The Feed-forward artificial neural networks with 5-8-7-7-4 and 5-8-8-6-4 arrangements were used to predict the grade of final iron concentrate of Gol-E-Gohar iron ore plant. 3. The neural network was trained using early-stop training to acquire a good generalization property.
The artificial Fe 2 O 3 particles as well as the Hualian iron ore concentrate were used in the precipitation experiments. Fe 2 O 3 lumps were obtained by roasting reagent grade Fe 2 O 3 fine powders for 48 h at 1473 K. After crushing and sieving, the particles of size between 100–150 mesh were chosen as the raw material. The Fe 2 O 3 and Hualian iron ore particle morphologies are shown in ...

Jan 21, 2016 Optimization of iron ore sintering process is to maximize the productivity and the sinter ore quality while minimizing the energy consumption. However, these economic and technical criteria are sometimes contradictory and the improvement of one criterion generally leads to the deterioration of other criteria. This paper aims to seek the optimal manipulated parameters from the production data ...
Dec 21, 2020 The monomer open-pit iron ore mine currently has an annual production capacity of 13 million t/a of iron ore. Due to the complex engineering geological conditions, the development of joints, the accumulation of boulders on the slope surface, and the influence of blasting and excavation, the lower slope of the Nanfen open-pit iron mine did not ...

The primary motivation of this work is to evaluate a new alternative ironmaking process which involves the combination of a Rotary Hearth Furnace (RHF) with an iron bath smelter. This work is concerned primarily, with the productivity of the RHF. It is known that the reduction in the RHF is controlled by chemical kinetics of the carbon oxidation and wustite reduction reactions as well as by ...
