Recovery from the electric furnace slag by magnetic separation To meet the target the following factors were investigated during magnetic separation tests grain size magnetic field intensity distance between material and magnet thickness of slag layer re grinding of coarse grains and moisture content 3 Experimental 3 1.Based on these considerations high temperature liquid liquid phase separation i e Teniente type reactor slag flotation and slag leaching methods technologies are discussed as specially applied in Chilean smelters Also a new approach based on material characteristics of both matte and slag i e magnetic separation is presented.
Feb 15 2018 OSTI GOV Journal Article New Slag for Nickel Matte Smelting Process and Subsequent Fe Extraction.May 12 2017 To decrease these losses it might be preferable to use a shredding magnetic separation step prior to smelting Test results in table 3 show that magnetic separation of shredded un incinerated scrap loses less than 2 percent of the copper and gold approximately 5 percent of the silver and about 40 percent of the palladium.
Copper mainly dwells in the slag in the form of bornite chalcocite chalcopyrite and metallic copper The rest are iron minerals like magnetic iron ore metallic iron and gangue like fayalite hedenbergite and amorphous phase matter Such slag can be concentrated by separation and enrichment to obtain copper concentrate.Magnetic separation and the reduction smelting method are used to recover and separate iron from copper slag Physical separation is an appropriate method for the recovery of iron from copper slag but the recovery rate with magnetic separation is lower by about 40 due to.
Centrator by magnetic separation was tamped to dense compaction followed by an 8 in layer of material composed of 90 pet crushed magnetite slag and 10 pet granular magnetite A 4 in veneer of fire clay brick was laid on a corbel inside the foundation wall for protection of the upper 30 in of concrete against furnace heat.Feb 28 2016 Separation efficiency between precious metals and slag is evaluated by taken slag samples and perform assays for gold and silver The performance depends on the charge properties gold and silver content and fluxes efficiency During the smelting process any residual mercury contained in the concentrate will be eliminated in the first moments.
Jun 15 2018 Generally above 75 m both dry or wet magnetic separation can be used while below 75 m wet magnetic separation is appropriate (Svoboda 2004) A combination of low and high intensity magnetic separation on a steelmaking slag has been shown to increase the Fe grade from 21 to 35 (Menad et al 2014).Feb 01 2018 than 50 pct of Fe containing phases are in the form of MgFe 2 O 4 when 15 pct CaO is added which is what we want because the MgFe 2 O 4 is much better for magnetic separation and reduction than the original (Fe Mg) 2 SiO 4 In this way Fe can be much easily extracted from residual slag and have multipurpose benefits.
Smelting of hemo ilmenite ore with anthracite coal Titania slag Minerals in titania rich slag ordered by decreasing mass densities Among other techniques the magnetic separation was the most efficient especially when performed on ground titania rich slags (Gue guin 1972 2004a) The separation was based on the following facts.The composition and the possible utilization of a slag sample from a nickel smelter operation in the Sudbury district were investigated The sample containing 0 136 Ni 0 10 Co and 0 29 Cu could be characterized as afayalite slag with a sulphide bearing glass matrix.
This smelter is 300 kt y it and entails concentrate smelting in one Teniente Converter (TC) of 4 x 15 m the converting of copper matte in two Peirce Smith converters (PSC) and the recovery of some valuable metals from slag in one electric slag cleaning furnace (SCF) Devia Parra Queirolo S nchez and Wilkomirsky 2019).The ferroalloy separation from the lumpy slag happens in a special process which is based on a gravity and magnetic separation The first stage of slag processing is crushing and sc reening the feed material to fractions of 0 4 and 4 22 mm Coarser fractio ns are handled by a heavy media separation the DWP method A magnet.
Slag recycling mainly the recovery of the precipitated magnetite crystals will be enhanced by controlling the slag cooling conditions In the present study using an infrared furnace the crystallization behavior of copper smelter slag with regard to obtaining a TTT diagram was assessed by X ray diffraction (using an internal standard.Of the existence of FeS The recovery body of copper slag was mainly copper matte returned to smelting process of copper by means containing acid leaching flotation recovery and depletion recovery 3 7 8) Copper slag con tains large amounts of fayalite direct magnetic separation of iron recovery is limited Recycling method for Fe is.
The density difference between silica manganese alloy and the slag is big enough to make gravity separation an ideal way to get the alloys Jigger is kind of gravity separator with its big handling capacity wide separation range and good separation efficiency It is widely used in smelting slag recycling instead of shaking table and other gravity separators.The recovery body of copper slag was mainly copper matte returned to smelting process of copper by means containing acid leaching flotation recovery and depletion recovery 3 7 8) Copper slag contains large amounts of fayalite direct magnetic separation of iron recovery is limited Recycling method for Fe is mainly roasting magnetic.
This work presents a semi smelting reduction and magnetic separation process for the recovery of iron and alumina slag from iron rich bauxite ore The effect of the process parameters on the recovery rate of iron maximum particle size of the iron nugget and the Al2O3 content of the alumina slag was investigated and optimized The results show that the iron nuggets and alumina slag can be.Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions without or with the addition of either ferric sulphate or hydrogen peroxide Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings Hydrogen peroxide was determined to be the best lixiviant.
Slag usually refers to a glassy by product of smelting ores to retrieve the metal I use the term here to also include any man made rock like by product of heating things to high temperature Thus clinkers are a form of slag Slags catch people attention because of their morphology Many slags contain metal from inefficient separation of.Oct 18 2020 metals from Cu smelter slag by a leaching process (Banza et al 2002 V tkov et al 2011) Yang et al (2010) reported the selective extrac tion of base metals such as Co Zn and Cu from Cu smelter slag at atmospheric pressure However the recovery and separation valuable metals such as Cu Fe Al Au and Ag from ﬁne materials.
