    The chemical composition of copper slag varies with the type of furnace The typical composition of smelting slags is Fe (as FeO, Fe 3 O 4) 30–40%; SiO 2 35–40%; Al 2 O 3 up to 10%; and CaO up to 10% The density of copper slag varies between 316 and 387 g/cm 3 based on the amount of iron content The average specific gravity of copper slag is about 35 g/cm 3, which01/05/2006· Secondary copper blast furnace slag was treated with carbon to derive the conditions for maximum recovery of copper with minimum simultaneous reduction of iron oxide Experiments were carried out to study the effects of parameters such as temperature, carbon addition and CaO addition to the slag on the efficient recovery of copper A twostageRecovery of copper from copper blast furnace slag03/02/2021· Recovery of copper in concentrates from slags cooled in the induction furnace and ground for 30 minutes ranged from 871 to 962 percent with the best recovery obtained on the highest grade slag sample Copper content of the flotation tailings, which is the most important indicator, ranged from 026 to 039 percentHow to Recover Copper from Slag by Flotation

    21/09/2012· During the last few decades, the pyrometallurgical processes used for cleaning copper smelting slags have been steadily optimized The electric furnace or rotary slagcleaning furnace are now generally used to perform this task, giving a level of copper in discard slag typically in the range of 055 wt% and 13 wt%, with most plants reporting copper losses inKeywords: slag cleaning, stirring mode, copper slag, submerged arc furnace, stirring reactor Abstract Slags resulting from pyrometallurgical copper processes are important byproducts to be controlled in structure and composition Due to the significant volumes of slag compared with those of the target metal it is mandatory – as already practiced today – to use the slag as aImproving Copper Recovery from Production Slags byslag depletion and lead to significant irreversible losses of metal with slag Therefore, ways to reduce the loss of copper with slag in the process of autogenous smelting are becoming increasingly important today RESEARCH METHODOLOGY The samples of the slags were obtained from Vanyukov furnace in Balkhash CopperSmelting Plant TheyTHE MAIN REASONS FOR INCREASED COPPER LOSSES WITH

    Flash furnace slag is treated in a slag cleaning furnace with coke or iron sulfide Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide The copper sulfide is removed and the remaining slag is discarded Converting produces blister copper by eliminating the remaining iron and sulfur present in theA copperslag from the waterjacket furnace, producing coppermatte, containing copper and other base metals was used for copper recovery This slag was provided by Gecamines from the Democratic republic of Congo Raw PKS samples were provided by artisanal palm oil producers from the Democratic Republic of Congo Lime from the metallurgy laboratory of the UniversityINVESTIGATION ON POSSIBLE USE OF PALM NUTSHELLS ASThe copper slag cleaning in an electric furnace is based on slag reduction and settling of copper matte inclusions Copper recovery depends on the slag temperature, degree of magnetite reduction and slag residence time The formation of solid buildup on the furnace hearth leads to the decrease of furnace volume and slag residence time, affecting copperMECHANISM OF BUILDUP FORMATION IN AN ELECTRIC FURNACE
