<p>In the leaching of minerals, especially ferrous sulphide ores, it is known that certain bacteria, especially Thiobacillus, can oxidise the ore to ferric sulphate. The ferric ions can convert other metal species to the soluble state. The invention proposes supplying oxygen to these bacteria by supplying it in combined form, e.g. as hydrogen peroxide, a per compound or a peroxygen addition compound.</p> |
