The Emerging Science of Finding Critical Metals | Mfikeyi Makayi | TED
In the TED talk “The Emerging Science of Finding Critical Metals,” Mfikeyi Makayi, a Zambian born into a copper mining legacy, explores the future of sustainable mining. He argues that to transition to a circular economy—which relies on electrifying everything from transportation to technology—we need an abundance of critical metals like lithium, copper, cobalt, and nickel. However, the mining industry has stagnated in innovation, with less than one cent of every dollar returned to shareholders being reinvested in exploration.
Makayi emphasizes that while many past mines were easily discovered, the majority of ore deposits still exist but are harder to find. The solution lies in utilizing advanced machine learning technologies that can predict mineral concentrations beneath the surface far more efficiently than conventional methods. By embracing data-driven predictions, the industry can optimize mining operations to be environmentally responsible and economically viable.
He introduces the KoBold project, which seeks to revolutionize mine design and operations through sophisticated simulations that incorporate uncertainties. This ensures that mining practices are not only profitable but also safe and sustainable. Ultimately, Makayi’s vision outlines the imperative for a responsible mining revolution to meet the growing demand for critical metals while safeguarding the environment and supporting local communities.
