SX Solvent Extraction Process Principles Theory

Feb 01, 2017 It is important for the reader to understand that solvent extraction is only one unit process in a series of unit processes needed to win metal from ore. For this reason solvent extraction must be compatible with, and complimentary to, the leaching process which precedes it and the final metal recovery process which follows (Figure 1).

Zinc solvent extraction impurity and entrainment

Some observations based on previous experience with Cyanex 272 in solvent extraction and zinc extraction with D2EHPA both using ammonia gas for pH control. Is the NaOH added to the organic phase prior to mixing with the aqueous? This seemed to work best with ammonia gas, and avoids precipitation of solids that can stabilise the saponified C272.
