We transform steelworks waste from headache into incom generating asset Unique metal recovery technology.Recovery of Cobalt and Copper from Nchanga Mines Slagproduced in this process is also laundered to an anode furnace for further refining and casted into anod The SCF slag is processed for copper cobalt recovery to produce a copper cobalt iron alloy in the cobalt recovery furnace (CRF) The CRF process aims to obtain a final slag of approximately.Jigging recovery of chromium slag process of ferrochromeFerrochromium alloy chromium slag dissemination size is uneven thickness, maximum can up to about 30mm, the minimum is below 1mm, in order to recover as much as possible the ferrochrome, ferrochrome often need to crushing, grinding, recovering jigging process, because the chromium iron alloy high price of coarse grained and fine grained, ferrochrome prices are low, so need to early recovery of.RESOUR CE PA CK Iron Mining and Processing in South AfricaIron Mining and Processing in South Africa RESOUR CE PA CK Iron Mining and Processing in South Africa , Pig iron Slag Iron Ore (65% Fe) The ore undergoes a series of crushing steps to reduce the particle , process Underground mining Recovery smelting Extraction removing gold from solution.SLAG AGGREGATES PRODUCER WLLProcessing Iron Slag and producing steel skull scrap and different sizes of slag aggregates and powders LIME STONE Processing Limestone & producing good quality Limestone aggregates , sub bases, Sub grades , filling materials and boulders for road and construction industry.Slag Heat RecoveryIn modern blast furnaces around 025 030 tons of liquid slag with a temperature of approximately 1450°C are produced per ton of pig iron A number of slag heat recovery systems have been proposed However none have yet been applied commercially due to technical difficulties that arise in the development of a safe, reliable and energy efficient system.US20150000467A1The present invention provides a method of separating and recovering iron from a waste non ferrous slag, generated in a process for smelting of non ferrous metals, including copper, zinc and lead, in which a reducing agent and a reaction catalyst are added to the crushed waste non ferrous slag, and the mixture is subjected to a reduction reaction, thereby converting amorphous iron oxides.
RECOVERY OF PIG IRON FROM COPPER SMELTING SLAG BY REDUCTION SMELTING Copper slag is a by product obtained during smelting and refining of copper Copper smelting slag typically contains about 1 wt% copper and 40 wt% iron depending upon the initial ore quality and the furnace type Main components of copper slag are iron oxide and silica.
Recovery of iron and removal of hazardous elements fromNov 20, 2016· Furthermore, copper slag is mainly composed of the fayalite (2FeO⋅SiO 2) phase, which means that iron could potentially be recovered from waste copper slagThus, we proposed adding a reduction stage as an additional step to the conventional copper smelting process in order to achieve both removal of hazardous elements and recovery of iron from waste copper slag in the present study.recovery of ferrochrome from steelmaking slagiron recovery from slag processing
