…Iron is an essential limiting factor for the uptake of macronutrients in phytoplankton. Typically, with iron concentrations below 0.2nM, phytoplankton cannot absorb macronutrients (especially nitrates) for photosynthesis. The major source…
Direct reduced iron (DRI) is produced by reacting iron ore with H2-rich syngas, fueled by natural gas, in over 150 facilities worldwide. Direct reduced iron costs $300/ton, consuming 3,000kWh/ton of…
…is near the melting point of iron/iron ore. What materials could serve as current collectors for these cells? Most conductive metals, and even most super-alloys, have melted by 1,500C. There…
…case is a marginal cost of $550/ton and 2.4 tons of CO2 emitted per ton of steel. $559.00 – Purchase Checkout Added to cart Blast furnaces reduce iron ore into pig iron,…
Electra is developing an electrochemical refining process, to convert iron ore into high purity iron, and ultimately into steel, using only renewable electricity. It has raised c$100M, gained high-profile backers,…
Bioleaching uses bacteria to metabolize insoluble sulfides and iron complexes. It produces 20% of the world’s copper, and other metals; with 50% lower capex, at least 50% less CO2 and…
Vast quantities of gold hydrogen are produced in the Earth’s subsurface, via the serpentinization of iron-containing Peridotite rocks. Gold, white and orange hydrogen variations aim to harness this hydrogen. This…

…demand in abundant global commodities are surprisingly hard to find. The Iron Age officially ended in AD43 when the Romans brought new technology to Britannia, yet global iron/steel demand remains…
Lithium ion batteries famously have cathodes containing lithium, nickel, manganese, cobalt, aluminium and/or iron phosphate. But how are these cathode active materials manufactured? This data-file gathers specific details from technical…
