Abstract
SAMIM—Centro Ricerche Veneto has investigated the possibility of extracting arsenic by an aliphatic long-chain alcohol according to a solvating mechanism without adding any other completing or solvating agent. Laboratory tests were carried out with different extraction equipment: mixer settlers, contactors and columns. It was demonstrated that the highest efficiency of the process is reached by using a pulsed column with organic/aqueous ratio of 5/1. At the pilot scale with a pulsed column using an industrial electrolyte, the yield of recovery is high, and the recovery from the strip solution is easy and complete.
