Abstract
In this this article ,a solvent extraction method by using sulphuric acid leaching was developed .The process
conditions and parameters of sulphuric acid concentration ,leaching temperature ,leaching time and solid
to liquid ratio were studied. These studied conditions and parameters were varied from 0.5M to 5M at 0.5 M
interval, 30oC to 60oC at 5oC interval and 30 minutes to 240 minutes at 30 minute interval respectively. The
solid to liquid ratios used were 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, 1:10.The optimum percentage extraction
efficiency of magnesium as found to be 66.87% at optimum operating conditions of 4M sulphuric acid
concentration 60oC leaching temperature, 120 minutes leaching time and 1:2 solid to liquid ratio.
