Generally nickel cobaltite is a pure spinel oxide material in which nickel ion occupies the octahedral site and cobalt is distributed over both octahedral and tetrahedral sites and is expected to show better redox chemistry than the two single component metal oxides due to the synergistic contribution from nickel and cobalt ions

For depressant kaolinite interactions it was found that selective depression of hematite against kaolinite largely depends on strict pH control in iron ore flotation circuits and the level of ionic strength in iron ore flotation pulp The presence of calcium and magnesium is particularly detrimental to kaolinite removal from iron ore [32]
