The best separation method for nickel-magnesium solutions
Thread Content
My solution contains 20–30 grams per liter of nickel and 2–8 grams per liter of magnesium; how can nickel and magnesium be separated more effectively from this solution? Nickel is intended to be converted into nickel sulfate; which method, 204 or 507, is more effective for extraction?
Both extractants are used to extract magnesium, while nickel remains in the raffinate
As far as you know, is there any better method for separating magnesium and nickel?
This concentration of yours basically means it has been extracted
We specialize in resin adsorption; the resin method can also be used to separate nickel and magnesium. We can exchange ideas on this topic
Does resin exchange absorb magnesium ions or nickel?
Initially, the resin adsorbs both nickel and magnesium simultaneously. However, as it becomes saturated with these ions, nickel displaces magnesium; magnesium ends up in the effluent, while nickel accumulates on the resin. We have conducted such experiments for Jinchuan
Okay, thank you. Is what comes out a nickel sulfate solution? What are the approximate concentration and acidity levels?
It is a nickel sulfate solution, with a nickel ion concentration of over 30 g/l, a nickel-to-magnesium ratio of greater than 10:1, and a sulfate concentration of less than 50 g/l
Extraction and separation are appropriate. We can keep the magnesium content in the nickel sulfate residual solution below 0.005 g/L.
