Solvent Extraction

In comparison, solvent extraction with hexane (the primary solvent used worldwide) will remove all but about ½% of residual oil, uses less horse power, and requires less maintenance. It is relatively efficient and reliable, and this is one reason why solvent extraction is the primary means of separating large tonnages of oil from protein meal.

A Review on Germanium Resources and its Extraction by

Cementation, precipitation, membrane, ion exchange, and solvent extraction were reviewed as a solution purification step for the recovery of Ge(IV) from leach liquors. Several hydrometallurgical processes for the recovery of Ge(IV) from the main germanium-bearing resources were compared in terms of process efficiency and environmental burden.

Solvent Extraction

Solvent extraction is a simple process in which oily waste and solvent are mixed in an appropriate proportion to ensure adequate miscibility of oil in solvent, while most water and solids are rejected as unwanted impurities that may be removed by gravitational settling or centrifugation. The oil and solvent mixture can then be separated by distillation (Hu et al., 2015).
