Iron removal from copper melt
Thread Content
As we all know, there are three methods for removing iron using zinc. But can they be applied to copper melt as well? Copper content is 10 g/L, iron is 8 g/L.
Manganese powder definitely works well for removal; I’ve used it before, but I’m not sure about other options
Iron can be removed by extraction. Copper extraction is carried out again.
It shouldn’t be possible; the pH for Cu hydrolysis is 2 units lower than that for zinc, resulting in greater losses during iron removal. Copper can be recovered through substitution or extraction methods
Is the pH value not allowed to be 1.5 in the iron yellow potash ferrihydrite method for zinc removal?
Copper can be displaced using iron powder for recovery.
I’m wondering what the original poster’s intention is 10 grams per liter for copper, 8 grams per liter for iron – is it obvious that copper is intended to be recycled? I’m not sure what system this is. Why not consider copper extraction first? Separating copper from iron isn’t difficult these days; there are plenty of copper extraction agents available. The original poster should clarify the system better, as well as state their intentions
Reply to 8# dengyg: What about the acidity of the system? This is quite crucial
Reply 9# crystalboyzjt: pH of 5~6 for neutralization and iron removal
