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.

New Slag For Nickel Matte Smelting Process And Subsequent

New Slag For Nickel Matte Smelting Process And Subsequent

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.

On The Utilization Of Nickel Smelter Slags

On The Utilization Of Nickel Smelter Slags

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.
