Fluxite is the rare purple resource that upgrades your mining tools, weapons and drones in Sandustry. It is the single most important late-game resource, so getting a steady supply is the difference between a factory that struggles and one that runs itself.
There are two ways to get fluxite:
- Mine it — fluxite generates naturally in the world, in trace amounts underground. A shovel can dig it (it is medium-hard, tougher than Dirt), but it is not a reliable long-term source.
- Produce it — build a Flux Emanator, which converts Voidbloom into fluxite at a ratio of 1 Voidbloom → 1 Fluxite. This is the real answer.
The fluxite production line
Here is the full chain, step by step:
1. Grow Voidbloom
Voidbloom is the fuel that feeds the Flux Emanator. You create it by combining Void Petals and Redsand.
2. Feed the Flux Emanator
Drop Voidbloom onto the top of a Flux Emanator. The machine consumes it and fluxite grows from the base below — the conversion is slow, not instant, so feed it steadily to keep production up.
3. Collect the fluxite
Fluxite grows outwards in a circular pattern with the Emanator's base as its centre, following the walls if something blocks it. Dig it up to collect it and route it into storage or straight into your upgrade chain.
What fluxite upgrades
Fluxite is spent on upgrades rather than consumed by recipes:
- Mining tools — faster and stronger digging.
- Weapons — better combat against the creatures you encounter.
- Drones — more capable Sweeper, Digger, Recon and Hauler drones.

New players should pair this production line with the Sandustry beginner guide, which explains the research and machine order needed before scaling it.
