MUMBAI, India, July 11 -- Intellectual Property India has published a patent application (202521060452 A) filed by Premchandra Jagannath Lokhande, Pune, Maharashtra, on June 25, for 'a system and method for programmable pyrometallurgy via resonant-frequency plasma ignition and magnetohydrodynamic separation.'
Inventor(s) include Premchandra Jagannath Lokhande.
The application for the patent was published on July 11, under issue no. 28/2025.
According to the abstract released by the Intellectual Property India: "A System and Method for Programmable Pyrometallurgy via Resonant-Frequency Plasma Ignition and Magnetohydrodynamic Separation." A system and method for the controlled ignition and subsequent processing of exothermic chemical reactions are disclosed. The system integrates two novel phases: a resonant-frequency plasma ignition phase and a magnetohydrodynamic (MHD) separation phase. In the ignition phase, a variable-frequency microwave generation system emits precisely tuned radiation into a reactant-filled vessel to perform a dual function: (1) It excites a molecular resonance within the reactant mass for energetic conditioning, and (2) It ionizes an inert gas to create a stable, large-area plasma sheath. This plasma sheath is biased with a DC potential to function as a contactless, non-contaminating anode, which delivers a uniform ignition current to the cathodic reactant mass. Following the reaction, the system initiates the MHD separation phase. An array of external electromagnets generates a shaped magnetic field that permeates the now molten, conductive products. The resulting Lorentz forces actively separate the lighter slag components from the denser metal components, enabling their rapid and pure extraction. An AI controller manages the entire process, providing a fully programmable and automated pyrometallurgical solution."
