Latest Patents
Cherian holds a patent for a method titled "Selective bioleaching of zinc." This patent describes a process for selectively leaching zinc from a source material containing zinc in sulphide form and iron. The method involves subjecting the source material to bioleaching using a strict sulphur-oxidizing microorganism or a mixed culture of sulphur-oxidizing and iron-oxidizing microorganisms. This process is conducted in the presence of a nutrient solution containing less than about 15 mg/L phosphate ions. In another embodiment, the source material is in the form of a slurry with a solids concentration of at least about 25% on a weight per volume basis, along with a nutrient solution containing specific concentrations of ammonium, magnesium, and phosphate ions.
