Drift into a calm, expansive journey through the hidden world of critical minerals — the elements that power nearly everything in modern life. From the lithium inside electric vehicles to the rare earth metals that make smartphones vibrate, the materials we rely on each day travel through vast, intricate supply chains shaped over decades.

In this SleepWise story, we trace these minerals from their geological origins to the global industries that refine and transform them. You’ll learn how lithium is extracted from salt flats and hard-rock mines, how cobalt and nickel move through Africa and Southeast Asia, and why rare earth elements require some of the most complex chemistry in the world.

But the heart of the episode explores a deeper question: how did China become the central hub for refining, processing, and manufacturing the world’s most essential minerals?

We walk softly through China’s long-term strategy — the early investments, industrial clusters, low-cost refining, and decades of learning-by-doing that allowed it to dominate the midstream stages of the supply chain. As Western countries reduced their own refining capacity, China built the infrastructure, talent, and scale that now support the global energy transition and digital economy.

Along the way, we visit the landscapes behind these materials: quiet open-pit mines at dawn, the steady hum of refineries, and the immense factories that shape batteries, magnets, and electronics. We explore the environmental and social complexities of mining, the changing geopolitics of resource nationalism, and the future possibilities of recycling, new battery chemistries, and diversified supply chains.

This is a soothing, deeply informative exploration of how the world’s most important materials move from ancient rock to the devices resting beside you. A calm, immersive story for curious minds — and a gentle way to understand the systems that power our daily lives.

Listen, unwind, and drift into the hidden world beneath modern technology.
