Molecular dynamics simulation of siderite-hematite-quartz

It is essential to investigate flotation behavior of siderite-hematite-quartz for processing those iron ores. To this end, flotation of the three pure minerals was carried out in sodium oleate system in this work. Flotation theory mainly consists of flotation solution chemistry, interfacial chemistry and flotation kinetics . All the parameters

Flocculation and flotation characteristics of fine

Flocculation and flotation characteristics of fine hematite with sodium oleate have been investigated through electrophoretic mobility, surface hydrophobic properties, adsorption measurement, flocculation and flotation experiments. A clear region of flocculation can be obtained over a wide pH range depending on oleate concentrations. Increasing the oleate concentrations results in more stable

Quartz-Calcite-Hematite System Flotation

Unleached hematite responded readily to sodium oleate and gave good flotation in alkaline pulps, (Figure 2), when the mineral surface was negatively charged. This would seem to rule out an electrostatic model, which is the mechanism normally believed to be operative in the case of leached hematite. A recent investigation by Peck et al., on two unleached hematite specimens has shown that
