Nickel
While the world’s largest nickel mines are often visualized as massive craters in the earth, the real story of 2025 isn't just about what is being pulled out of the ground—it's about the high-stakes chemistry happening right next to it.
The infographic covering 2023 production data highlights the sheer scale of the Weda Bay Project, but the true disruptor is a single acronym: HPAL. This technological “skeleton key” has allowed Indonesia to unlock massive reserves of low-grade ore and convert them into the high-purity, battery-grade nickel that the EV industry craves.
The Global Shift: From Sulfide to Laterite
Historically, the nickel industry was a "club" of high-grade sulfide mines in cold climates. Today, the center of gravity has shifted to tropical laterite deposits.
Turning "Dirt" into Gold
High-Pressure Acid Leaching (HPAL) changed the math. By "cooking" laterite ore at extreme temperatures and pressures, miners can now chemically extract nickel and cobalt with surgical precision. This process creates Mixed Hydroxide Precipitate (MHP)—the low-cost feedstock currently fueling the global battery boom.
Why Indonesia is Now the "OPEC of Nickel"
In 2018, Indonesia was a major player, but not a hegemon. By banning raw ore exports, the government forced giants like Tsingshan and Huayue to build massive refining complexes on-site, leading to a production explosion that has left other nations in the dust.
The result? A vertically integrated powerhouse. Indonesian processing costs now sit at roughly $4.50–$6.50/lb, nearly half the cost of traditional operations in Australia or Canada.
The Paradox: Green Metal, Black Energy
The rise of Southeast Asian nickel comes with a shadow. To run the massive autoclaves required for HPAL, many industrial parks rely on captive coal-fired power plants.
As Western automakers face stricter "Green Passport" regulations, the next battle won't be fought over volume, but over carbon intensity.

Apple Outweighs Every Listed Miner on Earth, and It Is Not Even the Biggest Company
One consumer-electronics company is now worth more than every publicly traded mining company on Earth combined. The graphic above captures the June 5 snapshot, when the 317 publicly traded miners tracked by CompaniesMarketCap were worth about $3.48 trillion

Three Weeks Public, SpaceX Already Approaches the Value of Every Listed Miner on Earth
For 24 years SpaceX stayed private. Then, on June 12, 2026, it began trading on the Nasdaq in the largest IPO in history, priced at a $1.77 trillion valuation. Barely three weeks later the rocket and satellite maker is worth even more. As of early July, SpaceX carried a market capitalization of about $2.1 trillion, the seventh-highest of any public company on Earth, and it joins the Nasdaq-100 on July 7

Mapped: Zinc's Use Across Five Industries and the 2030 Demand Outlook
We've covered zinc's role in energy, health, and sustainability before, alongside the supply base concentrated in a handful of mega-mines and the production map that has shifted toward Asia since the mid-1990s. The story of 2025 is what changed on the demand side. In November, the U.S. Geological Survey retained zinc on its final 2025 List of Critical Minerals.
Lithium Use Cases: Batteries Now Consume 88% of Global Supply
Lithium Use Cases: Batteries Now Consume 88% of Global Supply
In February 2026, the U.S. Geological Survey put a fresh number on a transformation that has been building for a decade: batteries now account for 88% of global lithium end-use, up from 87% a year earlier. The metal that once quietly toughened ceramics and thickened industrial greases has been almost entirely repurposed by the battery economy. As covered in our reporting on the shift from surplus to deficit, the supply side of this story is tightening.
