With a total of 4 patents to his name, his work focuses on innovative methods for metal recovery and the production of transition metal compound particles.

Latest Patents

Madhav's latest patents include a method for the integrated recovery of metals from complex substrates. This method involves contacting a substrate containing metal sulphide or metal oxide with an aqueous oxidant. The process oxidizes the metal sulphide to elemental sulphur and oxidized metal, or converts the complex metal oxide to a metal salt. The oxidized metal is then treated with ammonium hydroxide to form a soluble ammine complex, leading to the separation of leachate from residual solids for metal recovery.

Another significant patent describes a method for preparing insoluble transition metal compound particles. This involves providing a transition metal salt solution and a source of an anionic compound that reacts with the metal to form particles. The process includes sonication in a reaction chamber, resulting in particles with a narrow size distribution and a tap density of about 1.7-2.3 g/mL.
