Abstract
Abstract
| The kinetics of the leaching of antimony oxide ore (Sb2O4) in aqueous hydrochloric acid solutions has been investigated. This dissolution reaction is a heterogeneous solid-liquid reaction. It has been found that the leaching temperature and the concentration of hydrochloric acid turn out to be the significant influencing factors on the leaching rate. The apparent activation energy for the leaching reaction was determined to be 63.5 W/mol within the experimental temperature region of 50O to 90O C. The experimental results indicate that the leaching process is controlled by the rate of the chemical reaction. |
