Electronic goods are a major consumer of many critical metals, including copper, nickel, tin, zinc, lead, and precious metals. The processing end-of-life electronic equipment (E-Scrap) is becoming increasingly important to maintain the supply metals required globally, reduce environmental pollution. Currently, dominant route for E-Scrap pyrometallurgical processing, with first stage being reduc...

The purpose of this study was to increase the effectiveness slag cleaning in cast iron smelting process using an induction furnace. This resulted calculation terminal velocity emerging surface furnace based on Stokes' Law approach for each that appears during process. For casting, three samples were taken fastest time very light slag, slag’s heaviest and extreme comparison. results sample are t...

Roads are currently essential links of communication and economic development. However, these roads progressively requiring higher quality materials, implying a greater impact on the environment, in order to withstand high levels heavy vehicle traffic. Therefore, this research proposes use industrial by-products create bituminous mixtures which more resistant durable than traditional ones. The ...

The present paper illustrates an innovative steel processing route developed by employing hydrogen direct reduced pellets and open slag bath furnace. the reduction reactor as reductant on industrial scale. solution allows for production of from blast furnace transformed in reactor. are then melted furnaces, allowing carburization further refining. proposed is clean decarbonization industry. kin...

The effect of temperature on the equilibrium sorption of Pb 2+ from aqueous solution onto a low-cost electric furnace slag was investigated. In this paper, two-parameter isotherm models namely the Langmuir and the Freundlich and three-parameter isotherm model namely Redlich–Peterson were applied to describe the isotherms and to calculate their constants. The best estimation of the parameters of...

Xue, School of Material and Metalurgy, Northeastern University, Shenyang, China The titanium dioxide(TiO2) was prepared by efficient decomposition of titaniumbearing blast furnace slag (TBBFS) in molten salt system. The as-prepared TiO2 were characterized by X-r...
