Recovery of both sulfuric acid and zinc from the spent zinc bleed stream(SZBS) generated during the electrowinning of zinc in the zinc refineries using tris-(2-ethylhexyl) amine (TEHA) dissolved in kerosene has been investigated in detail. Extraction was studied under various experimental conditions such as concentration of TEHA in the organic phase and temperature, concentration of acid and zinc...
The extraction of sulphuric acid from the actual solutions generated during the process of pickling of steel from a local tube company dealing with the processing of iron and steel tubes using Alamine 336 has been studied in detail. Various parameters were optimised for the maximum extraction of acid such as concentration of organic extractant, time for equilibration, O/A ratio, acid concentration...
