Process Burnt Slag using high-elevation drops and the Kinetic Slag Press to produce gold and spores in Sandustry.

Kinetic Impact Stamping and Slag Refining

By dropping dense Burnt Slag directly onto the Kinetic Slag Press from an elevated height, mechanical impact crushes the material, refining it into pure Gold and reproductive Spore units.

Thermal Smelting into Burnt Slag

Before slag can be stamped, raw byproduct Slag from sand shakers (sourced from lines built in the shaker refining guide) must undergo thermal conditioning. Routing raw slag through a high-temperature zone or applying controlled heat alters its structural composition, producing burnt slag ready for the impact press.

Vertical Launcher Columns and Drop Elevation

Stacking multiple Launcher modules constructs a vertical lift tower, applying the multi-tier designs outlined in the factory layout and launcher guide. Prepared burnt slag shoots upward to the tower summit before tumbling down a reinforced vertical drop shaft onto the target anvil.

Downstream Sorting: Gold and Spore Separation

Upon kinetic impact, the press discharges both mineral gold and organic spores simultaneously. Placing an Allow Filter downstream separates dense gold into collection vaults while channeling spores toward moisture tanks and Planter Box facilities — linking directly into the agricultural cycle detailed in the spore cultivation guide.

Impact Alignment and Missed Drop Troubleshooting

A frequent engineering defect is failing to enclose the vertical drop chute. Because granular solids tumble with physics momentum, dropped slag can bounce off the press perimeter if dropped without guide walls. Constructing containment blocks on either side of the drop shaft ensures every falling block lands squarely on the pressure plate.

Step-by-Step Walkthrough

  1. Collect raw byproduct slag from shaker outputs and route it through thermal smelting.
  2. Stack launcher units vertically to build an elevated drop tower above the press.
  3. Drop heated Burnt Slag down the enclosed shaft onto the Kinetic Slag Press anvil.
  4. Install sorting filter gates below the press to separate resulting Gold from Spores.
  5. Enclose the drop chute with solid block walls to prevent falling slag from bouncing off target.
