CO₂-Driven Metal Recovery from Reactive Ores
THE CHALLENGE
The challenge lies in developing a cost-effective, scalable process that can both capture CO₂ and extract critical energy metals from ultramafic and mafic rocks, especially mine tailings. Currently, these two goals are tackled separately using energy-intensive and chemically harsh methods that are expensive, waste-generating, and often...

CO₂-Assisted Grinding for Energy and Emissions Reduction
THE CHALLENGE
The mining industry faces a major business and sustainability challenge: the energy-intensive process of grinding ore to extract valuable minerals is consuming up to 4% of global electricity and nearly half of a mine’s on-site energy—driving up operational costs and carbon emissions. Traditional solutions like larger ball...

New Carbon Dioxide Absorbent Material
trong>THE CHALLENGE
Concerns of global warming have been growing over the last decade. One of the driving forces of these concerns is the amount of carbon dioxide in the atmosphere. It allows more heat into the atmosphere than most other particles while also remaining in the atmosphere for a very long time. Due to this, methods for absorbing and utilizing...

A Novel One-Pot Process for Synthesis of Graphene and Graphene-Derivatives from Coals
Graphene is a potential "miracle" material with superior properties of tensile strength, thermal and electrical conductivity, and corrosion resistance. Current graphite-based production processes result in very high priced graphene (a gram of graphene oxide can cost over $150), which acts as barrier for commercial exploitation of this remarkable...
