... are you sure about that? I haven't pulled the paper, but the abstract suggests that doing exactly that was central to the research.

- lukan 2y agoI probably should get the actual paper, yes. The articles are not that great, one has to read between the lines, that they talk about iron ore and not pure iron. Or rather iron slag. The byproduct of melting. But I meant the economics of getting the liquid iron (or slag) to the holes. If there were many furnaces nearby, maybe they just used that and carried it some meters, but longer distances?
