Critical Materials and Minerals Expo 2026

The Critical Materials and Minerals Expo is coming to the Cobb Convention Center in Atlanta, running from Wednesday, October 28, through Thursday, October 29, 2026. It's a two-day exhibition focused on critical materials and minerals, the kind of stuff that doesn't usually make the headlines but ends up in almost everything we use. If you've ever wondered about the raw materials that go into batteries, electronics, or green energy tech, this is where you'll find them on display.

The expo brings together the industry around these materials, so you'll see a range of exhibitors showing off different minerals and the processes used to get them from the ground into a usable form. It's a trade show at its core, which means it's built for people who work in mining, materials science, and manufacturing, but it's open to anyone interested in how these supply chains actually work. You can walk the floor, see the materials firsthand, and talk to the people who deal with them every day.

Because it's a two-day event, you've got a bit of flexibility on when to go. It opens on Wednesday, October 28, and runs through Thursday, October 29, at the Cobb Convention Center, which is part of the Cobb Galleria Centre. If you're coming from across town, keep in mind that the venue is in the Cobb area, so you'll want to plan your trip accordingly. It's a straightforward setup: two days of exhibits on critical materials and minerals, right here in Atlanta.
