Visokotemperaturno procesiranje in reciklaža avtomobilskih katalizatorjev [PDF]
, 2018 This paper presents the results from an experimental study of the thermal method applied for obtaining platinum-group metals (PGMs) by melting used autocatalysts in an 80 kVA plasma reactor, using suitable fluxes and a reducing agent. As the collector of

Investigations of nickel (II) removal from aqueous effluents using electric arc furnace slag [PDF]
, 2013 The tendency of electric arc furnace (EAF) slag to the adsorb nickel(II) from aqueous solution has been investigated through batch experiments. Scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR) and Energy Dispersive X-Ray

steel research international, EarlyView.This study uses coupled computational fluid dynamic‐discrete element method (CFD–DEM) simulations to investigate biomass particle injection through a shrouded lance in electric arc furnaces (EAFs). It examines how biomass properties, feed rate, and lance design affect particle dispersion and delivery efficiency.

Development of Slurry Surfacing with Electric Arc Furnace Slag for Pavements with Friction Problems [PDF]
, 2020 Pavement maintenance is an essential activity for maintaining the quality of the pavements. It is common for the ageing pavement to present problems of friction, so a proper solution must be provided.

steel research international, EarlyView.The melting behavior of hot briquetted iron (HBI) is observed and compared with FactSage computing simulation. When using HBI in an electric arc furnace process, a proper design of intrinsic carbon content in HBI, charging ratio of HBI, and addition of lime are proposed to be essential to control the slag volume, maintain slag basicity, and mitigate ...
