adsorption of oleic acid on iron ore

iron ore using oleic acid or its soaps is usually performed in a strongly alkaline environment ie above pH 11 Fuerstenau and Cummins 28 concluded that when oleate was used as collector the suitable by adsorption of multivalent ions to reverse its surface charge from negative to positive The most
