Angel's Smelting Bob's Mods Ratios [Updated for 2.3]

2017.5.29 Re: Angel's Smelting Optimum Ratios with Bob's Mods. Jackalope wrote: 6 iron ingots and 6 oxygen gas get turns into 3 steel ingots, then 2 steel ingots get turns into 2 molten steel, and 2 molten steel gets turned into 2 steel plate. It's the exact same 2 iron to 1 steel ratio as in baseline Bob's mods.

Driving investments in ore beneficiation and scrap upgrading

2021.5.20 The pressure on the steel industry to reduce its carbon footprint has led to discussions to replace coke as the main reductant for iron ore and turn to natural gas, bio-syngas or hydrogen. Such a major transition from the blast furnace-basic oxygen furnace route, to the direct reduction-electric arc furnace route, for steel production would
