Chemical Composition

Elemental breakdown by percentage weight.

Standard composition limits
Values represent maximum allowed percentage unless otherwise noted.

Physical Properties

Material form, density, and contamination specifications.

Post-use mobile phone circuit boards; ultra-miniaturized personal device components; HIGH precious metal density (0.03-0.20g gold highly concentrated; 10-50g copper; up to 3g silver); ubiquitous consumer e-waste stream (345 suppliers; highest-diversity source); volume-driven bulk commodity; high precious metal concentration per unit weight (miniaturized); RoHS-compliant modern standard; battery-separation protocols important (lithium-ion hazmat)

Acceptable Inclusions
  • Gold plating 0.03-0.20g (mobile specification; high density)
  • Copper 10-50g (base metal; valuable)
  • Silver <3g (precious metal component)
  • Palladium <0.5g (ultra-precious trace)
  • Solder 2-15g (lead-free modern)
  • PCB substrate 5-30g (miniaturized light)
  • Semiconductor 5-25g (component)
  • Dust/residue typical (consumer use)
Prohibited Materials
  • Gold <0.03g (below mobile specification)
  • Batteries attached (active hazmat; CRITICAL)
  • LCD/display components (hazmat secondary)
  • Mercury components (mobile non-compliant; rare)
  • Severe contamination (water damage, corrosion extreme)
