An Overview Of Recovery Of Metals From Slags Sciencedirect

Jan 01 2003 Therefore the basicity of AOD slag is lower than steel slag. Moreover AOD slag contains much less iron than steel slag. Hence recovery of iron from AOD slag is not important. Perhaps the most important characteristic of AOD slag is that it contains a high amount of Cr 2.54.3 and some Ni 0.20.45.

Pyrometallurgical Recovery Of Iron From Iron Silicate Slags

While it has long been known that substantial quantities of iron have been lost through the discarding of slags e.g. copper smelter slags the lack of an economical recovery process as compared to other sources of iron has prevented the commercial acceptance of iron recovery from such slags.

Recovery Of High Grade Iron Compounds From Ld Slag By

Jan 10 2014 The fraction free of iron scraps obtained from this flow sheet is considered as representative sample for further tests to recover the high grade iron from LD slag. Download Download full-size image Fig. 4. Flow sheet of recovery of iron compounds during the sampling of LD slag.

Iron Recovery From Discarded Copper Slag In A Rhf Direct

By using DR followed by a magnetic separation process for iron recovery from copper slag Yang obtained iron powder of 92.05 iron content with an iron recovery rate of 81.01 and Wang obtained iron powder of 92.96 iron content with an iron recovery rate of 93.49. Both of their tests have achieved good results.

Recovery Of Iron From Leadzinc Metallurgical Slags By

Apr 12 2015 The recovery of iron from iron sinking slag and lead smelter slag was investigated by desulfurization-reduction bath smelting. The effects of lead smelter slag LSS to iron sinking slag ISS mass ratio and temperature were investigated in desulfurization experiments.

Recovery Of Iron From Copper Flash Smelting

million tons are historically cumulated. Copper slag contains iron in the range of 42 to 45 which can be recovered and recycled along with the contained copper to obtain an iron-copper alloy and a final slag rich in oxides. Therefore the present work shows the experimental

Enrichment Of Fecontaining Phases And Recovery Of Iron

Jan 13 2012 Subsequently wet magnetic separation was conducted to examine the relations between iron recovery ratio and cooling conditions. The results show that the slags under the four cooling conditions mainly contained dicalcium silicate RO phase Fe t O 2CaOFeAl 2 O 3 and calcium ferrite.
