  <dc:description xml:lang="eng">ABSTRACT: This paper presents an investigation of low-grade copper ore leaching using sulphuric acid
where dissolved oxygen and iron(III) ions play a role of oxidant. The influence of initial acid concentration
on copper and iron extraction was examined. The copper concentration in the leach solution ranged from
0.78 to 1.25 g/dm3, whereas the iron concentration ranged from 1.89 -2.32 g/dm3. It was found that the
metal extraction increases with increasing acid concentration. The total copper extraction of 38% was
attained with 0.5 M H2SO4 after 180 min of reaction.</dc:description>
