| titleOfInvention | Process for the microbial oxidation of sulphidic wastes |
| abstract | Process for treating optionally oxidised sulphidic material containing one or more heavy metals, comprising aerobic microbial oxidation of the optionally oxidised sulphidic material in an aqueous suspension using a sulphur oxidising micro-organism to convert optionally oxidised sulphide into soluble sulphate at a pH such that most of the heavy metals are present in an insoluble form. The sulphidic material is especially sulphidic waste, preferably sulphidic slag. The formed sulphate is environmentally less harmful than the sulphide, while the heavy metals compounds are suitable for recovery of the metals using known methods. |
