THE MOST ADVANCES TECHNOLOGY IN SLAG PROCESSING
Ecofer’s third generations slag processing and Fe metal recovery process has been developed to respond to stricter environmental regulations.
The Fe metal recovery capacity can reach up to 99% and the purity of recovered Fe metals are +80%.
For example, when the mass of feed material is 1000 kg and metallic iron content is 12% and fraction size 0-60 mm, recovery can be as following:
From 12 % of Fe the recovery will be 99% /118,8 kg which is divided as in table below :
From 25 % of FeO the recovery will be 70% which is around 250 kg.
The production cost average 0,30 EUR per processed ton, depending local cost of electricity.
Income sample based on scrap price 200 USD and Fe concentrate price 65 USD per ton:
|Fraction||Amount||Fe content||Sales price||Total|
|0 – 1 mm||250,0 kg||+60% FeO||50 EUR/ton||12,50 EUR|
|1 – 20 mm||100.0 kg||+80% FeM||100 EUR/ton||10,00 EUR|
|20 – 60 mm||42.0 kg||+90% FeM||150 EUR/ton||6,30 EUR|
|Grand total||28,80 EUR|
The slag tailing will be left at 640 kg which is divided as following:
0 – 1 mm 500 kg
1 – 4 mm 100 kg
