Abstract
Organic and aqueous phases are separated from solvent extraction emulsions by treating with diatomaceous earth at high temperature. Sludge is removed from mixer-settler units by sorption and filtration. Thus, a sludge containing lix-64n, kerosine, and a copper electrolyte consisting of 25-50 g/l cu (as cuso4) and 160-200 g/l h2so4 was stirred with 2.6 G/100 ml of diatomaceous earth at 55 deg c and separated in a vacuum funnel. The resulting clear lix-64n- kerosine and cu electrolyte solutions disengaged rapidly after 5 min of stirring.
