To obtain the magnetite from ilmenite, iron(III) solution leachate from an acid hydrothermal process was used as a precursor. 19 The concentration of iron(III) in the leachate was determined by atomic absorption spectroscopy (Varian 240 FS). Based on the concentration of iron(III), the solution was mixed with a potassium iodide (Sigma-Aldrich

In most samples, magnetite turned out to be a better catalyst in combination with metallic iron than hematite, but the differences in COD concentration in the purified compounds were not significant. The fastest TOC removal was observed during the first 15 min of the process.

In the magnetite iron ore pelletization process, oxidation of magnetite followed by sintering of the oxidized magnetite (hematite) is desirable. Optimum preheating time & temperature and roasting time & temperature is required to get the desired properties of the pellets with magnetite, hematite, and hematite–magnetite blend.

Iron Ores (Hematite and Magnetite) Iron is a metal from the periodic table’s first transition series and group 8. It is the most common element on Earth by mass, just ahead of oxygen (32.1 % and 30.1 %, respectively), forming much of the Earth’s outer and inner cores. It is the fourth most abundant element in the crust of the Earth.

Extraction of Iron from Hematite 1). Concentration. Hematite is concentrated by the gravity separation process which is a method based on the difference in specific gravities of the metallic ore and gangue particles. The oxide being heavier settles to the bottom while lighter impurities come to the surface and are removed.

Hematite and magnetite are by far the most common types of ore. Pure magnetite contains 72.4 percent iron, hematite 69.9 percent, limonite 59.8 percent, and siderite Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine.

Even 5% of CO was sufficient to convert hematite into magnetite, which resulted in an increase in magnetization up to 85 Am 2 /kg. The kinetic analysis indicated that the reduction of hematite to magnetite is a single-step process, which can be described using the first-order reaction model.
