Raw Materials & Commodities parts lists
BOMwiki maps 107 raw materials & commodities products, each exploded into a recursive bill of materials: 450 parts in total, down to individual fasteners and cells. The largest is the indium phosphide wafer at 20 parts across 4 top-level assemblies; the simplest is the zinc ingot at 4. Across the domain the same components recur: casting stage, cementation stage, crude indium anode and electrorefining cell appear in most of these machines, and each is a single shared page here, so a correction to one fixes every product that uses it. Open any product for its parts diagram, the function of each part, and the full bill of materials.

Shared components ranked by how many of the 107 products in this domain contain them, directly or inside a sub-assembly.
- Casting Stage in 2 of 107 productsCathode metal is melted under cover gas around 200 °C and cast to standard shapes.
- Cementation Stage in 2 of 107 productsMetallic indium is displaced from the strip solution onto aluminium or zinc sheets as a spongy deposit.
- Crude Indium Anode in 2 of 107 productsCast anode of cement indium; impurities either dissolve and stay in solution or drop to the cell bottom as slime.
- Electrorefining Cell in 2 of 107 productsTank cell with chloride electrolyte; one to two passes reach 99.995%, with zone refining beyond 6N for semiconductor use.
- Electrorefining Stage in 2 of 107 productsCrude anodes dissolve in a chloride electrolyte and 4N5–6N indium plates onto cathode sheets; cadmium, thallium, and tin stay behind.
- Hydrometallurgy Stage in 2 of 107 productsResidues are dissolved in sulfuric acid and the indium pulled selectively out of solution by solvent extraction.
- Indium Cathode Deposit in 2 of 107 productsRefined indium stripped from titanium cathode blanks, ready for melting.
- Ingot Casting in 2 of 107 productsIndium melts at 156.6 °C; ingots are stamped with purity grade and lot, the form commodity traders and ITO target makers buy.
- Ore Stage in 2 of 107 productsIndium rides into the supply chain inside zinc sulfide ore at 10–100 ppm; roughly 20 tonnes of concentrate pass through a smelter for each kilogram of indium recovered.
- Smelter Byproduct Stage in 2 of 107 productsDuring roasting and leaching of zinc concentrate the indium concentrates into flue dusts and leach residues rather than the zinc product.
- Solvent Extraction Circuit in 2 of 107 productsMixer-settler stages with di(2-ethylhexyl) phosphoric acid (DEHPA) in kerosene; indium loads into the organic phase and is stripped with hydrochloric acid.
- Sphalerite Zinc Ore in 2 of 107 productsZinc sulfide ore; indium substitutes into the sphalerite lattice at parts-per-million levels and is invisible until smelting.
