Zero Carbon Mining and Metals Production

by-product of the need to add carbon

I covered this in another thread…

Electric and Alternative Vehicle Fuels

It isn’t minuscule. Some steel products have up to >2% carbon content by weight. Depending on the steel…it ranges from 0.05-0.25% for mild , 0.29% to 0.54% for medium, 0.55% to 0.95% for high and 0.96% to 2.1% for very high carbon steel. Pig iron is even higher at 3.8–4.7% carbon. As the world produced around 1800 million tonnes or steel in 2018, the amount of carbon used in steel production world wide is significant. At say a conservative average of 0.5% carbon in steel content, this is about…

Carbon does and is needed to change the properties of steel…and the volumes needed to satisify global steel production is significant. It could be replaced with say biomass based carbon, but this may also have impacts as well.
