Optimum flotation conditions for recovery of the Cu and Ni from mine tailing were selected as 50 g/t PAX, 200 g/t MIBC, 10% pulp density at pH 6 for 6 minutes. Under these conditions, the recoveries of Cu and Ni were 82.76% and 29.89%, when grades of Cu and Ni were 2.09 wt% and 0.99 wt% respectively

16.1 ORE TYPES AND MINERALOGY. There are more than 45 different nickel minerals, but only a few are of economic importance. Table 16.1 lists some of the most important nickel minerals. Nickel, in various ores can also be found in other minerals, such as pyrrhotite and various cobalt minerals as an exsolution in isomorphic phases

Aug 15, 2018 The circuit being a sequential Cu-Ni flotation requires limiting the flotation of Ni into the Cu concentrate. This is achieved by using a Cu selective collector (Aerophine) and high pH in the final cleaning stage.
