abstract = "One of the most challenging issues of the actual steelmaking industry is the mitigation of CO2 emissions. To cope with this target, the massive use of granulated biomass and fuel gas in the iron ore sintering process are a promising technological solution and can contribute to mitigating the environmental impacts of the steel plant.

Mini mills, the result of innovative technology and market competition, are smaller, cheaper, and more flexible than traditional integrated mills. Instead of creating steel from iron ore and coke, as integrated mills do, mini mills melt steel scrap. They are less dependent on natural resources and require less space, so there is more freedom to ...

The iron totems should begin spawning iron ore and dropping it along your conveyor belt. If done correctly, the iron ore will ride the conveyer belt through the smelter, turn to iron, and then continue riding the conveyer until it enters the industrial chest that you've placed at the end. Collect your iron from the chest.

On the other hand, integrated mills in inland areas suffer from high transportation costs of imported iron ore. These factors are likely to concentrate large-scale integrated mills along waterways—rivers, lakes, or coasts—while EAF mini-mills spread widely across mainland China.
