G. SIWIEC et al.: BEHAVIOUR OF IRON DURING REDUCTION OF SLAG OBTAINED FROM COPPER FLASH SMELTING As shown in previous studies [14-15], intensifica-tion of iron oxide reduction does not take place until the copper content in the slag id decreased to less than 0,6 %mass, which was successfully confirmed by the obtainedBehaviour of iron during reduction of slag,As a result, a Cu-Pb-Fe alloy is obtained and subjected to the converting process along with waste slag which contains ca. 0,5 % mass Cu. The article presents an analysis of results of the research on behaviour of iron in the course of slag reduction where diverse fine-grained carbon-bearing materials function as reducers.BEHAVIOUR OF IRON DURING REDUCTION OF,As a result, a Cu-Pb-Fe alloy is obtained and subjected to the converting process along with waste slag which contains ca. 0,5 % mass Cu.

behaviour of iron during reduction of slag obtained from copper flash . Jun 20, 2014 For instance, slags generated during copper production are not only pro cessed for recovery of this particular metal but also for lead, iron etc. . During a technological process of copper production in the flash smelting furnace at.Slag and its Role in Blast Furnace Ironmaking |,Slag and its Role in Blast Furnace Ironmaking.,slag is produced during the production of,by the extent of reduction of iron oxide,Simulation of Primary-Slag Melting Behavior in the,,operation, the behavior of the primary melt, which is formed in the sinter at the cohesive zone of the blast furnace, has been simulated by dripping slag through an iron or oxide funnel. The effects of basicity, Al2O3, and FetO contents in the five slag systems on the dripping temperature and weight of slag remaining on the funnel have been discussed.

study the interactions between liquid slag and graphite. Steelmaking slag was used during this research. The slag used included converter slag and slag from chrome steel melting as well as their mixtures with other modiﬁers. The analysis covered six types of slag in the temperature ranging from 1100 C to 1600 C in the argon atmosphere.Reducibility and reduction swelling behaviour of some iron,,Iron ore pellets are used for the production of hot metal in blast furnaces and DRI/HBI in direct reduction processes. A blast furnace is a shaft furnace, which is charged with iron bearing materials (pellets, sinters and/or lump ore), reducing agents (metallurgical coke) and additives (limestone, quartz, BOF slag).Metal-slag Separation Behaviors of Pellets,But none of them focused on the metal-slag separation behavior of the slag region ‘d’ which can be practically important to use high Al 2 O 3 ore for CCA reduction process.
The slag must have the affinity for absorbing impurities i.e. gangue from charge along with other deleterious impurities which affect the quality of hot metal. It is essential to know the behaviour of slag in terms of the chemical composition, the mineralogical constitution and its ability to react and trap the minor impurities.TABLE of CONTENTS Advances in Molten Slags, Fluxes,,TABLE of CONTENTS Advances in Molten Slags,,Optimized Slag Design for Maximum Metal Recovery during,Reduction of Iron Oxides in Mould Fluxes,Influence of Reduction Temperatures on, V.
