This study puts forward a new method to separate phosphorus and iron from high-phosphorus oolitic hematite through iron nuggets process. Firstly, the physical, chemical, and microscopic characteristics of high-phosphorus oolitic hematite are investigated. Then, the reaction mechanisms of high-phosphorus hematite together with feasibility to separating …
The hematite process and the iron phosphate process were compared at different levels of pH and temperature with and without seeding. Experiments were conducted to validate the effect of the solution pH, the solution temperature and seeding on the precipitation of iron(III) and the resulting losses of nickel and copper.
The VIKOR method of compromise ranking determines a compromise solution, providing a maximum "group utility" for the "majority" and a …
The whole production line of hematite ore processing is composed of raw ore processing, shaft furnace roasting, grindings, and magnetic separation production phases. Their automation systems consist of the process control part and the operational optimization system. The target of the optimal operational control is to optimize the concerned operational indices, …

An attempt has been made to utilise hematite ore fines in the form of briquettes with two different form of mixing i.e. intermixing and multilayered by means of carbothermal reduction along with boiler grade coal and coke dust. The influence of reduction temperature (1323, 1373 and 1423 K) and reduction time (10, 20, 30, 45 and 60 min) has been …
be purely hematite by different physical characterization techniques. Analyzing the TG profile, a reaction pathway of the decomposition process leading to hematite is proposed. 2 Experimental The molecular material {As(C6H5)4[FeIIFeIII(C2O4)3]}n (hereafter, AsFeFe-O)was prepared in a one-pot reaction following the literature [13]. The powdery ...

We present the process of synthesis and characterization of magnetite-maghemite nanoparticles by the ball milling method. The particles were synthesized in a planetary ball mill equipped with vials and balls of tempered steel, employing dry and wet conditions. For dry milling, we employed microstructured analytical-grade hematite (α …

An ore is a mineral deposit that contains a metal that can be extracted using existing technological methods. Iron can be extracted from two types of iron ores: Magnetite and hematite. Magnetite is composed of iron in the form of Fe 3 O 4. Hematite is a mineral that contains iron in the form of Fe 2 O 3.
Magnetic Separation Method Mineral Processing Metallurgy The most striking results were for the sand fraction where the separation segregated almost all theic minerals in theic fraction. In the soils derived from mafic rocks, in general, the values ofization in theic fraction varied from 7 to 120 times theization values in theic fraction.
This study compares the performance of the iron phosphate precipitation process with that of the hematite process at different operating temperatures (40 °C–90 °C), pH conditions (pH 1–pH 3) and seeding measures for the removal of iron from a chloride leach solution. The extent of iron removal, co-precipitation of nickel and copper, and ...
