Reference values

The published values the calculator uses. Per-item values are used when you enter the number of items. Otherwise the category average by weight is used.

Facility recipes

Expected output fractions per category, from the facility spreadsheet (version 1). Changing a percentage saves a new version, and earlier versions are kept.

Listed but not used in calculations

  • Ga, Nb, Ru, Ir detected by XRF in removed components (Charles et al. 2020) — no concentration
  • Sc up to 31 mg/kg and Ce up to 13 mg/kg across 16 equipment types (Priya & Hait 2018) — upper values only
  • Pt in integrated circuits below the quantification limit (Sideris et al. 2025)
  • LED 2700 K table in the source repeats the phone-component numbers — held back until confirmed
  • Wagner et al. — 4,051 PCB composition records, 19 elements, 1990–2020 (Urban Mine Platform). Verified to exist; not audited or imported.
  • Gonzalez Baez et al. (2022): REE concentrations rise in finer particles (Spearman −0.57 to −0.98 for Y, La, Nd, Dy); fractions < 0.5 mm held ~40–80% of measured REE mass. Rank correlations, not prediction equations — assay dust and fines as separate outputs.
  • EU lists: an elemental assay alone does not prove grade qualifications (e.g. battery-grade manganese, rare earths for permanent magnets).
  • Korf et al. (2019): different laboratory methods can give significantly different PCB results, especially for precious, specialty and rare-earth elements. Compare measurements with care.
