Studies on the Enhancement of Solute Recovery in Leaching Operation

Abstract

Leaching operation is the most generally used operation in industries.  In this paper, a system of sand (solid)-Na2CO3 (solute) is taken and from that the recovery of Na2CO3 has been studied by using water as solvent. In this process, we first focused on how the recovery of solute was being affected by the weight of the solute (5, 10, 15, 20, 25 gm) in the mixture and percentage recovery trend was observed and the data was recorded. Then the variation of solute recovery with the weight of solute containing solid (5, 10, 15, 20, 25 gm) was studied and the trend was observed and recorded. Finally we studied about the variations of recovery with the volume of solvent (75, 100, 125, 150, 175 ml) used for the recovery. Then we plotted the characteristic curves for the all the experimental data obtained by the leaching operation.
