Study on Extracting Copper from Copper,Zinc and Iron Solution

The domestic extractant N902 was adopted to extract Cu2+ from the copper,zinc and iron polymetallic leaching solution,investigating the influences of extractant concentration,extraction phase proportion,oscillation time and extraction temperature on the extraction rate of copper.On the relatively good condition,3 stage counter current extraction was carried on for the copper,zinc and iron solution,the content of which was 20.18g/L and 30.38g/L.As a result,the extraction rate of copper was 98.65% and 96.50% ...
