abstract:
In the present work chemical basic leaching of pure Stibnite (Sb2S3) by Na2S and NaOH under different
experimental conditions at 40°C, has been studied in order to optimise the reagent concentrations for the
antimony dissolution process. Response Surface Methodology has been used to find the best experimental
concentrations to maximise the Sb extraction yield. 98-100% of antimony recovery was obtained by using
1g NasS and 1g NaOH per gram of pure stibnite. © 2001 SDU. All rights reserved.
