Copper value ladder

From half-percent rock to grid-grade commodity.

Price per kilogram versus annual material scale, log-log. Diagonal guide lines are rough iso-value bands. The charts move from copper's process ladder to broad commodity domains, then into food commodities where calories, protein, spoilage, and consumer preference create very different market shapes.

Axes: x = gross value per kg of material; y = annual mass flow. Values are deliberately rounded.

Copper value map A log-log chart of material price per kilogram against annual mass flow, showing copper's route from low grade ore through leach solution and cathode to electrical products.
How to read it: moving right means each kilogram is worth more; moving down means the material stream is smaller. The metallurgical trick is not magic price discovery: it is selective removal of waste mass. SX/EW turns dilute copper dissolved by sulfuric acid into cathode without sending the material through a smelter.

Commodity market boxing map A log-log chart comparing oil, coal, natural gas, solar modules, batteries, copper, lithium carbonate, nickel, steel, cement, ammonia, grain, and semiconductors by price per kilogram and annual mass flow.
Market boxing: the same diagonal can contain totally different businesses. Oil and coal are giant low-margin rivers; lithium carbonate and polysilicon are smaller but strategically levered; semiconductors are physically tiny but economically huge. The location of a point suggests what matters most: logistics, geology, permitting, learning curves, purity, or IP.
Box reading rule:
annual market value ≈ price/kg × kg/year
lower-left = bulk logistics
upper-right = giant rent pool
lower-right = scarce/high-value bottleneck
values are 2024-2026 order-of-magnitude estimates.
Food map: annual physical flow versus rough bulk price. This frames food as logistics + biology + shelf-life, not just calories.

Food commodity boxing map A log-log chart comparing major food commodities including corn, rice, wheat, soybeans, sugar, vegetable oils, milk, meat, coffee, cocoa, and spices by rough bulk price and annual physical flow.
Food boxing: grains sit in the mega-ton, sub-dollar/kg world where storage, trade corridors, weather, and policy dominate. Protein and dairy move up in value because biology converts feed into fewer kilograms. Coffee, cocoa, and spices are tiny in mass but high in attention, labor intensity, brand value, and climate/geography constraints.
Food reading rule:
staples = calories + storage + freight
proteins = feed conversion + cold chain
softs = terroir, labor, brands, shocks
values are rounded global production / bulk-price estimates, not retail prices.
