Background
- Jarosite waste contains arsenic, posing environmental risks through leaching.
- Arsenic contamination from industrial waste requires effective remediation strategies.
Purpose Of The Study
- To investigate the hydrometallurgical recovery of arsenic from jarosite waste.
- To optimize arsenic recovery using response surface methodology (RSM).
Main Methods
- Jarosite samples were characterized using XRD, FTIR, SEM, and EDX.
- Response surface methodology (RSM) was employed to optimize arsenic recovery.
- Key factors studied included dosage, time, temperature, and acid concentration.
Main Results
- Arsenic recovery from jarosite was optimized using RSM.
- Dosage and acid concentration significantly enhanced arsenic recovery.
- Optimal conditions achieved approximately 52.61% arsenic recovery at 2.5 g jarosite, 10 mol/L acid, 150 min, and 80°C.
Conclusions
- This study presents the first report on arsenic removal from jarosite waste via hydrometallurgical treatment.
- The findings highlight the potential for arsenic recovery and waste management.
- Further optimization by adjusting operating parameters is recommended for improved yield.

Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...
After filtration, the precipitate is washed to remove coprecipitated impurities and any remaining mother liquor. Colloidal precipitates, such as silver chloride, are washed with an electrolyte (such as dilute nitric acid) to prevent the peptization of the precipitate. In the case of slightly soluble precipitates, the wash solution contains a common ion to reduce solubility. Lead sulfate, which is slightly soluble in water, is washed with dilute sulfuric acid. Similarly, wash solutions may be...
