# Minerals

### Barite

![](/files/uypxeidFHU9ytvKs9QQJ)

*Barite is the primary, naturally occurring, barium-based mineral. It is typically used for its coloration to make colorful fireworks and in advanced regolith mining techniques. It can gathered from scavenging the surface, as a byproduct from mining ice and regolith.*
