Abstract Jarosite sludge coming from the hydrometallurgical zinc production route is a hazardous material, which currently neutralized and landfilled by so-called Jarofix® process. The present study aims to assess mechanical metallurgical properties of briquettes made jarosite powder with blast furnace sludges, acting as reductant recover iron oxide in form pig produce an inert slag, increasing...

There is a growing drive within the steel industry to increase scrap usage in Blast Furnace (BF)-Basic Oxygen (BOF) integrated route and extend scrap-based Electric Arc (EAF) for production due resultant reduced energy costs CO2 emissions abundant supply UK. In general, may contain high levels of undesirable residual elements, which have pronounced effects on casting process production. This ar...

A literature review of studies and researches has been attempted in the field of dissimilar metal welding. Dissimilar metal welds have numerous industrial applications in area of thermal power generation, chemical, petrochemical, automobile, aerospace industries and nuclear plants etc. The purpose of this paper is to review: (a) Dissimilar metal welds, their Metallurgical and Mechanical aspects...

Within the framework of the European Metrological Research Program (EMRP) IND04 MetroMetal 'Ionizing radiation metrology for the metallurgical industry', joint research carried out by 14 metrological institutions from countries within the European Union and the company ENVINET, questions concerning the determination of radioactivity in samples relevant to the metallurgical industry were resolve...

The cement industry is facing the challenge of a lack supplementary cementitious materials substituting clinker. This applies primarily to granulated blast furnace slag, most commonly used as main component cements, due changes in metallurgical industry, and siliceous fly ash abandonment fossil fuels world. A potential new common cements may be calcined marls, which are available large quantiti...

the estimation of metallurgical parameters of flotation process from froth visual features is the ultimate goal of a machine vision based control system. in this study, a batch flotation system was operated under different process conditions and metallurgical parameters and froth image data were determined simultaneously. algorithms have been developed for measuring textural and physical froth ...

Abstract In this work, fire simulations were carried out on AISI 316 austenitic stainless steel sheets (similar to EN X5CrNiMo17-12-2), usually employed for the production of flue pipes. The thermal alteration induced by was simulated heating samples at different temperatures (from 20°C 1050°C) and exposure times (1 h 6 h) in a laboratory furnace. metallurgical investigation concerned surface c...

In this paper, a new iron-carbon micro-electrolytic filler for wastewater treatment was prepared using the blast furnace dust. The effects of preparation conditions on performance during were investigated. optimal obtained, which provided an experimental theoretical basis use metallurgical dust sludge in fillers. From results treating methyl orange-simulated with fillers different conditions, i...
