Rust

Rust

Rust is an iron oxide that forms from the breakdown of Iron. It is useful in some Oxygen production processes.

Rust is a Consumable Ore, available in the Rust Biome.

Usage

The Rust Deoxidizer can produce Oxygen , Chlorine , Iron Ore with Rust and Salt : 750 g/s Rust + 250 g/s Salt = 570 g/s Oxygen + 30 g/s Chlorine + 400 g/s Iron Ore.

Heating Rust over its melting point will turn it into Molten Iron with a 1:1 ratio, which can then be cooled into refined Iron . The conversion is 87.5% more efficient than what can be achieved with a using Rust Deoxidizer, but doesn't produce Oxygen or Chlorine. In case an Iron Volcano is available, it's more worthwhile to use the Rust Deoxidizer, as Iron Ore is more difficult to produce in other means.

Production

It can be harvested on rocket missions to renewable Space POIs:

• In Oxidized Asteroid Fields at a rate of 432 – 1296 kg per cycle.
• In Radioactive Asteroid Fields at a rate of 18.2 – 72.8 kg per cycle.

It is produced by Jawbos.

Tips

Magma spawns from Volcanoes with a high enough temperature to melt rust. That temperature can also be reached by using Liquid Steel as "coolant" in a Metal Refinery. In both cases, reusing the heat from the resulting iron to preheat more rust will make the process much more heat-efficient. A properly designed rust melter may later be used to refine most other Metal Ores faster than with a metal refinery or it can be converted into a Regolith melter.
