“Synthesis and Characterization of Titanium Slag from Ilmenite by Thermal Plasma Processing” by Sneha Samal. Instead, pyrometallurgical processes appeared promising in the metal recovery. It was found that a strong reducing slag containing 70wt% CaC2 and 30wt% CaF2 was most suitable for the simultaneous removal of phosphorus, sulphur and arsenic without incurring a significant loss of valuable metal elements. The first is desulfurization of steel in ladle metallurgy where the equilibrium driving force is changing with time, Thermo Scientific™ ARL™ QUANT’X EDXRF Spectrometer. All calibration functions, curve display and fit evaluations are included in the standard software package supplied with the ARL QUANT’X Spectrometer. In slag metallurgy, molten slag properties, such as electrical conductivity, are important for determining the process parameters for alloy production. With this slag, more than 70wt% sulphur, 67wt% arsenic, and about 30wt% phosphorus were removed. Choi and Lee's dynamic wetting model was evaluated and found to not only represent the data well but have physical relevance for the basic, but not the acid, slags investigated. volume 68, pages2313–2315(2016)Cite this article. These demands are being met by advances in our knowledge of the chemical, physical, and thermal interactions between steel, gas, slag, and refractory phases which take place within individual reactors as well as during transfer between reactor and the next. Part of Springer Nature. By the rapid plasma process, pig iron containing 98.8% Fe and slag containing 84.5% TiO2 were successfully separated from ilmenite subjected to pre-reduction at 1200°C. In order to assess the attainable accuracy, two procedures for the determination of montmorillonite contents are tested. It introduced a model for estimating electrical conductivities of multi-component slags in which the relationship between electrical conductivity and the temperature of the slag was described by the Arrhenius law. In order to use this nickel for the production of stainless steel or nickel alloys, the phosphorus, sulphur and arsenic in the material must be removed.

In this chapter, the reader will find details about the formalisms of the most utilized Gibbs energy models used in thermodynamic computer models. Slag Metallurgy and Metallurgical Waste Recycling, http://link.springer.com/journal/11837/68/9/page/1, https://doi.org/10.1007/s11837-016-2047-2. This study highlights the importance of mineralogical characterization in the selection and optimization of process parameters for slag treatment. In the third article, entitled “Mineralogical Characterization of Copper Slag from Tongling Nonferrous Metals Group China,” Tiejun Chun et al. Copper slag originating from the copper smelting industry is worthy of particular attention due to its massive generation and enrichment of multiple valuable metals. 9). The results were also supported by the calculated and simulated related liquidus temperatures and phases diagrams of the fayalite-type slag. However, when one or more lines overlap the line of interest, or a complex background is present, profile fitting techniques are required in order to eliminate. In the petroleum industry catalysts are often used to accelerate the reaction rate and remove the hazardous sulphur and arsenic from crude oil. In the fifth article, entitled “Synthesis and Characterization of Titanium Slag from Ilmenite by Thermal Plasma Processing,” Sneha Samal disclosed the advantages of thermal plasma processing of ilmenite for production of titania-rich slag. About 25% of these are other metals & metal products. Titanium-rich slag is another waste product that has emerged as an indispensable raw material for many titanium uses due to the lack of natural Ti-bearing resources. This project examined the feasibility of using flux modification to reduce the as-deposited hydrogen content of basic-type shielded metal arc welds. Energy Mater. The fact that there are intrinsic problems in evaluating the optical basicities for the transition metal oxides is acknowledge, and a new scale is recommended. Such importance has been partially revealed by the results reported in the seventh article entitled, “Estimation Model for Electrical Conductivity of CaF2-CaO-Al2O3 Slags” by Guan-Yong Shi et al. To evaluate the spectrometer’s repeatability, tests were performed to show the typical precision achieved by the ARL QUANT’X Spectrometer for a 3-minute total counting time. Slag is a typical byproduct generated during high-temperature metallurgical processes. The hydroxyl capacity, C OH , is therefore given by Equation. “Mechanism of Mineral Phase Reconstruction for Improving the Beneficiation of Copper and Iron from Copper Slag” by Zhengqi Guo, Deqing Zhu, Jan Pan, and Feng Zhang. P. Drissen, A. Ehrenberg, M. Kühn, and D. Mudersbach, Steel Res. In the sixth article, entitled “Reduction Kinetics of Electric Arc Furnace Oxidizing Slag by Al-Fe Alloy,” Jaehong Lee et al.
