· The invention relates to a process to convert hematite powder into magnetite for heavy media separation providing known hematite powder which was characterized by a know particle analyzer; providing a micropelletiser; preparing pellets made from a mixture of hematite particles; coke fines and mill scales; drying of the pellets in an oven for about 12 hours at temperature around 120 C; .
· Hematite synthesis, characterisation and preparation of exposure dosages. To begin with, iron precursors (1 M FeSO 4 and 2 M FeCl 3) were mixed properly in deionised water (50 ml). Second, 10 ml of 20% w/v fresh garlic extract was added to the medium.

Hematite nanoparticles with average particle size of and nm were produced by mechanical grinding technique using planetary ball mill. The ground hematite were characterized by Xray diffraction analysis technique, specific surface area analysis (BET), transmission microscope (TEM) and scanning electron microscope (SEM). The effects of different properties of hematite particles used ...
Iron lathe waste powder has the potential as a raw material in the synthesis of hematite pigments. Hematite pigments have many advantages, one of which is antiswelling properties that can maintain the dimensions of wood. Hematite pigment synthesis was carried .
Mill scale is one of waste materials which is produced as a result of hot rolling of steel in all steel companies. On the other hand, mill scale is considered a rich iron source with minimum impurities. This work aims at conversion of mill scale by adjusting smelting processes to produce different valuable products. The smelting processes were carried out using carbothermic reduction in a ...
Mill scale iron waste has been used to prepare some iron oxide pigments via specific precursors. Magnetite and goethite were precipitated from their respective precursors in aqueous media. Various red shades of hematite were prepared by the calcinations of the precipitated goethite at temperatures ranging from 600 to 900 °C.
The specific gravity of waste rock can be expected to range from to for most rock types and from to for waste rock from iron ore and taconite minings. Mill Tailings The grain size distribution of mill tailings can vary considerably, depending on the ore processing methods used, the method of handling, and the loion of the sample relative to the discharge point in the tailing ...
