effects of basicity and mgo in slag on the behaviors of smelting vanadium titanomagnetite in the direct reduction Electric Furnace Process
Metals, 2016Co-Authors: Tao Jiang, Shuai Wang, Feng Chen, Fuqiang ZhengAbstract:The effects of basicity and MgO content on reduction behavior and separation of iron and slag during smelting vanadium titanomagnetite by Electric Furnace were investigated. The reduction behaviors affect the separation of iron and slag in the direct reduction-Electric Furnace Process. The recovery rates of Fe, V, and Ti grades in iron were analyzed to determine the effects of basicity and MgO content on the reduction of iron oxides, vanadium oxides, and titanium oxides. The chemical compositions of vanadium-bearing iron and main phases of titanium slag were detected by XRF and XRD, respectively. The results show that the higher level of basicity is beneficial to the reduction ofiron oxides and vanadium oxides, and titanium content dropped in molten iron with the increasing basicity. As the content of MgO increased, the recovery rate of Fe increased slightly but the recovery rate of V increased considerably. The grades of Ti in molten iron were at a low level without significant change when MgO content was below 11%, but increased as MgO content increased to 12.75%. The optimum conditions for smelting vanadium titanomagnetite were about 11.38% content of MgO and quaternary basicity was about 1.10. The product, vanadium-bearing iron, can be applied in the converter steelmaking Process, and titanium slag containing 50.34% TiO2 can be used by the acid leaching method.

ferronickel preparation from nickeliferous laterite by rotary kiln Electric Furnace Process
Characterization of Minerals Metals and Materials, 2016Co-Authors: Hao Jia, Jun Luo, Zhiwei Peng, Yuanbo Zhang, Tao JiangAbstract:Nickel is an important strategic metal, which is mainly used for stainless steel production. In the recent years, ferronickel has been used as a substitute for electrolytic nickel for alleviating the cost of stainless steel production. Rotary kiln-Electric Furnace (RKEF) smelting is currently the world-wide mainstreaming Process for ferronickel production from nickeliferous laterite ore, in spite of the high power consumption. In this study, aiming to provide some meaningful guidance for ferronickel production of RKEF smelting, reductive roasting followed by smelting Process was carried out. The conditions including reducing parameters (roasting temperature and time) and smelting parameters (coke dosage, CaO dosage, melting temperature and time) were ascertained. The metal recovery ratios, as well as Ni, Fe, S and P content of ferronickel were considered. The results showed that a ferronickel containing 10. 32 wt. % Ni was obtained from a laterite with 1. 85 wt. % Ni, the nickel recovery ratio was about 99%.

Road Performance of Concrete Incorporating Manganese Slag
Advanced Materials Research, 2011Co-Authors: Duo Qiang Liang, Feng Qin, Ji Bo JiangAbstract:It’s of great importance to innocuity, minimization and reutilization of manganese slag generated in manganese product by Electric Furnace Process. In the paper, ordinary Portland cement was incorporated by manganese slag, and then mechanical tests were performed to obtain the fundamental properties of the cement stabilized material in order to analyze the road performance of cement stabilized layer. The obtained experimental results showed that the manganese slag cement replaced by 2~6%( wt) manganese slag has better road performance such as mechanical properties, hydro-abrasive erosion and chemical corrosion resistance.

Mechanical Performances of Concrete Made with Manganese Slag
Applied Mechanics and Materials, 2011Co-Authors: Duo Qiang Liang, Feng Qin, Ji Bo JiangAbstract:It is of great importance to innocuity, minimization and reutilization of manganese slag generated in manganese product by Electric Furnace Process. In the paper, ordinary Portland cement was replaced partly by manganese slag to then evaluate manganese slag’ effect on mechanical performances of them. The experimental results obtained show that ordinary Portland cement added less than 30% by manganese slag was improved in mechanical performances and the cement concrete added less than 30% by manganese slag was not changed significantly. To lower economic cost and achieve enhanced mechanical performances, manganese slag can be substituted partly to cement concrete.
