Flow

Direct steps

  • Void Extractor → Raw realgar (60 %) (60 % / 32 s)

How to build

  1. Same Electric Ore Factory as the silver line (30 EU/t, 8 s): 1 crushed sphalerite + 100 mB water → 1 sphalerite dust, +1 (75 %), 1 gallium dust (45 %), 1 sulfur dust (32.5 %). Sphalerite comes from the gravel sieve (16 per batch). Give it its own input bus drawer so galena and sphalerite never mix. — gtceu:electric_ore_factory, gtceu:crushed_sphalerite_ore, gtceu:gallium_dust
  2. Void Extractor: 5 B drilling fluid per 32 s (30 EU/t) gives raw realgar at 60 % (+12 % per tier over LV) with the other ores. Filter only raw realgar and raw silver into drawers. — gtceu:void_extractor, gtceu:raw_realgar, gtceu:drilling_fluid_bucket
  3. LV Pulverizer (pack machine): 1 raw realgar → 2 crushed realgar ore, 30 EU/t, 15 s (it copies the macerator’s crushed-ore count). The Pulverizer only does raw ore → crushed ore (and heated smelting variants); it has no crushed → dust recipe. — gtceu:lv_pulverizer, gtceu:crushed_realgar_ore
  4. LV Macerator: crushed realgar ore → 1 impure realgar dust (recipe 2 EU/t, 20 s base, so about 10 s at LV) plus a small chance of a bonus dust. — gtceu:lv_macerator, gtceu:impure_realgar_dust
  5. LV Ore Washer, ghost circuit 2: 1 impure realgar dust + 100 mB water → 1 realgar dust in 0.4 s (4 EU/t). A Centrifuge also cleans impure dust but is far slower. — gtceu:lv_ore_washer, gtceu:realgar_dust
  6. LV Centrifuge on the realgar dust drawer: realgar is 4 arsenic + 4 sulfur, which GregTech reduces to 2 realgar dust → 1 arsenic dust + 1 sulfur dust, 30 EU/t, about 64 s. Counts come from the standard decomposition code, not from a local dump: confirm in EMI. Keep only the arsenic. — gtceu:lv_centrifuge, gtceu:arsenic_dust
  7. LV Mixer with ghost circuit 1: 1 gallium dust + 1 arsenic dust → 2 gallium arsenide dust in 10 s (7 EU/t). Output drawer capped by a Robot Arm cover on Keep Exact 16: that is already 64 MV circuits. — gtceu:lv_mixer, gtceu:gallium_arsenide_dust

Tips

  • 1 gallium + 1 arsenic = 2 gallium arsenide dust = 8 small dust = 8 diodes = 4 MV circuits. Gallium and arsenic are always used in equal numbers.
  • Plain electrolysis of sphalerite dust also gives gallium but only 5 % per craft; the Electric Ore Factory gives 0.45 per crushed sphalerite.
  • Arsenic is the slow part: the only source in reach is realgar, and only the Void Extractor makes it (no sieve in this pack gives it). Count: 1 raw realgar → 2 crushed → 2 impure dust → 2 realgar dust → 1 arsenic dust (+1 sulfur dust).
