METHOD FOR CONTROLLING THE PRECIPITATION OF ALUMINA |
摘要 |
<p>A method for controlling the precipitation of alumina from Bayer process solutions, the method comprising the steps of: contacting the Bayer process solution with a substantially water- immiscible solution comprising an extractant; extracting at least a portion of the metal cations present in the Bayer process solution into the substantially water-immiscible solution; thereby reducing the concentration of hydroxide ions in the Bayer process solution.</p> |
