(PDF) Some factors that affect beneficiation of sulphide nickel–copper

The collectorless floatability of Enonkoski low grade ore (0.3% Ni) at alkaline and slightly acid pH after grinding in ceramic and steel mills is shown in Figs. 3 and 4. The sulphide minerals in nickel ores are easily floatable without a collector in acid pulp due to oxidation and, therefore, their separation is not possible at low pH.
