RE:Smelters need support to survivegreasemonkies. Nice to see Ferro Chrome & Chrome related Alloying Furnaces are rightfully not being called smelters as Chromites, including ROF Chromites, are not sulfides. KWG's Chromite to Ferro Chrome Custom Treatment Furnaces powered by Natural Gas, probably augmented with Oxygen from a small O2 plant, to maximize in-furnace heat transfer are definitely not smelters.
