ni matte smelting operations. The smelting processes typically require high Ni cut-off grades of approximately 1.5 to 2.2% Ni, depending on the operation. These very high cut-off grades result in a significant portion of the saprolite profile being regarded as "waste" and hence …
