Table 11.1 shows the points of zero charge (pzc's) for some iron oxides and quartz (Aplan and Fuerstenau, 1962).This property is important when using flotation collectors that are physically adsorbed, for example, amines. The pzc's for the three iron oxides, hematite, magnetite, and goethite, are around neutral pH (~ pH 7), whereas the …

The degree to which an iron ore is processed depends mainly on the iron ore products being made. The most common iron ores on the market are lump ore, sinter fines and iron ore pellets/pellet feed. Which products are suitable for a mine is dictated by the ore's liberation characteristics and market demands. Lump ore is generally between 7 and ...

Common Iron Minerals are magnetite (strong magnetic minerals), hematite (weak magnetic minerals), Limonite, specularite, siderite (all weak magnetic minerals). They are raw materials for the steel industry. The iron ore grade is low, many impurities. Therefore 80% above iron minerals need magnetic separation.
