Overview
Background
My research portfolio integrates, at a deep level, fundamentals of process engineering and molecular & microbiology across applications including biominerals engineering, bioenvironmental systems, valorisating & repurposing waste, bioproducts and algal biotechnology. Integrating microbial dynamics and structure – function relationships informs building robust & resilience bioprocesses and novel bioproducts. Using IDTD research, I seek sustainable approaches to mineral & water-sensitive systems

High Voltage Pulse (HVP) Enhanced Leaching of Mineral Ores
Project description
High Voltage Pulse (HVP) technology is an emerging innovation that offers several potential advantages to the mining industry. Utilizing high-voltage pulses for ore fracturing is a groundbreaking approach that has attracted attention in various sectors, particularly mining and oil extraction. While HVP has proven effective in enhancing mineral liberation and pre-weakening for subsequent processing steps, its direct application in leaching remains under-explored.
The potential for leveraging HVP to improve the leaching process presents a promising avenue for future research and innovation. The key objectives of the project are to:
- Assess the suitability of different ores for HVP-enhanced leaching
- Evaluate the sustainability of HVP-enhanced leaching
- Explore scalability and integration possibilities
