Upgrading nickel in laterite ores by flotation
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 ...
Copper Nickel Flotation
The Bureau of Mines investigated the flotation responses of two copper nickel ore samples from the Duluth Complex with the objective of recovering bulk sulfide concentrates. One of the ores studied was taken from a test pit; the other was taken from a test shaft. The samples were quite similar except that the pit sample analyzed 0.35 pct Cu and 0.11 pct Ni and the shaft …
Selective sulphidation and flotation of nickel from a nickeliferous
The absolute nickel recovery is based on the total nickel content of the ore, while the recoverable nickel is based on the amount of nickel sulphide present after sulphidation. The overall economics and suitability of the process relies on the total nickel recovery, whereas the flotation performance should be assessed on the recoverable nickel ...
